thanks again Jeff, great job on the GB.very impressed at your plumbing skills:wow: .i put them in the tank last night, and the hermits went right after the snails.i moved the snails to one side of the tank away from the hermits.today seems like alot of the astreas are not really moving.i flipped a bunch of them over beause they were upside down and there are a couple on the glass.whats going on with the rest of the groups critters?
