Got this little guy on 06/29/16, what a fun little fish he zooms all around the rocks, has gotten a really fat belly on him now and he is fast as lighting. This is a nice addition to my tank and I enjoy all his personality. FYI he really enjoys copepods!!! so you might add some if you don't already have them.

Tiny lititle guy, but fits right in. Will hopefully help the rest of the clean up crew I employ to keep my DT looking as best as possible with as little extra help from me as needed. I like to let nature work on my side.

Algae eater! Before I added my Lawnmower, my tank had waves of green hair algae. He took to task immediately- transforming my tank back to the clean look it had in the early stages. I have never seen him eat the prepared foods I put in the tank for the other fish, it appears to me he only eats the algae growing. In addition to his functional nature, he adds a lot of character to the tank-as he perches, hops and stares at you with this cartoon look. The only knock I have on this guy: he is currently chasing around my new Clown Goby, who also likes to perch in the crevices of rock. Otherwise, he has been a perfect tank mate to the others and even survived a bully clownfish I had, who killed 5 other new costly additions. I guess the Clownfish couldn't get to the blenny in the rocks and gave up. Quick Summary: This is a very cost effective and easy fish, that should be considered a staple in any tank.

Took to tank immediately and started munching on the rock for after about 2 weeks he has really developed a personality and is quite the character...he still eats on the rocks some but mainly swims to the front rock when I walk up and sits there watching me and waiting for the flakes and mysis to get dropped in. Probably the most "intelligent" fish I've owned...he already knows the schedule and recognizes the difference between me and my wife walking up to the tank...she doesn't do the feeding and he ignores her!

I love my Blenny! He took to my tank like a fish to water (I know, that metaphor is compounded) and he has been fat and happy ever since!
