I added 7 "feeder" goldfish to my tank to help it cycle and yes, they move very fast, scrounging for food where my 2 apple snails cruise around...but after several hours after adding these hyper fish...I noticed my big snail is floating at surface, body half hanging out...one goldfish in particular picking at him....he stopped after awhile...I tried to sink my snail but he keeps floating and the strange part is he floats in the bumpy waterfall of the filter current...which is logical since the current is like a magnet to anything floating...I can't imagine this wouldn't be stressful for the snail...bouncing around like that...I even noticed for awhile his antennaes floating too until goldfish picked at him...then he sucked more of himself back in....Is this something to be worried about...my littlest snail is still cruising around...just the big one is floating. Is he okay?
I'm also wondering how to feed the snails since the goldfish are pigs!
I want everyone to co-exist happily...can they?
