Grumpy Rainbow Shark

Stupid starter aquarist I was two years ago got a rainbow shark for a community tank. Well, this sucker got pretty big and he is NOT nice. I know they are on the aggressive side but he's injuring fish now and even nips at me when I clean the tank. I can't keep him in there anymore it's not fair to the others.

I have another tank with a convict a #firemouth and two tiger Oscars. The convict is also super aggressive and the Oscar's are lazy and docile. I think they are probably about 8 inches. The shark is 3+ inches. I'm wondering what the likelihood is of them surviving together. The tank they are in is a 75 gal and I intend on upgrading that this summer to a 125 if possible.

Before y'all start coming at me for mismatching fish, I KNOW now. It's a learning process, for everyone.

 

No need to apologize for keeping a mixed bag of fish. Lol.
I think it would be a good idea to move the Rainbow Shark over to the big boy tank. Be sure to rearrange the hardscape as to afford plenty of hiding spots for the new guy.

I've got quite the assortment

Thank you. I think that's what I'm going to do. Maybe I'll just monitor and if it doesn't work out try to rehome. Hes a beautiful shark.

Photo of beautiful shark?

 

I think you will be using the Rainbow Shark as a feeder fish.

Would it not be less cruel to rehome it?

How can you monitor it when its likely to be swallowed?
