An interesting freshwater snail to keep is the Rabbit Snail. Also called an Elephant Snail, a Rabbit Snail can be a great addition to an established community tank. Rabbit Snails are very peaceful creatures. They are not aggressive by any means, and they seem very curious about their surroundings. Rabbit Snails are active during the day and can be very active at night.
When buying Rabbit Snails, look for snails that appear to be moving across hard surfaces or stuck to the glass. If a Rabbit Snail is motionless on the tank bottom, laying upside down or floating, the snail may be dead or dying. Also, look for snails that have thick looking shells free from cracks, deep pits or evidence of excessive wear. Thin, cracked or worn out shells can be indications the snail is unhealthy or have been in water that was acidic or low Calcium. Also, keep in mind that Rabbit Snails may be kept in display tanks with roughens that may take nips at their tentacles, so be sure the snail looks complete before buying.
