So at my part time job we have what looks like a 55 gallon high tank and in it are 4 varying types of tetras, one 8 inch pleco and 1 2 inch Candy Striped pleco. Unfortunately no one really cares for the tank and I find myself having to do water changes on my free time. (Apparently they did them only once every 4-5 weeks.) The pleco seems to have stopped growing due to the cramped space and has also begun to get skinnier if thats even a thing. Compared to my pleco which is only about 5-6 inches, this pleco is half his girth. Does anyone know of some kind of food I could buy that could possibly help it get a little better.
