Feeding 5' arapaima, 3' jau, 2.5'-3.5' RTC, & Co in 4500 gal

[@Fish-Story]

I continue getting regular flack and thumbs down for the "overstock", apparently mostly from non-expert folks without a substantial experience in the keeping of monster fish or even sometimes any fish. I also often get comments from people anthropomorphizing fish, which means assigning human values, perceptions, and even sometimes thoughts and feelings to fish. In the interest of saving my time and possibly saving most of these commenters some aggravation I thought I better address it here. “THE OVERSTOCK!!!” ~ To some, who don't know us and our posts on the Monster Fish Keepers and Planet Catfish forums, I totally agree it may look dangerously or unusually heavily stocked. Those peers, who know us, know it is not and there could even be room for more, as hard as it is to imagine. Yes, most our tanks and this particular 4500 gal tank are pretty heavily stocked. There is a way to maintain a heavily stocked tank and not harm the fish. The biofilter sump for this tank has a volume of 15,000 gal and the water flow through the tank is 20,000 gallons per hour of maximally aerated water (water + air together), which means the turnover time is 12 minutes. To the fish health, the total water volume, that is tank + filter, can be more important than the tank volume alone: if the water turnover is fast enough, it asymptotically leads to an equalization of the water in the filter and in the tank, hence, effectively increasing the volume of water available for the all-important instant dilution of toxins produced by the fish, which is then eliminated by the nitrifying bacteria in the filter. I do plan to add a fifth and maybe sixth 5,000 GPH pump to bring the water flow up to 25,000-30,000 GPH and improve the current condition and be able to add to the stock, if found necessary, or more rescues come than go. The water change is continuous, 24/7/365, and results in a 100% water change every 6 days in this tank and all our tanks. Nitrates are 20-40 ppm. The water is pristine in that both ammonia and nitrite are always firmly at 0 ppm by an API liquid test kit and the fish are most usually healthy. In the second half of 2018, we've had a problem with supposedly a columnaris strain but it was brought into the system with new fish from the wild, my error, and I don't believe it had to do with the stock density. It spread to all tanks. We were losing fish from all tanks, including the lightly stocked. There have been concerns raised about stress from the limited freedom of movement and frequent interaction with tank mates. Some of it is valid but not a horrible problem IMHO. Ultimately I admit that we are uncertain of the exact level of stress the fish are under but if a fish feeds, behaves, and looks as expected and lives out a reasonable life span, things must be fine in the first approximation. BTW, generalizing is wrong. There are 30+ fish species in this 4500 gal and most of them look and behave totally natural to me. Yet, surely some things could be improved, for instance, separating Vittatus African tigerfish and golden dorado from each other and from the rest. But I can't fix it immediately. I need to glue more tanks. The acrylic and the glue have already been bought. For now though, the fish that worry me a bit I think are at least adequate. As for the other 4500 gal (with RTC, arapaima, etc.), these fish are mostly rescues and are indeed getting ready for an upgrade to a planned 30,000 gal. IMO, they have been fine in this tank so far. Most of them are 3'. A 3 footer in a 13'x13'x4.5' is not too bad. They swim, grow, and enjoy themselves from the little that I can tell. They have been in there for 3-4 years and grew up in that tank from far smaller sizes. “THE JAIL!!!” ~ Anthropomorphizing fish is not scientifically correct, nor reflects the reality. Passing human traits to a fish, which for the nearly 100% is a” programmed” biological machine with an exceedingly little room for learning, is a crusade against science and knowledge, against our hobby and the first hand learning of nature, and against common sense. Fish don't "think" of, nor “perceive” freedom and space like humans do. The anthropomorphizing logic in its end result IMHO eliminates any and all fish keeping in captivity, or any animal keeping in captivity for that matter. Many fish stay in one rather small part of the overall water body available to them. Not staying in one place usually is driven by diminishing feed availability and, another biggie, by a breeding behavior / migration. Still there are many species that stay, feed, and mate in one “fishing hole” or in the vicinity of some debris despite having a relatively unlimited body of water like a river or a large lake available to them. Another example, many fish have an ocean at their disposal but hang around one coral rock all their lives. There are great dangers associated with traveling away from the safety of home, especially for smaller and medium size fish on menu of large predators. And they are “programmed” to know it. If the feed is plentiful, the mates are near, and it is safe, many fish don’t exhibit any desire to leave and “explore the world” or get some “freshness, adventure, or entertainment” in an analogy to humans. Fish don’t get the cabin fever. Some of what I stated in the prior section about the room applies to this section too. CONCLUDING REMARKS ~ Our fish have healthy water and an adequate space to swim albeit some are ready for an upgrade or would benefit from a reshuffle, it is true. I also often ask those raising the “jail cell” or “too packed” issues - do you know how fish are raised that you buy from grocery stores and consume? The fish for human consumption are farmed mostly at a 10x-100x the density of ours. Some reply we should look toward the best examples, not the worst. Agreed. But my point is: if one buys farmed fish from grocery stores, I'd not think one can in good conscience turn around and condemn what one sees here because anyone who eats the supermarket fish approves, however tacitly or not, of the farming practices. Still, there is always room for improvement in everything we do. The argument that if you can't do it ideally, then don't do it at all looks good only on paper. Those who subscribe to it, can start eating that paper to stay away from everything done less than ideally, including the food manufacture, also science, education, sports, culture, religion, you name it (well, paper manufacture is horrible for ecology too, for one), and then see how long it'll sustain them. P.S. ~ We are a DIY Public Aquarium and Rescue. These tanks too contain rescued fish available for adoption and waiting for their forever owners to come through. We adopt out. Yes, there are fees (we are not a charity and must make ends meet too) and humane keeping conditions to be met by prospective adopters.

I’m not concerned about over stocking as they look like fine no stress at all. I’m concerned for your wallet on the food bill?!

[@Fish-Story]

@@invaderjoshua6280 Thank you. The feeding is not too expensive as we over time honed the ways we get the feed. We buy wholesale NLS pellets at around $5 per lb and also wholesale frozen bait fish at around $1 per lb. All our fish cost us roughly $300 a month to feed on average. More in the summer, less in the winter.

Man.... awesome tank bro!! I once had two iridescent sharks in my 100g but within six months had to give them back to my local pet store cause they got too big for my tank lol. Same thing with the pacu I bought for my 125 gallon. He got huge! and tore up EVERYTHING! only thing he didn't do was break the glass lol. I just keep oscars, jaguars and red devils now that's about as far as i'll go. But anyway great video man and I'm glad to see your not like all the others buying fish on impulse and stuffing them all in an inadequate sized tank. Aquarium looks great and the fish all look healthy. Really enjoyed watching them man. great job!

[@Fish-Story]

Thank you for your kind review, Shawn, really appreciate it, and equally appreciate your sharing a bit of your story too. Even though this 4500 gal was more or less appropriate for each fish but altogether it was too many fish and we don't do it quite like this anymore. The water was pristine but the long-term stress from too many tank mates cannot be discounted. We did enjoy this tank too :) Nowadays the stock is roughly 1/4th of what it was.

The incoming flow at the moment is 20,000 gallons per hour. Each of the four incoming pipes has a hole where the pressure is zero or less than zero (slight vacuum) and as such the flowing water sucks in some air and delivers the water-air mix into the tank.

Do you go fish for feeder fish ? or buy them , seems like it would be very costly with so many big fish

[@Fish-Story]

I am not quite clear what you are asking but if I get it right, we never ever feed live feeder fish to our fish. 50% of our feed are pellets and 50% thawed fish. Our monthly expense for feed is around $130.

[@EvansBrosRacing]

@@Fish-Story I wondering if you go out to a river or lake and catch fish with a rod and reel or a net , to feed to yours . But it sounds like you just buy frozen ones .

[@Fish-Story]

@@EvansBrosRacing Yes, I mostly use a cast net to catch fish in the Gulf of Mexico but with the increasing stock of ours I cannot catch enough anymore and the season that's good for catching is rather short, Aug-Nov. If I had more time to fish and bought more freezers, it'd have to buy less but still, processing the fish, portioning, bagging and boxing, etc. before the freezing is also a significant effort and we are pretty much a one-man show.

[@EvansBrosRacing]

@@Fish-Story thanks for taking the time to answer , I was just thinking of 10 lbs of food at a time in just the fish portion is a lot of food and that is just the one tank . I am guessing you have many tanks . I know it is a huge job taking care of them , and so much worse for 1 person to try to keep up . keep up the good work and I am no expert but I can see that tank is plenty big enough for the fish that are in it . If the readings are good , they are fine and the back of the tank was empty while feeding until some got their food and then they went to the rear to consume their meal in peace . Some bozos are going to say stuff just to argue , and be negative , but you are respected by the majority and that is all that matters .

[@Fish-Story]

I appreciate your kind support. Thank you. Ten pounds a week in frozen fish alone is not sustainable year round because appetites vary, fish come and go as many of these are rescues waiting to be adopted into a forever home. The tank did prove to be too small for the arapaima and I failed to construct a proper home for them in time, so there is some truth in the criticism.

Such a bummer, a beautiful massive tank with even more massive and beautiful fish. Tone down the stock a ton and it will be a masterpiece. Bigger tanks don’t mean more fish when your talking about red tail catfish, pacus, arapaima and other monster fish unless it is a truly gargantuan tank. It may look “roomy” and the water may be pristine but remember these fish live in rivers and lakes. A clean jail cell with Delicious food is still just a small cramped jail cell

[@Fish-Story]

Thank you. I know where fish live, haha :) I am a professional. Do you know how fish are raised that you buy from grocery stores? 10x-1000x the density of mine. Anyhow, your logic IMHO would eliminate any and all fish keeping in captivity, or any animal keeping in captivity for that matter.

Just as one example, many fish have an ocean at their disposal but hang around one coral rock all their lives. Fish don't "think" of and don't perceive freedom and space like humans do.

[@Fish-Story]

Thank you for your interest and concern for our fish. The types of feed offered vary between feedings and even if they were the same, the fish sometimes feed, other times not of their own choosing, hunger level, and comfort or the lack thereof. Especially catfish are known to eat a lot in one sitting, then skip a few feedings. For example, the 4 paroon shark catfish have only been taking pelleted feed for us. Small TSNxRTC hybrid has been ill. Overall, they don't dig this type of feed I am offering in this video - the freshwater frozen-thawed fish. Our barramundi would never take anything but saltwater fish. Reading my comment right under the video and perhaps listening to my narration could help elucidate the issue further. BTW, there are no arowana in there but there are arapaima.

@@Fish-Story what time do you feed them with that size? Once a week?

[@Fish-Story]

In the summer once every 5 days they consume 10 lbs / 4.5 kg of herring and pellet snacks in between. In the winter the frequency can go down 2-3 times.

[@daveogmiles6152]

Are those predatory fish ?

[@Fish-Story]

Except for the pacu, they are, some more some less. RTC are more opportunistic than predatory in the wild, I'd classify, same with the jau.

How do you heat this aquarium? I am planning to get a 600 gallon one but if I heat it with the conventional method, it will consume a lot of electricity. Is there any alternative method of heating a large aquarium with the least operating cost? Let it be expensive to install but I want less expense in the long run.

[@Fish-Story]

We don't heat our tanks, almost never. We live in subtropical climate and get away with having curtains on our pavilion walls. When it gets too cold, we lower them. What you probably need to do is insulate your tank from all the non-critical sides, that is al sides except the main viewing pane and perhaps the top. Or you can build a tent / pavilion / greenhouse type structure over your tank if it is not indoors in addition or in lieu of the insulation.

[@Someone-zx7xd]

@@Fish-Story But I live in extreme climatic region where winter temperture can get as low as 2°C and summer can get as high as 35°C. I want to keep the temperature constant at 80°F(26.67°C). What wattage of electricity would be required to raise the temperature from 2°C to 26.67°C in a 600 gallon tank? It looks insane to raise that much temperature in such a large volume of water. Do you have any info about it?

[@Fish-Story]

The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C. 600 US gallons x 3.785 l/gal = 2,271 liters = 2,271 kg of water... x 4,200 J/kg°C = 9,540,000 J/°C to heat 600 gal by 1 degree C ... x 25 °C = 240,000,000 Joules of energy to heat 600 gal by 25 °C. 1 Watt = 1 Joule/second. 1 KWatt = 1000 J/s. 1 KWatt-hour = 1000 J/s x 60 minutes x 60 seconds = 3,600,000 Joules. 240,000,000 Joules / 3,600,000 Joules = 66.2 KWatt-hours... at, let's say, $0.10 per kWatt-hour = $6.6 dollars to heat 600 US gallons by 25°C by electricity (gas is usually cheaper). I don't know if this helps you or not but feel free to ask more questions. People have built tropical fish tanks in temperate climates, e.g., Ted of anythingfish.com built an 8,000 gal tank in Seattle, which is covered with snow in winters but if you insulate it well, it should be doable.

[@Someone-zx7xd]

@@Fish-Story Nice to know that you are not irritated by questions and answer kindly.

[@Someone-zx7xd]

@@Fish-Story But insulation is not an option because I am keeping the aquarium at the centre of the room and thus it should be viewable from all sides. It's not a problem to raise the temperature at once but it is about retaining the temperature. I am just asking about the wattage of heater that would be required to keep a tank of 600 gallon consistently at 80°F if the surrounding is at 2°C(35.6°F) and there is no any kind of insulation. Will 3 kilowatt of electricity be enough to retain the temperature at 80°F? It should also be noted that as it is a large volume of water so there should not be much heat loss because the ratio of "surface area : volume" would be lesser than that of a small tank.

[@stevenphelps7929]

What about the pacus?

[@Fish-Story]

They get the pellet feeding. They steal fish too when they can.

[@justinthomas9119]

That looks so overstocked

[@Fish-Story]

Thank you. Some think so but the water is well aerated and pristine - ammonia zero ppm and nitrite zero ppm by an API liquid test kit - and the fish are usually healthy. I've been having a problem with columnaris but it was brought into the system with new fish from the wild, my error, and I don't believe it has to do with the bioload. The biofilter for this tank is 15,000 gal.

Thank you. Yes, these were the free loaders from the koi pond. I usually feed them whole salt water thawed fish - herring, mullet, jack, snapper, pompano, etc. This is my first try to film feeding this tank. Next time I will try their usual. It should be more entertaining.

[@goblinslayer1115]

I got a question how are those fish all comfortable with each other since they are so big?

[@Fish-Story]

Of course they are not ideally comfortable. I believe most are adequately comfortable, because they exhibit good appetite and natural behavior. Arapaima are an exception to this statement, as the time after this video had shown. They outgrew this tank and kept jumping out of the tank, eventually killing themselves. I failed to build their future home quickly enough.

[@Fish-Story]

When it comes to frozen fish, I only ever feed marine bait fish to mine. They do take a fair share of pellets, so I don't know what would happen if the diet was exclusively marine fish. In general, it is prudent to stay away from extremes and offer different types of feed with balanced nutritional value. Having an all-inclusive pellet to be a large part of the diet enables to feed many other things too.

I feel sorry for the big catfish that are so blind and just feeling for the food with their whiskers. I would make sure they are each fed first just because they are so blind.

[@Fish-Story]

Thank you. They all are well fed. Moreover, they are quite well suited for their life both in the wild and in captivity. Poor vision that some of them have doesn't keep them from feeding well. Most catfish have an ok or a good vision. The barbels give them a huge advantage over the diurnal fishes in the dark but also are a great sensory organ to use at all times.
