I currently have a sea cucumber in my 75g that I'm downsizing to 32g. I don't know what kind it is... something from the Caribbean, about 5 inches long when not stretched out. I've had him since the birth of my reef in 2014. I'd hate to leave him behind, but want to be sure the new tank can sustain him. IF I move him in, he would be the last to move. But does anyone know if he could make it in a tank that size?
