I have a very small 6 gallon nano frag tank. There is a two inch elbow PVC pipe in there for surface area, and for a hiding place for the fish. It's against the back wall. There's no sand, and no live rock in the tank.
Do you think that a Pygmy Possum Wrasse will live comfortably in the aquarium? No other fish will be housed.
