I have an 8 in common pleco from my lfs who i have had for 2 years. The first year I am sad to say I starved and thought they were only there to clean the glass. Then I found this site through youtube and realized I am suppose to feed them. I feel really bad about that year and am glad I just happened to put drift wood in there for him to eat, but I did not know any better. He currently eats either 1/4 cucumber, zucchini, or yellow squash, or 1/2 a mushroom daily. After cleaning his tank the other day I noticed just how much he poos. There is at least 3 feet being produced daily, and a large amount is white. At first I thought this was because he mostly eats white foods and when I feed him zucchini and he starts to eat the peels it is bright green. Also there are 4 bluegill, and none of them poop white. Am I overfeeding which I have is hard to do? Could there be a parasite, and if so how do I treat it.
