Starving skinny lawnmower blenny

[tucker]

I got a lawnmower blenny about a month ago and he was fat. Now he is super skinny and I’m worried since he doesn’t have much to graze on in my 20 gallon. I tried nori but he doesn’t seem interested may be that my fish and shrimp scare him away as they also go after it. Any ideas on foods or how to feed?

Unfortunately this blen, does not usually last more than 6-8 months in a home aquarium.

Algae on a clip is all that worked for me, but mount it closer to the bottom or attach to a small rock with elastic band.
