Dwarf Cerith Snail 10 Pack
The Dwarf Cerith Snail (Cerithiidae sp.) is a small but effective algae eater, measuring approximately half an inch in size. These snails are ideal for small aquariums where other cleaners cannot reach. They consume various types of algae, cyanobacteria, detritus, and diatoms, helping maintain a clean environment.
For optimal performance, it is recommended to have at least four snails per gallon of water. Dwarf Ceriths are nocturnal and highly hardy, though they are sensitive to rapid changes in salinity and pH during acclimation.
A tank lid is strongly advised as these snails can crawl out of the aquarium. Acclimate the snails slowly using a drip method to avoid stress.

I bought 10 Dwarf Cerith Snails for my 10-gallon tank. They’ve been active since day one and are eating algae on the glass and substrate. I keep the tank covered, and they haven’t escaped. They seem to be thriving and are a great addition to my tank.

The snails arrived quickly and are small but effective. I noticed a reduction in green algae after a week. I have a lid on the tank now, which I wish I had before. They’re hardy and don’t seem to stress easily.

I’ve had a few snail species before, but these are the most efficient at cleaning diatoms and detritus. I now have four per gallon and they’re active at night. No issues with acclimation after following the drip method.
