This blenny is a fun addition to my 40-gallon reef tank. It’s active and always moving, chasing food around the tank. I love how it adds energy to the community. It hides well in the rockwork and doesn’t seem to stress other fish. Great for a dynamic, lively display.

The coloration is quite striking with the dark bars and brown spot on the gill cover. It’s active but not overly aggressive. I’ve had it for three months and it’s still healthy and curious. Needs a good hiding place, which I’ve provided.

A real highlight in my aquarium. It moves quickly and seems to enjoy the feeding time. The tank has plenty of rock, and it uses the crevices well. I didn’t expect such a lively fish, and it’s definitely worth the effort to set up a proper habitat.
