Tricolor Zebra Thorn Nerite Snail

Remarks: Nerite Snails are excellent algae grazers and they do not reproduce in freshwater due to their larvae requiring brackish conditions, meaning you won't be overrun with tiny snails seemingly crawling out of the substrate. They will deposit eggs on many surfaces, however, and these can be scraped off or left to naturally decay. They seem to appreciate brown algae (diatoms) most. Any tanks housing these snails should have a tight-fitting lid as they can crawl up the glass and escape. Luckily, these snails can close up their shells when out of water to slow the rate at which they dry out. Some have reported finding snails 24 hours or longer after escape that perk back up when placed back in the water.

  The tricolor zebra thorn nerite snail is one of the most unique nerite species in the hobby. This is due to not only their highly variable colors and patterns, but also the fascinating spikes or "horns" present on their shells. These spikes help discourage fish in the wild from trying to eat them and can grow back if they are broken off provided the snail has access to plenty of minerals to feed on. This nerite is notably smaller and less hardy than the more common zebra or tiger nerite snails so care should be taken to ensure water quality is kept pristine. 

  B-grade snails have imperfections on their shells such as small chips, broken thorns, or scratches but none that are a threat to the snail's health. They most likely will eventually heal and look like any other snail.
