Interesting question, I have 3 in a community tank, that are fine with each other, they had their spats but things worked out with a little jiggleing!I can't say they "like" it because I'm not the fish in this situation, but they do seem to accept it!Some are just not cut out for sorority life, some are too weak, or too strong, the only way you can find out is to try it, it may take a while for them to establish a pecking order, but bare with them, they will get there! Also make sure they're all females, I got 2 females and a male and only found out 2 months in, pineapple has his own tank now! :)
Proud mum of : Gandalf, Lily,(ohm bettas)
Pineapple (male betta)
Jade, Indigo (hm bettas)
a few platys, a few guppies,
a few shrimp,
and whatever else sneaked into my tank while I wasnt looking
If it moves. . .BITE IT!!!
