threadfin rainbowfish plus betta

[freshwaterfishies]

so i have a betta fish already but i was wondering if i could introduce a threadfin rainbowfish to the tank or would the betta go after him or her or the other way around.
PS if this is in the worn spot my apologies still learning were things go.

A few factors is it colorful tank size and decorations.

I wouldn't. I have these fish, they are very small and delicate, I don't think they'd put up with a betta.
