My five gallon finished cycling earlier this week, so to celebrate I went out and bought three TINY pygmy cories. I found them on the web and saw them in the nano tank at the LFS. So far I think that they are fantastic little fish. I really cannot believe how tiny they are. I was worried about them overstocking the tank once my new halfmoon betta gets put in, but I'm really not concerned anymore. anybody else keep these?
