Lawnmower Blenny Owners

[tigereye37]

I picked one up about a month and a half ago that is doing great. He is constantly picking at the glass and keeps my powerheads really clean. He also likes to perch on his nori clip on the front glass. I was getting worried a few weeks ago because it appeared he was getting skinnier, but last week he discovered how to eat flake food. I experimented with pellets, frozen, nori, but he really likes the flake. Now when i feed he hovers at the top and "pecks" at the water surface to score some flakes. Now he's fat again.
