I forgot to add that Arakkis commented these are also shortlived compared to the other nerites we get. I talked to Arakkis about these snails last April and he said they seem to have a shorter lifespan but I haven't determined yet how long they exactly live because I lost my only two Septaria sp.
MsJ, you have everything! I'm so jealous, lol. I can usually only find 1 or 2 limpets in my tank at any point in time and I like them, so when I saw this snail, i got pretty excited.
Septaria are much more finiky than the batman snail.. I have a ton of batmans and *had* a bunch of septaria but now a few months down the road, they didn't survive the tranship.. I'll work on trying again in the near future
