Oh, that’s a new one to me though must admit it’s been a while since had snails in my tanks as have not got a up and running tank at the moment and not up to date with what’s around these day.
Reckon I got some catching up to do, will have a look for Black Devil snails on google methinks
Looking at the shell and pics I saw online, it looks lime rabbit snails have shells that are more rigid. These ones have smooth shells more like black devils. Hmm.
