HELP! MY RAINBOW SHARK IS AGGRESSIVE AND tRYING TO NIP AT ALL MY TANK FISH!

[DWN MARIE]

I took him out and put him in a 10 gallon tank. I am researching and need to put him in a bigger tank. What kind of fish is compatible with this psycho shark?? He's killed a few of my fish that are in a 75 gallon tank.

Generally Rainbow Sharks like to choose and defend an area of the tank against bottom dwellers. They, in my experience, generally leave mid-top dwellers alone.

Yeah my rainbow shark can be fairly aggressive to other tank mates but has never gone to the point of killing a tank mate... I'm afraid that you need to rehome your shark as once a fish has become aggressive there is not much that you can do to make them less aggressive. Either try to rehome him or set up a separate tank for him. Hope this helps.

I have an Albino rainbow shark. Prob about 4-5in he's in a community 55. With a whole lot a stuff. He chases around like everyone of em. Never seen him nip though, only "mess with". He constantly does it but only in a playful seeming manner

My Rainbow shark pretty much leaves everyone alone as long as they don't try to get into his cave.

What fish was he with when inhabiting the 75g?
