If we ever get any rain around here, and I get some water in my newly dug grow out pond, I was thinking about throwing in a few RES bought from the itinerate fish truck when he stops at the local farm store next month. Will they find anything to eat in a new pond? There's no snails or minnows or anything else in it right now. Will they survive on Aquamax and any microscopic organisms that might be growing in the water?
