Nothing spectacular and nothing fast. They will not fight!! If the water is too warm (Bettas are tropical) the goldfish will have its metabolism racing and won't live long. If the water is cold and suits the goldfish then the Betta will slow down and eventually its organs will stop working and it will die.
Betta fish are best as a solitary fish and are not compatible with goldfish.
yes because once i got a betta fish and i put in a tank with a gold fish the first day the betta killed the goldfish so i boult a nother goldfish it did not kill the goldfish because i put them in sepret tanks so that's what you guys should do it because i did it try it people your goldfish will not dy. my goldfish was a fin-nipper that's why it killed it because the goldfish ripped a fin off of the betta so do not put betta fish with goldfish because you never no if the goldfish is a betta.
Do not, no matter what put a goldfish and a betta together unless you want the goldfish to die!!!
You should not put a male betta with goldfish's.They are aggressive and will fight with goldfish's goldfish give off ammonia and will kill the Betta's.
Betas are very aggressive and will attempt to kill the goldfish. Also goldfish are a cold water fish that produce a lot of waste which could be harmful to the Betta.
Coldwater fish go with Goldfish (temperature under 70F). Tropical fish go with Bettas (temperature over 70F). Just make sure that you don't put any more than one Betta in a tank. So Bettas and tropicals don't go with Goldfish and vice versa.
No, betta fish are tropical fish; goldfish are coldwater fish, this should be reason enough not to mix the two. The mixing of these fish would be irresponsible and could yield distatorous results. One reason not to mix them would be because betta fish are quite small; most don't even reach 1/3 the size of a goldfish (even when full grown!) it makes them very likely to get bullied by the other fish. Fin nipping can be a major problem and is dangerous for the health of the fish. Do all your fish a favor by not mix betta fish with goldfish.
Gold fish require water below 70F and Bettas require water above 75F so they should not be kept together.
A betta prefers warm water, where gold fish like cold water, also male bettas prefer to be by themselves, also a betta prefers a shallow water where gold fish prefer a deep tank, gold fish need a filter and bettas do not.
No you can't. goldfish are coldwater species while bettas are tropical fish.
You could put platies, tetras, corydoras, oto cats, guppies (non-fancy), danios (glofish), shrimp, snails, mollies, swordtails, barbs, rasboras, and African dwarf frogs. I would not recommend putting goldfish with Betta fish. Goldfish are carp, so they get pretty big. They also can give out large amounts of ammonia. Goldfish are also coldwater, and betta fish tropical, so they won't mix well.
um, i think i wouldn't if i were you cuz goldfish and beta fish need different nutrients
