Hi! I went out and bought shrimp pellets and algae wafers for my clown loaches. Is it just my fish because all of my fish pick at them for hours and hours and they seem impossible to eat. I keep reading all these good things about them but they are hard as rocks. Is it supposed to take them all day to eat these. They only thing I can get my clown loaches to eat are the freezedried tubifex worms that I use a holder to keep down near the bottom. Other than that because they won't come to the surface to eat I don't know what to feed them. Would it be ok to feed the worms every other day or so. Please help they are hungry and trying to eat but seem to be getting nowhere. Thanks Leah
