The Ramshorns snails in my tank are kinda doing poorly (meanwhile, the ones from Mum's place, that originally came from my tank, and are the same age, are doing very well).
It's some sort of Calcium deficiency.
Yesterday (and earlier today), I tried in vain to feed them Spinach leaves (damn things wouldn't sink!). Scratch that then.....
Now I'm going for egg shells (snails can graze on them for Calcium, and it won't disrupt the fish I have in there). Hopefully these will sink....
Future plans include buying pellets designed for Shrimps and other crustaceans (would have bought some today if the pet store wasn't closed). As well as a DIY Snail Jello recipe (I've found 2 different recipes).
Many people consider Ramshorns as pests. But I think they are cool pets (apparently they come in various colors)
And here's some baby ones....
