Bred in my classroom 10-gallon aquarium! These tiny shell dwellers commonly known as "multis" have been such a fun addition and the kids LOVE watching them constantly redecorate their tank. They are small fish with huge personalities — digging in the sand, moving shells, and creating their own little neighborhoods all day long.

I keep mine on a substrate of aragonite sand with plenty of escargot shells that can be found inexpensively on Amazon.
