Overstocked or Just Right? Top 10 Beginner Saltwater Fish & Stocking Tips! - Ep: 31b

[@Baka_Mop]

I remember reading someone's post on the forums about fish stocking, and it made me laugh. They said, "If you follow everyone's advice on the internet, you'd have a 120 gallon tank with 1 goby and be doing water changes every 2 hours."

[@juliekernahan9480]

I have a 30 gallon innovative, 2 clowns ,yellow watchman with pistols shrimp , bengel, algae blenny , and last my six line wrasse , all work well together .

[@lionfishlair5215]

That's an awesome selection!

[@hokuk9training970]

I love your tank selection! This is pretty much exactly what I want to do. Do you feel like your bengel is okay with just one or do you need two? I would love to just get one but heard then need to be in groups?

[@jerrislittlereef4023]

Matthew please do a stock list for newbies with larger tanks like me. I have a 115 gallon tank I'm setting up.

[@chopers49]

Currently have a 150 gallon stocked with 3 blue/ green chromis, 1 Bicolor Chromis, 1Talbot damsel, 1 Coral Beauty, 1 Long Nose Hawk , 1 Flame Hawk, 1 Diamond Goby , 2 Black Storm Clowns, and 3 Mocha Vincci Clowns.... I pray to God they all stay happy and healthy! I'm in love with this new part of my life. Now I have to focus my husbandry before I add any other fish! 😍

[@freakygoblin3068]

I know you mentioned it with the 6 lined wrasse but to highlight, it's generally recommended to add in order of peaceful -> semi-aggressive regardless of fish types. It's useful therefore to build a stock plan. Plan and research before shopping and once again.. no impulse buying. Should be noted the more "hiding spaces" in your rock work the more likely the fish are to come out of hiding as they feel safe. Chromis are hit and miss from what I've read. Loads of stories about starting with 3-5 and ending up with 1. I'd probably add an algae eating blenny, such as a Starry Blenny ((Salarias ramosus), to the 30g+ stock lists but they are one of my favourites anyway because of their character so I am biased.

[@dr.mahera9284]

No orchid dottyback and purple firefish together..the pseudochromis likes to go after similar looking/colored fish and it wont end well for the purple firefish..other than that the list looks great..

[@jessawyer77]

New to saltwater, but very experienced with freshwater so I was prepped for cycling, bioload, etc. I have several of these beginner fish. Annnddd then added a blue spotted puffer. It was an impulse buy because my girls loved it and it's been working out so far! Everyone seems to be getting along and sharing food peacefully. The only traumatic event was when I thought the puffer was dying the second evening when it changed color, curled up against a rock, and started bobbing when it went to sleep. 🤣

[@bjmarchives]

You nailed my 20g stock list

[@paulshockley8632]

Hey, to be clear is that what you have in your 20 gallon tank? 5 fish? Just wondering as I have a 20 cube and have 3 fish and would like to max it out too

[@PSEsq]

My six line wrasse killed about $200 worth of fish. If you get one, which can be a nightmare, try adding it last. But, I doubt that will even work. I had to move mine permanently to my coral quarantine tank because it doesn’t play well with other fish. It is in there with a damsel. They are both jerks, so they seeming to get along together.

[@Marvel_vs_Capcom84]

My 6 line wrasse has been very peaceful so far in my tank.

I'd swap in a tail spot blenny! One of my favorite fish when I had a 20L nano tank back in the day.

Everything seemed spot on, except for the Sixline. I'd replace that with a yellow Coris Wrasse.

[@eeveekyu4446]

before watching this video I was actually planning on getting my first tank and my plan was a waterbox 20G with 2 clownfish, royal gama basslet, firefish goby and a skunk cleaner shrimp but I was unsure if that would be to many. your recommendation is perfect thank you!!

[@eeveekyu4446]

what order would you put those fish in?

[@BulkReefSupply]

Firefish tend to be the most timid, so it wouldn't be a bad idea to add that fish first. From there, flip a coin on the Royal Gramma or two clowns. I don't think you can go wrong either way 🙂 The cleaner shrimp can be added at any point once the tank is cycled and there is no ammonia present.

[@eeveekyu4446]

@@BulkReefSupply thank you so much

[@fuffoon]

I had a 20 gallon with about one hundred fancy tail guppies. No, it was not marine, but it was still impressive. I destroyed it when I augmented the filtration. The Juwel Bioflow 300 was doing perfectly. Now I'm restarting my 710 liter and plan about 6 or 7 fish. I used to love heavy stocking but chasing nitrates is no longer fun with three ruptured lumbar disks, although my wife bought a 114 liter carboy with wheels for me. That thing really makes a difference when moving water.

[@EJGraham14]

I think stocking just equates to how much work you want to do. Also the compatibility of the fish.

[@etrigan1976]

Got a Helfrichi Firefish. Beautiful fish. Was a shock to watch my tailspot blenny attack and almost kill it and then my coral beauty finish it off on day 2. Whole thing from first attack to dead fish took 15 seconds.

[@chrismetalwilson2588]

Awsome advice wish I would have waited to get my baby six line wrasse. I've had mixed now for two months he's about 2 inches in length but absolutely no aggression towards my fish or invertebrates. I also have a coral beauty pigmy angelfish a lawnmower blenny a bycolor blenny and a blue velvet damsel in my 55 gallon tank

I had a really picky eater citron goby. Really good video! Gotta stock up my 75g!

[@BillFarrellOnline]

I'm glad I came across this videoo series. I'm getting ready to start up a new 40g tankl from RedSea and was having a hard time trying to settle on a set of fish.

I was also thinking about a Dragonet instead of the Chromis.

[@jairocampos2584]

Wow another great video

[@tmac1072]

I ran into Uronema trouble trying to add several blue-green chromis, but wound up with a sole survivor who has done great. Might I suggest some Springer damsels as an alternative? They're pretty peaceful and really add some nice blue pop!

[@pamelajohnson6425]

If I'm following the 40 gallon stock list, but don't want to get the six line wrasse and the chromis, what can I replace them with?

[@joshua_w]

Decora goby is a name. Decora (dee-core-rah) comes because its the latin sp. Name.

[@BiologyIsHot]

A great alternative to the purple firefish is the exquisite firefish. Pros: 1) even better coloration (the white area on them is slightly yellow) 2) they are from deeper waters than purple firefish and I find that they do not jump at all if you have issues with that (although get a lid anyways) Cons: 1) much pricier 2) they are from deeper waters and they tend to hide/live deeper in the rocks than your average firefish. I have one that literally burrows underneath my rockwork in the sand every night about an hour before lights off until morning.

Everyone seems to be doing great! Been about 2 weeks all together. We run a quarantine with Copper Power at >2.0ppm for at least 30 days before acclimating into display tank. Also did a 90 day fallow period on display before adding any fish. Things are good. I would love to get an angel to add to the tank, just not sure how it would change the dynamic. We love the yellowpeel angel, and coral beauty angel. Any recs?

Almost all Angels have at least some risk of being coral eaters, but one of the other common ones in reef tanks would be the flame angel.

I like this video because I feel it's given me permission to add eight fish to my 30g long aquarium. However, I keep hearing that if you add three Banggai Cardinal fish, two will pair up and kill the other one. I've also heard of Flame Hawkfish killing shrimp gobies.

[@BulkReefSupply]

The big key to keeping the peace is often feeding. Feed small, but frequent meals throughout the day and you'll likely see less aggression in the tank overall.

[@PhiCongDoan7587]

I actually have 3 pj cardinals and they've been together since day 1 when I moved from a 45 to a 75g. And according to my research if the hawkfish was first put in and established he will eat shrimps. So probably try having an established shrimp in first before the hawkfish! I love the red hawkish they are so comical.

[@thechickenwizard8172]

I'm working on setting up a macroalgae tank, though haven't secured the actual tank yet. I'm looking at either a 10 or 20 gallon, but the stocking would be pretty much the same either way: 1 ocellaris clown, 1 rainfords goby, 1 yasha goby and 1-2 tigrigobius multifasciatus. Do you think this selection would work fine in either size, especially since it'll be macroalgae dominated?

[@lionfishlair5215]

That sounds like a good selection. The only thing I would worry about is keeping two different gobies in the same tank, many people believe this is a big no-no and can cause aggression and in-house fighting between them. However, my friend kept a watchman and fire goby together for many years, and they got along perfectly fine. I suppose it is just dependent on the individual fish, your aquarium stocking, and the size of your tank. Good luck dude, I would certainly recommend the 20 gallon tank as well 👍

I'm thinking pair of clowns, pair of goby and shrimp, 3 cardinals, 1 six-line wrasse, and a dwarf lionfish. Noted that the lionfish may predate on the cardinals or even the clowns, thats why I'm planning to start out with a small or juvenile lionfish and add him lastly in the stocking lineup. Will just let them be "friends" with the other inhabitants as he grows. Is this doable?? I've seem success with this set up tho. In which the lion doesnt bother its tankmates and cares only to the new things that fall into the tank. What do you guys think? Do you guys have any suggestion in terms of centerpeice fish?? Other fish in mind are: toby/saddle puffer or small type of tang (?)

We're talking about a 20 gallon aquarium before rock/sand is added. A standard 20 gallon is generally 24" x 12" x 16" or a 20 long is usually 30" x 12" x 12". Don't overthink it too much 🙂

[@BulkReefSupply]

As long as there is enough habitat in the tank (i.e. rockwork) to give the fish places to hide and your filtration is capable of taking care of the fish waste, you should be just fine. Of course, keep an eye on the tank and look for any signs of aggression.

If you use the 40 gallon stocking list, you'll be in a good place. From there, you can probably add one or two more down the road as you learn the ropes and see certain fish species that you really like. You might even be able to add a small tang like a kole tang. if this is a 4 foot long 55 gallon.

[@Brock0122627]

Do you have to introduce them all at once or can you slowly add the fish? 40 gallon breeder tank here

[@bangmonsta]

slowly, in batches, from the least aggressive to most aggressive. This way, your peaceful fish have time to settle in, and your biological filtration has time to grow/adjust to the new bioload. Maybe do something like this - divide your stock into 3-4 batches, and wait at least 2 weeks between each batch.
