Bettas & other fish

[Shoebox_16]

I have a male Betta currently in a 3g, heated and filtered. But I really want him to have some friends, and I've heard they can be housed with tetras. I know I would have to get a bigger tank, oc.

My questions are (lol):

- What fish can Bettas be kept with?
- And what size would I need? Like, for example, a Betta and 6 tetras?

Hara hara
Glass catfish

Cichlids
This seems a hit or miss. The following listed are possible but don't keep your hopes up they will thrive together. Do not mix if cichlids are in spawning mode.

Discus
Blue rams
Bolivian rams
Apistogrammas

Livebearers
Guppies
Platies
Mollies (not all will work)

Get a 10g for tetras and betta altogether.

 

[jm1212]

at least a ten gallon to keep him with smaller tetras like neons or cardinals.

a 20 for larger tetras or rasboras.

Stocking 3 (for a 6 gallon)
1 male OR female betta
2 African Dwarf Frogs

That's from a discussion thread on here ^

Why can I put my male Betta in with two ADF's in a six gallon, and yet not 6 tetras? What about 4 tetras?

ADF's don't need quite as much space as a school of tetras, and 4 tetras isn't really enough for a school (schooling fish do better in larger groups).

Lupin has given a good first list of compatible fish. There are also lots of less common fish that would work. Bettas are basically OK if they can't swim as fast as the fish they are with and the fish they are with won't nip their fins. They ignore most bottom dwellers so those are also OK.
