I keep my betta with two fantail guppies (I don't recommend this, but my betta seems particularily sweet so I thought I would try, and he ignores them completely :clap: ) and three khuli loaches in my ten gallon tank. Do you have a red betta? People seem to think those are the most aggressive, and I have a blue one and he's pretty sweet. . .don't recommend mollies either though, mine killed one of those. :rant: Basically I would try:
~platies (mine didn't like them but he never tried to hurt them; just flared when they got too close)
~harlequin rasboras (totally peaceful)
~khuli loaches
~corydoras catfish
~guppies (depending on his mood and their finnage)
~neon tetra (I am planning on trying it, can let you know of my progress if you want :idea: shouldn't be a problem)
~hatchet fish (never tried it. . .shouldn't be a prob tho)
~mollies-WITH SOME BETTAS
~cherry barbs (sweet never bothered mine)
~you COULD try gouramis, some people can pull it off with sweet gouramis and sweet bettas, but unless you have a 20 gallon or larger, I wouldn't try it in case one needs to hide
I hope that helps
