Hello! I saw ur question about breeders in AL.... I do live in Bama, but am just getting started as a breeder I'm in the process of building my sorority (Vada's my only girl atm) and have 3 pretty males (Jade, Hawk & Merlin... Each has his own album)
Hello! Sorry I just saw your post. I currently keep a group of 5 white clouds in my 20 gallon, they share it with a female betta. They have always completely ignored each other. I know lots of people say that white clouds require much cooler temps, but I feel fish are pretty good at adapting.
If you keep just the white clouds and a betta in the 10 gallon, that would probably be ok, just don't add anything else. And if you can ever upgrade that would be good too, as white clouds are very active fish. I think their level of activity would be better with a female betta, since females are much faster, she probably wouldn't be bothered by them.
