Old thread I know, but figured I would chime in here. I have an assortment of a few hundred dwarf ceriths and dwarf planaxis in my tank and over the past few weeks, I've witnessed my scoly eating TONS of them! Scoly was not doing that prior and nothing in my tank has changed. I will try feeding it more often to see if that helps at all. The scoly looks inflated and happy, so I don't necessarily mind except that there is a graveyard of shells beginning to collect in front of it lol.
