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

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.
