I have a lawnmower blenny that's been in my tank for a couple of weeks now, after a couple of weeks in the QT. It seems to be acting fine, but is getting skinny. Is there something I can feed him since he doesn't seem to be getting enough to eat from the tank? I've tried some algae wafers and a little piece of dried seaweed to try and help, but he doesn't seem interested. I seem him occasionally nip at the surface to eat, but it is making me nervous that he isn't getting fatter. My tank size is over 200 gallons, so that shouldn't be the issue, and there is some algae, but not a huge amount. The tank has been running (after cycle) for about 3 months now and all other inhabitants seem to be doing well.
