Unlike Turbo snails that prefers cooler water, the Trochus snails is great in reef environments. They scavenge nuisance algae extremely well, well leaving corals along.
Perfect for frag tanks since their small size will not move the frags. Just be mindful of powerhead intakes.
Snails are a valuable part of a well-rounded "cleanup crew", providing valuable scavenging services, feeding off of algae, detritus, and uneaten food. Many of them reproduce regularly in the aquarium, with their larvae providing a supplemental food source for other life forms.
1/4" to 1/2" each. You will receive 5 snails for each pack purchased.
