goldfish with betta

is it ok to keep my goldfish with a betta? temp is about 27 C. tank holds about 8 gallons. there are two pots and one plant inside the tank

no no no no no way!

your tank is too small for the goldfish alone, you dont want any more fish in there.

Bettas should be kept alone, or with well researched tank mates that need the same requirements.
Goldfish are coolwater fish, bettas need the warmer end of tropical temps. goldfish need string filtration which will create a lot of current, bettas hate current.
So no, please dont do it.
