Hello fishlore! Well, I've decided my 10 gallon is a bit too boring for me. It used to have 1 betta and 6 pygmy cories in it; the cories always hid, and the betta has more of a shy personality, though I did see him every now and again. Anyway, I moved the pygmies to my 20 gallon, and purchased 3 guppies (1 male, 2 females) for the 10 gallon. The betta's been a good boy, so I'm thinking I might want to add a few more guppies- definitely a couple more females. I've been getting mixed reviews online about how many guppies can comfortably fit into a 10 gallon- and that's where you guys come in! Thanks in advance!
