I not only add these to my aquarium but I have them in my refugium also and they do the job at keeping algae at bay in my refugium. Mixed with snails and other cleaners, they do the job.

Got these specifically for my refugium. My tank has been cycled for a while now but occasionally I’ll keep fighting this diatom issue. My refugium was actually looking pretty slimy so I got these snails knowing they eat diatoms. Within 2 weeks, my walls are fairly clean and I can actually see my cheato growing. Don’t hesitate to pick up a few of these especially if you have some algae issues from time to time.

All snails arrived healthy and accounted for.

These are by far my favorite snail for the reef tank. They kinda look like astrea snails, but are prettier with their maroon bands on their shell and black foot. And, the best part? Unlike most of the other choices for reef snails, they can almost always right themselves if they fall off the rock or glass and land on their shells. They’re also better algae eaters than most other snails because they actually eat filamentous algae, and not just film algae like most others.

I think this is one of the best looking cleaner snails available. I've have some now that are over 5 years old and still going strong.
