Sandhopper Blenny
The Sandhopper Blenny, also known as the Red Stripe Sand Perch, originates within the rubble zones of the reefs in the Indo-Pacific. They have an elongated body that is vertically striped in alternating red and white. The head is accentuated by large eyes, which are black in color. These fish are very hardy and do not require a large aquarium.
A well-established 30-gallon or larger aquarium with plenty of live rock is a suitable environment. It is not usually aggressive, unless the tank mates appear to have a similar shape as it does. It is best to house singly unless kept in a larger aquarium and the two are a mated pair. The Sandhopper Blenny is a great jumper, making a tight fitting canopy a must.

Easy to care for and very active in the tank. The red and white stripes stand out well. I kept it alone in a 40-gallon tank with live rock and it’s thriving. The canopy fits perfectly and prevents it from jumping out.
Tim McDonald –
Arrived healthy and quickly adapted. Not aggressive and doesn’t bother other fish. Only issue is it jumps a lot, so I made sure the tank has a secure lid.
Carl Mitchell –
Great addition to my reef tank. The fish is colorful and active. I’ve had it for three months and it’s still in great condition. The live rock setup supports its natural behavior well.
