barbs, angels, gouramis, and some kinds of tetras are all bad tankmates as they are more likely to nip at the betta. i had three neons tear up a male betta literally overnight.
Yup, I agree. You're asking for trouble trying to mix bettas with what you mentioned or guppies, platies, most livebearers for that matter, but especially the first 2.
Those of you that are wanting to put a betta in your community tank, think carefully about what your stock is and whether they will be compatable. Bettas are extremely prone to be nipped, and not only that, when your betta is asleep, if something tries to chew on him he will likely not wake up. They're some deep sleepers.
As far as mixing several male bettas together, I do NOT recommend this. If you're having to ask "Is there any way I can mix male bettas together?" You shouldn't be doing it. There are a few people that have had luck mixing certain males together, but this is partially luck and partially picking the right male betta. Some male bettas are almost completely nonaggressive and will retreat at the sight of another male or lose interest after a few seconds. I don't recommend simply planting your tank heavily and throwing a bunch of male bettas in there, this is NOT foolproof. As soon as one male sees another they will most likely fight and one will end up dead. This will go on until either a couple of males establish territory and everyone else is gone, or you'll end up with one male left. At the least you'll likely have a bunch of bettas with ripped fins and potential for disease.
If you want to mix bettas together that bad try females. And I'll warn everyone right now that even some females won't tolerate other females so be careful. And don't mix the lighter colored whiteish or white and orange bettas with the darker colored purple, red, blue, etc, because they lighter colored ones always seem to get picked on really bad. Don't know why, the other females just seem hostile towards them. I had this experience with my own, and after talking to several people it's apparently pretty common.
