Do you guys think that getting a group of dwarf cories and a betta is pushing a ten gal? Other people said it would be fine...

I think that dwarf Corys are much better than regular ones. However, People say that they aren't much of a bottom dweller - FYI. There are 3 species of "dwarf" Cory though - not sure if that's true of all of them or not.

If Corydoras hastatus or Corydoras habrosus are the intended cory, as mentioned previously, then in a 10g you want no fewer than 9 of them. These two species need larger groups, and a nicely planted 10g will be fine for 9-12.

Both also will be healthier over sand. I've had them over both fine gravel (much finer than that in the photo here) and over sand, and they lived longer with sand. A professional catfish importer/breeder clued me in to the sand.

C. hastatus is rarely on the substrate; this species loves to shoal mid-water. While it might be fine with a Betta, it is risky. Betta are not community fish, and individual Betta clearly have differing temperaments, but I tend to follow the majority to be safe.

C. habrosus is more s substrate cory, though it likes to move ujp to browse any surface like plant leaves, wood, etc.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
