I’ve kept the Sandhopper Blenny for six months in a 30-gallon tank with live rock and corals. It’s active and doesn’t damage the reef. It spends most of its time near the sand bed, which is a nice behavior. Only a bit territorial during feeding times, but overall it’s a good addition to a reef setup.

The blenny is easy to spot and active in the sand. It doesn’t eat corals or disturb the inhabitants. I noticed it’s more active at night. I’m happy with the compatibility and care level.

This blenny has been a stable part of my tank for over a year. It’s not overly aggressive and coexists well with other fish. The mature size is manageable in a 30-gallon tank. Great choice for intermediate reef keepers.
