i have two apple snails. one goes in his shell and closes the door when ever i touch it, the other one just lets me pick him up! he just hangs out. i even put blood worms up to him, and he will just slurp them up... while hanging in mid air by his shell! he is pshcho. he even comes to the glass when i feed my goldies, because he knows i will give him blood worms. no lie. whereever he is in the tank he just comes to the glass. i put a blood worm by him and he comes over and slurps it up while stuck to the glass so i can see it all. does any one have any other snails like this?
