I have melanarus wrasses in two tanks, and the one in the 20 gallon that I got to deal with bristle worms didn't make a dent in the worms, and if now harassing the smaller fish in the tank ( a pair of mocha clowns, two PJ cardinals ans a bicolor dottyback) The larger wrasse is in a 90 gallon tank with a pair of Clarkeii clowns, a large desjadini tang, a sizable yellow tang, an equally sizable blue hippo tang, a coral beauty, a tiny 6-line wrasse, a lawn mower blenny and a small blue chromis. I have a 32 gallon tank with a pair of gladiator clowns, a blue hippo tang, who is outgroing the tank, a huma huma trigger that is also probably outgrowing the tank and a orchid dotty back. Where is the best place to move the melanarus wrasse from the 20 gallon?
