I'm not exactly sure. I know that I would like 2 Kuhli Loaches, a Dwarf Gourami or 2, 2 ghost shrimp, a couple Turquoise Danios, maybe a couple Golden Harlequin Rasboras, maybe some neons, and maybe a couple cory's. I'm doubting i can put all those in one 10 gal tank, but they're what I'm currently looking at.
