Right now I've got a bristleworm problem in my reef tank. Even after after moving it down 3 floors and in the meantime attempting to murder every single worm in the tank, theres still tons of them. I've looked into different ways, I got a trap which works to get some of them. however, I want some fish that could also help out with this, and so I looked into one of my favorite fish, the bicolor goatfish. I've heard many times the minimum tank size for them is 50 gallons. The tank is between 45-50 gallons, I think its 47 or something, with a good amount of shelter and at the same time swimming space and open sand. Would this or any other type of goatfish work?
