Stocking 25 gal planted tank

[rg0p]

Hi,

Our 25 gallon tank was bought as a kit (Aqueon premium kit). The tank set-up is:
Aqueon 30 HOB (came with the kit) and fluval 206 canister (added later)
150 watt Aqueon heater
T5 NO 6700K daylight and T5 Colormax (Both 14 watt & 24 inch)

Plants(currently): amazon sword (2), jungle vals, anacharis, anubias nana, java fern (1), windelov fern (2), mayaca
Planning to add: wisteria, telenthera cardinalis (my daughter wants this!) & dwarf hairgrass

Fish (currently): rasboras (7), cardinal tetra (3), neon tetra (2)
Planning to add: some more cardinal tetras (may be 4-5), male betta, gold rams (pair), some kind of corys (3-4), african dwarf frog, may be an algae eater like oto (1?; if needed)

What do you think? Any other suggestions, modifications, advice very much appreciated.
I'm a bit concerned about adding the male betta, but there are conflicting opinions. One my kids is really interested in getting a betta. I am not sure I want to have separate tank. I do have a 2.5 gal which I use as hospital tank.
What kind of corys are good for a 25 gal tank?
Will gold rams be OK with a male betta in the tank? Or with any of other choices?
I hear ADF being a slow one may be a problem while feeding??

Thanks a bunch in advance.
