Mystery Snail tank mates
A peaceful glass-walker that ignores live plants. Bigger and messier than nerites, with a real bioload and a calcium dependency. Confirm the species at the shop to avoid the banned channelled apple snail.
Common mistakeBuying channelled apple snails sold as mystery snails is how keepers invent missing stem plants within a week. True mystery snails (Pomacea bridgesii) are gentler on plants; mislabelled channels are not. Confirm species, feed wafers, and watch for egg clutches above the waterline.
