ram in a 20 gal

Shouldn't be a problem, but all fish are different
Try and see
Natural Rams for $4, wow
now that's a deal!
Go for it!
 
The betta and ram may or may not work out, but IMO your bigger issue will be with the betta and guppies. This combination rarely works out for any length of time.
 
I have one with a Betta, the Betta is a bit of a jerk as far as Betta go. Once in a while the Betta will chase the Ram, but I've never seen the ram chase the Betta, I've also never seen the Betta actually catch the ram. It's like chasing a Ferrari in a garbage truck.

Your mileage may vary, have a back up plan if you decide to try it.
 
I'd add more kuhlis & corys first then think about if a ram would work. Depends on the betta & ram. Either sex would work as well, pink belly vs dorsal extensions, both are pretty

the betta and guppies are fine,he actually gets kinda lonely if he cannot find them the only time he will chase them is when they stick thier lil guppy butts in his face,and he only chases them a feww inches even then

i think ill go for it
 
IME the temperament of a betta is always subject to change. Hopefully it continues to work out. ;)
