I have a a twenty gallon (20 gal) split tank. One side has a single male Betta (1 male Betta) and the other side has three female Bettas (3 female Bettas).
I was wondering if I could get
-Another female Betta (1 female Betta)
-One or two cory's (1-2 cory's)
-A African dwarf frog (1 ADF)
-A Apple Snail (one apple snail)
-Some live plants (don't know if that would add to the bio-load or not)
The frog would be with my females along with one Cory (1 frog 1 cory)
The snail would be with the male along with the other Cory if I could get two.
Would I be over loading the tank to much? If I am which would you recommend I get and what should I forget about?
Note: I might be removing one female Betta because she is being very aggressive.
