I just got a small lawnmower blenny to try and rid my 72 bowfront of nuisance hair algae. He is in a 20 gallon tank connected to the return mainfold, so no truly a quarantine. I can isolate this tank however if needed. The system reactors, GFO and carbon operate from and to this tank. Question is. How do I feed this guy to make him happy in quarantine and fatten him up while I make sure he has no pests?
