What depth sand bed do the wrasses require? I also have a rimless tank.... I heard wrasses can tend to carpet surf.
Melanurus has a small tupperware in the frag tank with sand to sleep in. They can be trained to sleep in there. Its about 2 inches of sand. My frag tank is open top and have 4 wrasses in there. None of them have hopped. The melanurus is the only one that doesnt freak out if I drop something in the tank or pass it. So they are less prone to jump imo. They have great personalities.
