The pond is only about 70' X 110'. I hope they are just bedding or something like that. They used to come eat like piranahs. I did stop feeding them as we had a pretty cold winter but usually there was some little ones eating the food, didn't even see them. Would usually see the bream hitting the top of the water for bugs in the evening and early morning and haven't seen that either. I may have had a bream over population, that is cured for sure.
