Currently I only have Charlie, my halfmoon, in a ten gallon, and I was wondering what other fish can go with him(: I was thinking a school of 5 neon tetras, but that's all I can think of. I know the tank is pretty bare, but I'm going to heavily plant it in about a week and add more hiding spots. Anything will help, thanks!
You can have a small school(4) of cories, either Albino or Panda species, but Albino is more hardy. But keep in mind cories need either sand or really small , smooth gravel so as not the hurt their sensitive Mouths. They are sensitive to light and need hiding places, too. Oh, and I can't see a filter in the tank so if you add any species of new fish you need one
Hahah that's the best thing about this tank, you can't see the filter:D Its in the right corner, its a hang-on-back. And when you say that albino cories are sensitive to light, do they have to have the light off? Or do they need a lot of hiding spots with shade?
The filters behind the green plant, it's a HOB from what I can see (hangs on back).
I would say you're pretty open to a school of small tetras. Don't go with Danios, no matter what people tell you at a pet store. They will nip the Bettas fins. Personally I would go with a bottom dweller like Cory's so you have more fish to care and admire but the Betta gets the whole top level to himself :)
