If you have ever kept a freshwater aquarium, there is a good chance you have encountered the bladder snail — often without even inviting it in. It arrives quietly, tucked inside a live plant or hiding in a water sample. Before you know it, you have dozens of them. I find the bladder snail fascinating,…
Pond snails belong to one of the most successful groups of freshwater invertebrates on the planet. They have survived for millions of years, and adapted to an enormous range of environments.

Baby ramshorn snails are among the most frequently encountered creatures in the freshwater aquariums. They arrive unannounced, often hitchhiking as eggs on plant leaves or tucked invisibly into shipping water. Within weeks, what seemed like nothing became a population. For some aquarists, this is an unwelcome surprise. For others — particularly those who keep pufferfish,…
The reproductive biology of ramshorn snails is one of the primary reasons they are so widespread — and so frequently labeled a pest. A single egg clutch can contain up to 40 embryos. With multiple clutches laid per week and an incubation period as short as ten days in warm water, the population can quickly…

If you have ever come across a snail with a long, twisting shell and a face that genuinely resembles a rabbit — complete with floppy antennae and a wrinkled snout — then you have already met the Tylomelania, more popularly known as the rabbit snail. I remember the first time I saw one slowly making…
At some point, almost every betta keeper stares at the algae creeping up the glass and thinks: I need help in here. Betta fish are stunning and rewarding to keep, but they are also notoriously territorial. Adding any tankmate to a betta aquarium carries a degree of uncertainty. Get it wrong, and the result is…
If you are new to keeping nerite snails, there is a good chance you have already spotted them — small, white, sesame-seed-like dots scattered across your aquarium glass, stuck firm on driftwood, or clustered along plant stems. The first time I noticed them in my own tank, I genuinely did not know what I was…
