Rainbow Shark TipsRainbow Shark Profile
I have a gorgeous rainbow shark! He is fine with all my other fish - 2 clown plecos, guppies, one adult and about 20 babies and 6 danios. Feed them shrimp as well, not brine shrimp just normal shrimp from the supermarket. They love them and it brings their color out!
My Rainbow Shark always jumps out of the tank. Once he was almost rock hard after being out of the water all night and I put him back in and he survived.
I have had my rainbow shark for almost 2 months, and it is getting more aggresive. It does not like my tetras that I put in the tank, and it keeps trying to attack them.
Why do these fish have to be kept in such a large tank if they only grow to be six inches long? I have 29 gallon tank with a sailfin pleco and 3 bleeding heart tetras would this fish get along with them?
|Rainbow sharks are very active swimmers that need more open space for swimming and to limit any territorial aggression that may crop up. Theoretically, this mix of fish should be ok... The pleco will handle itself well and the rainbow should leave the tetras alone. Also, the sailfin pleco is going to get too big for a 29 gallon tank. Time to get a bigger tank. More tanks - woo hoo! :)|
Hi. I'm a newbie and recently started a new aquarium. I started with a rainbow shark and a betta fish. They started off fine together but now the rainbow shark is showing signs of aggression by chasing and nipping the betta's fins. Help?
|Obviously, you need to separate these two fish by using a tank divider or return one of them to the store. Rainbow sharks can get aggressive with their tank mates, especially in smaller aquariums with cramped conditions.|
I have two redtail sharks and one rainbow shark, with three tiger barbs, three black phantom tetras, and three bleeding heart tetras, a small plecostomus and a molly. The different sets of tetras and barbs school together (three schools) and the sharks don't bother them. The molly is big enough that they don't mess with him, and the plecostomus is always on the floor and isn't much bothered either.
One way to keep them from jumping out that I have found helpful (after having one rainbow jump out) is to float a bunch of plants (fake or real) on the top of the water. It seems to serve as a ceiling that keeps the sharks lower. Hope this helps.
I haven't had a fish tank for long, as we got it when we recently moved home. We were told by the store all the fish we had together were ok together, we got guppies and a rainbow shark. Recently one of the guppies was found dead in the tank and I'm noticing that every day a few of the guppies tails look like they been nipped at. Do you think it could be the rainbow shark doing this? I also wanted to know if the light need to be kept on at all times?
|Depending on the tank size (cramped confines can lead to more aggression), it could be the rainbow shark doing the nipping or even the neons or other guppies. Watch them closely and take corrective action if needed. You may want to invest in a tank divider or remove the rainbow shark (if he's the culprit).
You definitely want to have some down time with the lights off for your fish. Please read the aquarium lighting article for more information.
I've had my rainbow shark for over a year now, originally in a very small tank with platies, tetras and gouramis. That didn't go so well so we moved him into a tank of his own until we could afford a bigger tank. We've now got that and had him in it for nearly a year with zebra loaches, cory cats, and a whole bunch of different tetras. He is territorial and will chase others out of his hiding holes and away from what he deems as his food but that is as far as his aggression goes. He really is a delight to own.
I've had my Rainbow shark for 3 years. I had him by himself for the longest time, but now have him with Tiger Barbs and Rosy Barbs. He does get cranky with them, but they out swim him and they leave each other alone for the most part.
I have an amazing Rainbow Shark. He lives in my 30 gallon community tank, in a hollow log. He makes a game of chasing the other fish, especially light colored ones! He was really small when i got him (less than 3 inches. He is absolutely HUGE now - 7-8 inches! And amazingly last month marked 8 years that I've had him! I never see anyone who has one this old! About 4 weeks ago I had a big scare. While cleaning his tank, I walked across the room and he LEAPED out of the tank and fell to the floor. He tore off the entire upper part of this tail fin and had several scales damaged. When I put him back in he was floating on his side. I treated him with Melafix and Nitrofurazone - changing water every other day - and 4 weeks later he is swimming around, chasing the fish as always and his tail is starting to grow back! He's a tough old guy! What a great fish.
We have had our rainbow shark for about 2 years now. He is fairly aggressive with our other fish so we finally bought a divider for the tank. We put the shark and the barbs on one side and we keep the milder fish on the other side. So far this process is working out very well. Occasionally some of the smaller fish get over to the "aggressive" side of the tank and we just rescue them and put them back over on the "passive" side of the tank.
