I have some ramshorns in my tank but recently all the large ones seem to be dying off. There are still a fair few smaller ones but a couple of months ago I noticed the empty shell of a couple of the larger ones and since then it seems that once they get to about 1cm they die off.
I don't think anything would have predated them (tank only had sterbai Cory, black neon tetras Otis, shrimps and snails) but did think that the MTS might be outcompeting them for food but I rarely see empty shells of smaller snails and I would have thought this would affect the whole population (not to mention that the ramshorns tend to graze in places the MTS don't normally get to)
It isn't old age as they were only added nine months ago and they were young ones?
The alive one here is about 8mm and looks fine but you can see one of the empty shells next to it.
Any ideas?
