I just set up a 20gal. Makes 8 total but their all little. LOL Talk w/ a woman that owns a pet store and she seems interested in guppies. I have no shortage of them. My last tank I did red shrimp. and a good supply of cleaners. nerite snails, snowball pleco and red nosed pleco the snails themselves and a couple cory cats. Only 6 "fish". 3 rasbora hexs and 3 white cloud minnows in a 40 tall. Live plants and driftwood to round every thing out and a huge coating of hair algae I cant seem to beat.
