Do betta fish go together with goldfish?

Beta fish are solitary fish and generally will attack/annoy any other fish until they are dead. Check with your local pet shop that sell fish to inquire about what, if any, fish can co-exist with Beta. it all depends on how aggressive you betta fish is, i own two male bettas, i placed my first one in the tank with 3 other goldfishes and they get along fine, however when i replaced the 1st betta with the 2nd one, it was the more aggressive one and attacked my other fishes...... my suggestions is to buy a seperator for the betta and have it get use to the other fishes for the first couple of weeks then place them together. just a heads up, doing this can cause a betta to get stressed out, so be on a look out for simptosn of ick hello!
