I have a question on how often I should keep out cucumber in my feed clips for them Plecos. My tank is spotless and I do drop some sinking pellets for them. I just dont want to do them harm by giving them too much cucumber to eat at will. Is this a problem? There are two of them in a 75 set up with some Cory cats. The Plecos are eating a slice each a day. Everyone looks happy , water is in great shape, just worried about giving them too much of a good thing and what else would you feed these guys to mix it up for them
