Hey Selena,congrats on your snail.He's a real pretty yellow/gold.
I too have kept snails for years,and to be honest,I try like heck not to add them to the Goldie tanks if I can help it. The goldfish will check them out occasionally,but usually if they're bigger than their mouth,most times they will eventually leave them alone.

My biggest problem in goldy tanks was the fact that its very hard to keep them well fed with piggy goldfish around,and the fact that I have super strong filters was another problem for the smaller snails,no matter what I tried.If you dont mind isolating to feed,then I'm sure that he'll do okay in there with his fishy buddies.
After I lost Chewy,I just started keeping only the Spixies,which don't get near as big as the other types I kept.
They are actually in goldy tanks right now,and doing pretty well,as the fish are all pretty small.Good luck and keep us updated.
