The optimal water temperature for apple snails lays between 18 to 28°C (65-82°F). As with many cold-blooded animals, apple snails are more active at higher temperatures. At higher temperatures, they eat faster, creep faster and they grow faster. Also higher temperatures mainly induce the reproduction of the apple snail. At lower temperatures (18°C/65°F) the apple snail enters a dormancy state in which they creep away in the mud and become very inactive. Temperatures below 18°C/65°F should be avoided as the mortality rate quickly increases.
