Dorothy Lyman –
Easy to care for and very peaceful in my 30-gallon reef tank. It’s active but doesn’t bother other fish. Grew to 3.2 inches after six months. Perfect for beginners.
Joanne Langdon –
Added this blenny to my 24-gallon tank and it’s been thriving. It doesn’t eat corals and stays near the substrate. A good choice for a calm, colorful addition.
Amanda Chapman –
First time keeping a blenny and this one is a hit. Very active, doesn’t stress other fish, and fits well in the tank. Grew to 3.5 inches in about a year.
