I have a 30 gallon bowfront aquarium set up with 1 rainbow shark, 1 Convict cichlid, and 6 Tiger barbs as well as a Electric Orange Crayfish. MY Rainbow shark is constantly chasing around my tiger barbs and is causing issues, I am considering taking him back to the store and possibly purchasing a new fish. I want a bottom feeder that will grow to be about 4-6 inches that has nice colors and isn't aggressive. Any thoughts will do, please and thank-you.
