Multies are great, really entertaining, but when it comes to sheer 'looks' they don't count for much. Very good parents as well, it doesn't take much at all to go from just a few adults to a thriving growing colony of these. Simplistic beauty. Love 'em.
There are many different species, some big and some small, each with there own needs and personalities, so It's pretty safe to say that there is a shellie for everyone
BTW- if you need some shells I've got plenty that would be good for these guys.
