if you're in the the Pittsburgh area check out All Oddball Aquatics. He specializes in cories, cichlids and dwarf cichlids but has expanded the "brick and mortar" store so it's open 7 days a week and also stocks the "usual" fish as well - neons, rainbows, rasboras, etc. and some equipment stock.
More importantly, he's started up a planted section as well, even has some E. stellata from time to time
I've gotten some riccia from him as well although I don't know if this is a usual stock.
Eric is the owner operator, and Tim is his buddy that is into planted tanks. Both are great guys and helpful.
He's located a few minutes South east of the South Side, so you can pick up a Primanti's and a beer on the way then drop by!
By far my favorite place in the Pittsburgh/ East of Pittsburgh area to "window shop".
