The Glass Blenny is active and curious in a 40-gallon tank with plenty of rocks and sand. It doesn’t bother other fish as long as the tank is large enough. I feed it brine shrimp twice a week and it seems to enjoy it.

It’s a good addition to a larger saltwater tank. I noticed it hides under rocks during the day and becomes more active at night. I had to remove a small goby after a few weeks, but it’s not a major issue in a spacious setup.

The blenny is fine in a 30-gallon tank, but I saw it chasing a dartfish. I now keep it in a larger tank with more hiding spots. It’s not aggressive, but space matters.
