FAQ
Frequently Asked Questions
Not inherently harmful; they consume algae and detritus, but overpopulation can indicate overfeeding or imbalance.
They are hermaphroditic and lay gelatinous egg clusters on hard surfaces, often leading to rapid population growth.
Briefly, but they are primarily aquatic; extended periods out of water are fatal.
Ramshorns have flat, disk-like shells that coil in one plane; bladder snails have elongated, conical shells that spiral to one side.
