I’ve had my Molly Miller Blenny for three months now and it’s been very active in the tank. It doesn’t bother the corals and seems to be adjusting well. The tank is 30 gallons and the water parameters are stable. It’s a good addition to a reef setup.

The blenny is semi-aggressive, which I expected. It doesn’t attack other fish but does defend its territory. I keep it with a few peaceful species and it’s not causing any issues. Water quality is key, and I’ve been testing it regularly.

Great fish for intermediate reef keepers. It’s colorful and active. I noticed it spends time near the rockwork, which makes it easy to spot. I’m happy with the size and behavior in my 24-gallon tank.
