I have a 39 gallon with 20 gallon sump and im considering getting a melenarus wrasse. Ive been told they do great in a 40 gallon. I only have 2 other fish and they are both ocellaris clowns. Will the hoeven's wrasse (melenarus) be good in my tank? I have no shrimp, just snails and hermits. I do however have plenty of rock and coral. Heres a real recent pic of my tank.
