I have a couple of fish left over from my 100 gallon. Cardnal Bang, and bicolors. They are harmless.
I had some cleanup crew left over from the old tank.... I have been going out and buying hermits and snails from all about fish in pleasant hill. I also ordered the 9 for $99 from ipsf.com a month ago, that included workms, clams, hermit, small snails, and macro algae.
I currently have
10 large Turbo snails
