So i got a scooter blenny a few months ago and he was doing great swimming around all day and night. I made sure i had plenty before i got him by stocking my fuge with pods. and i waited about 3 months. I regularly check glass for them and there all over both tank and fuge. Around yesterday he stopped moving much and hes in the same place as he was this morning, all other fish are great and all params are good... any thoughts? Also hes about 3-4 inches.
