.... No.
Separate them. Now. Fighting is NOT the only issue here, as many people mentioned in your other post on this issue.
- Goldfish are coldwater fish, not tropical fish. Bettas need a temp of 74-82 to survive. Goldfish will be too warm and produce way too much waste in this temp. They will also have breathing troubles.
- Goldfish and bettas have entirely different dietary needs. And goldfish will def. out-compete your bettas for food.
- Goldfish like a strong current. Bettas will physically stress and die from a strong current.
- Goldfish WILL rip of the bettas fins when they get big enough; they're attracted to long, flowy, potentially meal-like things.
- Goldfish need at least 20gal per fish to survive their full life expectancy. Bettas become stressed in tanks greater than 10 gal. Your goldfish are only in a 10 gal as it is, which isn't enough for
one goldfish.
- Goldfish are social fish. Bettas are not social fish, and are unsettled by other fish in the tank.
- Goldfish are huge waste producters. Bettas are sensitive to filthy water.
I'm a little annoyed right now. We told you in the thread when you asked if they could go together that it was an absolute "no." You've done it anyways. And since you are a begginner and clearly do not know basic betta or goldfish care, you should not try saltwater; it is a very difficult, involved type of tank set-up, and the fish will very inevitably die. Please reconsider, and move your betta back into another tank.
