i have possum wrasse, and ive tried to get him to live with another of his kind but he only fights with other possum wrasses. would he do this with other types of wrasse? because id really like other wrasses in my tank.
You wont be able to put 2 possum wrasses together in a 30. Ive got a 100G, i put both my wrasse in at the same time (a 6line and banna) and they still fight on occasion. I dont think you would be able to put another wrasse into that tank.
