Lawnmower Blenny

[naesco]

Try spirulina discs. They fall to the bottom and he may eat them later.
Leave one end of your glass unclean so that he can suck the algae off the glass.
Throw some smooth stones (the blue ones about 1.5 inches) in a highly lit area of the tank.

He should be plump. If he is thin he is starving so you need to add algae (nori is great) to the tank.

Soak the nori in garlic extreme as the garlic has been know to get a fish that is fussy about eating, eating again.
Good Luck
