betta compatible

It depends on what you have in your community tank, some fish get along with bettas and vice versa and others don't.

Most tetras, cories, many loaches, and inverts will be fine with a betta. I've kept mine in with kuhli loaches, bristlenose, cories, neons, upside down cats, a spiny eel, blue tetras, and others happily. Amano shrimp and snails are good companions as well.

Avoid other labyrinth fish (ie, gouamies, paradise fish, other bettas) and known nippy fish, like barbs. Guppies are hit or miss--sometimes it works, sometimes it doesn't.

There is a number of things that will go fine with him, of course khuli loaches and cories. I know other people will disagree with me, but Tetra species. Maybe a pair of Dwarf cichlids. Female guppies, bettas generally will go after the males because of their finnage and coloration. In my experience Dwarf Gourami and bettas leave each other alone. I'd also reccomend just doing some research on the subject, find out what other people have discovered. I'm a rather limited source for this subject as my sister and I have had several male betta's living together, along with several female bettas and we had absolutely no issues with it beyond the occasional flaring at one another. I however stress I do not reccomend you try doing that, I think we just ended up getting lucky, and this was also in a 75 gallon tank where if need be they could find a place to hide, which really didn't happen, most of the time the bettas just hung out together. lol again in a 16gallon, DO NOT try to keep two male bettas together or female bettas with him.

Well, i just got a wonderful little companion for my betta in his 3 gallon tank. A little african dwarf frog!

It might be a little lonely having just the two of them in a 16 gallon, though.

There's a general rule of thumb with bettas and other fish- no other fish that are nippy and might bite at the betta's lovely fins, and no other fish that has long fins that the betta will get mad at (instinct to eliminate the competitor ).

I will agree with what others have suggested. Because there are so many fish out there it is hard to list all the possible combinations, but what has been suggested is a good starting point.

I have been successful with cories and white cloud minnows. But with white clouds you should keep the temp down to the low 70's, which will be fine for the cories and bettas. White clouds are cool water fish so this is a fine compromise temperature.
