Well I think that I've had some of my clean up crew die off and I'm in need of some additions. Right now I have some blue legged hermits, nass. snails? (they bury themselves and have a long trunk thing), and a few bumblebee snails. I think i'm going to add some more hermits, and was wondering what snails should I add? Keep in mind I have a 30g w/ some leathers, a bubble coral, zoo's, and some xenia. So any ideas? Oh yea, my tank has been running for almost a year.
