I’ve had my lawnmower Blenny for 5 months or so. He was healthy and growing one day and I check the tank and the hermits are piled on him like a wild feast! The only thing I could point to is not enough micro-algae on rocks and glass to sustain him? He didn’t take frozen foods or pellets ever. A very frustrating loss... Any pointers from you guys on keeping these guys happy and healthy?
