I added a few Black Margarita Snails to my 20-gallon reef tank and they’ve been cleaning the glass and rock surfaces efficiently. They’re quiet, don’t stress the fish, and look great with the decor. Easy to spot and maintain.

These snails have been active since I introduced them. They seem to prefer areas with more algae and keep the tank looking tidy. A small but effective addition to my aquarium.
