On Sunday I purchased a conch about 1" long and 2 snails. The conch was picked on early but after 2 days he suddenly disappeared and I don't know where. In my tank (55 gal
.) there are places to hide behind rocks and under rocks, but I still don't want my tiny puffer to get the best of him. I also have a snail that has been continually knocked off the rocks by the puffer and is on his back. I try and put him on a rock and he never suctions to it. I think he is still alive because whenever I go to pick him up he hides a bit more but I don't want him to rot in my tank. Will invertabrates just not work in my tank or is there no reason to worry because I have 4 other snails that are doing just fine.Anything would help. Thanks!
