I have a small Common Pleco, (About an inch) that wont eat the wafers I have. The brand is "Hitari Tropical Algae Wafers". The Pleco is currently in the tank alone. The tank is a 40 gallon breeder with a bit of hiding spots. Water parameters are good: 0Ammonia 0Nitrite 10Nitrate. There is a lot of brown algae and green string algae in the tank because I cycled it for around 2 months using pure ammonia. He seems fine but he just wont eat the wafers. I also have Seachem chlorella flakes but those will go everywhere in the tank and dirty it up quick if he doesn't eat it. I just want to make sure he's eating enough. How could I get him to eat?
