What are my options for stocking a 7 gallon?

Bettas almost always need to be seperated. Unless they are the peaceful kind, or have been together as fry there is little chance of them getting along. Maybe try a few cories or and ADF?

I dunno why everyone smart here keeps recommending cories for little tanks. i thought most corys get to be nearly 3" long. also hefty little buggers. wouldnt they be kinda crowded?
ANYway, you could MAYBE, if you are lucky have two female bettas get along. but i can't imagine two males cohabiting peacefully in a 7 gallon. not even the 'peaceful beta' from what i have heard of them.
I'd check out profiles of gouramis to see if any could work. maybe a honey gourami? I don't know.
I know they seem smallish, but how about a couple or three or four male guppies?
They might be even more enjoyable than a betta.
If you get one betta you could also get a couple of dwarf african frogs and or a snail.
i can't think of biggish fish that you could fit more than oneof in there.

Actually Zazz, there are 3 types of dwarf cory cats that stay under 1.5 inches, are not big bodied and are totally entertaining: c. habrosus, c. pygmaeus, c. hastatus would all probably be okay in a 7 gallon with a male betta. Plants and any other type of hiding places such as wood would be a good idea, though. Good luck

Thanks! Dwarf cory, cool. I have heard the c. pygmaeus Don't stay as strictly to the bottom as the full sized cory. Do you know if thats true of each of these?
I know I know, :OT: sort of, but maybe needcash wants to know too *S

I have 10 c. pygmaeus in my 10g planted. They are very interesting. It is true that they move throughout the water column but do prefer the bottom. Often I find them under the driftwood. Sometimes they hover like little helicopters.

There are many types of dwarf species. I almost stocked my 10 with some checker board cichlids (sp?). They are small and nice looking peaceful cichlids!

I have c. pygmaeus in my 20g. They sometimes school and sometimes come apart. But I always see them. As soon as I walk into the room the swim up the the glass faster than any other fish.

Yes, the dwarf cory cats tend to be bottom and middle of the tank, not just the bottom. Some even rest on plant leaves, etc. My c. habrosus tend to stick together a lot in my 10 gallon, they are so fun to watch!
