can i use two 5watt led lights in my planted fish tank instead of a single 10watt light? will those 2 work same as a 10watt light?

[@patriciaproctor4175]

Thank you for this. 2 out of my 9 aquariums every time I turn the lights on they freak out and go hide. So I find myself not turning it on cause i don't want to stress them out. The room they are in gets plenty of natual light.

[@samsadowitz1724]

I am keeping some fathead minnows that I am going to use for bait and this happens every single time I turn on the light on the thank they are being held in.... needless to say, I leave the light off on it all the time

[@pyramid992]

I found my barbs doing this in my 20L and I basically did some exposure therapy, where I placed extra light on the side of the tank where they hid and I would do this for about 30 to 40 minutes only. Then turning those extra lights off will make the fish feel less intensity. Now my barbs have no problem with the regular aquarium light.

Another great video. I've actually had the pleasure to see bettas in the wild. While they are in shallow waters, that water is covered with a thick layer of floating plants. So, they don't get a lot of light in the wild either. My other plants don't like it much, but I cover my aquarium surface with duckweed and frogbit. My betta loves it!

[@finnwiggles28]

Love that you're talking about what life is like from the INSIDE of the aquarium. The fish have to live there, I have lushly planted tanks and only turn the lights on for a few hrs of the day while I'm enjoying my tanks.

[@dylantan4245]

The main reason we keep fish is to enjoy their beauty. An aquarium, imho, absolutely needs a light. Tried lightless tanks and tanks with different types of light. Best colours on the fish come out in a tank where the lights turn on and off on a schedule, fish’ll adapt to light accordingly. Of course don’t get a super blinding light.

[@gabrielweedon7233]

I personally disagree with the idea that aquarium lights are for our enjoyment only. I definitely agree that having lights on makes an aquarium look better. However, like humans I’ve observed that fish too have a circadian rhythm so when I turn off my aquarium lights, whether it be freshwater or marine, my fish will go into their holes to sleep or float in the open water column and they either won’t come out or you’ll barely see them at all until I turn them back on. I think lights in an aquarium help to regulate a fishes circadian rhythm. That is, if you switch them on and off at roughly the same time. Love your content guys, keep it up!

[@vorsntioedits301]

Same here I turn my lights off and all my fish just swim to there sleeping spots

[@gabrielweedon7233]

@@vorsntioedits301 It definitely makes sense too. In coral reefs, it appears like a desert at nighttime. I assume evolutionarily speaking it’s because mating behaviour for most fish doesn’t occur during the day so there isn’t anything to do, most fish aren’t equipped with nighttime vision and of course predators hunt at nigh so hiding is the most viable option for most fish.

[@dusk1947]

That entry disclaimer is crucial, this is a fish only discussion... My coral tank needs a very good light, and my planted tank has descent ones too (though no where near as strong as the marine light). This topic depends on the Biology in the tank. This discussion changes dramatically when you introduce sensitive photosynthetic organisms. But, in the context you represented this: Totally agree, nice video. I also like how you framed the difference between high-light and low-light aquarium plants, as most of the hobby's current list of plants are low-to-moderate-light plants. Very few are true high-light plants.

[@billbillinger2117]

I found a 48" Fluval Aquasky light for 40% off at my local Fish store. I scooped it up for my 75gal Mbuna cichlid tank and they seem to love the natural day night cycle. And I love how the new light seemingly makes their colors pop a lot more than my old standard light. Oh and I don't have much ambient light so without a tank light it would be almost un viewable.

I beg to differ. Bettas prefer the weedy edges of ponds where the light is not as strong. The water is not muddy. There are videos that show this clearly.

[@asianaquatics3719]

In bettas they actually love dark water, indian almond leaves would be great it promotes coloration and health of betta. You can have them in dim light or natural light like in the morning. Just the right amount of light to see the fish.

[@AdreaRaptorX8]

Another thing to realize about lights is how much heat they produce. I have leds but they still put out a lot of heat which can make the tanks run warmer.

[@seansquill8773]

I keep a lot of Severums and Geos and I only have my LED’s on for about 3-4 hours in each tank daily, and they aren’t kept to bright at all. I mostly put them on at night to observe them, and when I turn the lights on they absolutely know it’s time to eat. However since both tanks are fairly close to a very large picture window and from sunrise to sunset they are getting a good amount of light throughout the day. By the time 10-11pm comes around they are fairly relaxed and ready for sleep👌🏼

I know this video has been up for months now, but I just saw it today. My question is, about the submersible pumps that has RGB light built on it, is that ok for the fishes? It's not that bright at night when the main light is off, its just that, there is no switch for the RGB to turn off. Its like having a small night light. Is it ok for my fishes (tetras, danios, angels) or could this stress them out? They seem happy at very active whenever I'm around and when its feeding time as well.

[@Soliloquist24]

My female Betta and 7 Harlequin Rasboras seem to actually prefer the lights on. It has dozens of color combinations and I can adjust the brightness enough that I can make it super dim to keep the fish comfortable. Also, the second I turn the lights off, my Betta starts chasing all the Rasboras and stressing them out. I have plenty of areas in my tank for them to hide and get away from the light, but I can tell they get noticeably stressed when I turn the light off. Debating if I should even just separate them and put the Betta in her own tank.

My Oscar tank is in the basement where there are no windows, so the room is totally dark. Shouldn’t I turn on the tank light in the morning and shut it off at night to simulate the cycle of light in nature? I read that fish’s health can be affected negatively if the tank is totally dark most of the day. In other words, it affects their growth hormone, mood, brain and nervous system. Or can I just turn on the tank light in the late afternoon when I get home from work and have it on for 3-4 hours until bedtime?

I'm having an issue with my 10 Celestichthys Choprae. I got them about a month ago and WOW they are gorgeous. Well I quickly noticed that with the lights on the colors become muted and they stop being active and don't even eat very much which concerns me because they're known to be voracious eaters. With the lights off all night, then turn on in the morning. It takes about a minute from them to be fully colored up and super active which is normal for this fish, to moving slowly with fins clamped and colors faded. Blue light seems to help some but I've also heard that blue light can cause more stress. Can anyone with experience with this fish give me some advice? They ate so unbelievably gorgeous and it's a shame not to light them up, but when I do the colors fade. To be clear these are glowlight danios...NOT genetically altered glofish. These are all natural and come from Myanmar

My tanks are in my dining room, with windows on 2 walls. I rarely turn on my tank lights. My fish are just fine, breeding and dripping fry regularly.

If you keep tinfoils with other fish like oscars and parrot fish, light is a necessity. Tinfoils as they grow start splasing water and they do that when they dont get minimum hours of lighting. In my tank a minimum of 2 hrs in the morning and 2 hrs at night keeps the tinfoils calm and they dont splash water. Also I think, the light might do something to the aquarium bacteria and algae.
