Frequently asked questions
Do Japanese trapdoor snails need a heater?
No — this is the snail for unheated setups. They are comfortable from the low 50s through the high 70s and routinely overwinter in outdoor ponds under ice. In a tropical tank above 80°F their metabolism runs hot and lifespan shortens noticeably.
Will trapdoor snails reproduce out of control?
No. They are slow livebearers — a female releases small numbers of fully formed young a few times a year, and you need both sexes. Pond keepers usually buy them by the dozen precisely because the population grows so slowly.
