Added the Siamese Fang Blenny to my 50-gallon reef tank last month. It’s very active and swims freely in open water, not clinging to rocks. The fangs are harmless and it doesn’t interfere with other fish. Feeds well on mysis and brine shrimp. A great addition to a peaceful reef setup.

This blenny is a standout in my tank. It moves with a unique hopping motion and looks elegant. I was worried about it being eaten by larger fish, but it’s safe with my tang and wrasse. Easy to care for and very peaceful.

It’s a beautiful fish with a distinct appearance. Feeds well on a mix of frozen foods. A bit shy at first, but settles in quickly. Works well in a reef tank with other small fish.
