Smith’s Blenny (Live Aquaria)
The Smith’s Blenny is also referred to as White’s Blenny, Smith’s Blenny, White Blenny, or Disco Blenny. Its body is mostly blue with a black stripe that starts at the chin and runs through the eyes and down the dorsal fin.
It thrives in an aquarium with live rock in a 10-gallon or larger tank. The live rock offers hiding spots and hunting grounds for small crustaceans, which form part of its natural diet. It is generally peaceful and only becomes aggressive if tank mates have similar body shapes. Its fangs are primarily a defensive feature used to deter aggressive fish.
Diet includes chopped crustaceans, vitamin-enriched brine shrimp, and frozen herbivore food.

Added a Smith’s Blenny to my 15-gallon tank with live rock. It’s active and stays in the crevices, which is perfect for a peaceful community tank. Feeds well on brine shrimp and chopped shrimp. No aggression observed so far.

The blenny looks great with its blue body and black stripe. It hides well in the rock and only comes out when feeding. I’ve noticed it’s more active at dusk. Feeding it a mix of frozen and chopped food works well.

Easy to care for and very calm. It doesn’t bother other fish even when they’re active. The live rock setup makes it feel at home. I’ve been feeding it brine shrimp and a bit of chopped crustaceans weekly.
