thanks guys! the snail (cerulean) is just kinda there to keep todo company. he isnt aggressive with him at all, just interested when shes on the move. though i have noticed that im doing more water changes with the snail in there... she leaves a bit of slime every where. but she is REALLY interesting to watch. the first time she reached out with her siphon and breathed from the top of the water, i didnt know what was going on!!
