No. Ideally in this situation you would need a heavily filtered 400 gallon minimum. To properly fit the group as all of the fish that you have aqueried have a very high bio load, and a very large potential maximum size. Leasing them best suiting more so of a pond for that number than any home aquarium
There are also many potential problems to think about when consodering compatibility issues,
common goldfish prefer cold temperatures, making them cold water fish, while bettas prefer warmer temperatures of around 78. Which makes them tropical fish
Goldfish, and bettas have very widely different diets such as goldfish being mainly omnivorous. But mainly prefer planted base foods, in my experience, while bettas a mainly carnivorous. They ideally should be fed in different tanks away from eachother
Common goldfish get to a maximum size of around 16 inches, while bettas stay at a measly 3 inches. The goldfish's re very likely to cause problems, and eat the bettas
Goldfish have relatively long fins and bettas are known to nip at them along with attacking the goldfish itself
