umm well just get a net and move him from one tank to the other
A male beta fish blows a lot of bubbles. so if there are a ton of bubbles at the top of the bowl or tank, your fish is most likely a boy.
put it in a tank with another male betta
well... i think i have gotten my male to except two other females by putting them in a bigger tank. ( i have 5 gal. tank) or i think i had gotten the male to except a female by putting them in a smaller devider tank (half gallon) if your asking about breeding them... i havent found out how to do that either. heh heh
The male will kill the female after he spawns her. If she won't spawn he will still kill her. No male Betta will allow another Betta (male or female) to live in its vicinity. So the answer is NO.
You should not put your Betta fish in the same tank in the first place, most likely the male will kill your other fish. by res do you mean red eared slider?
it depends i have a male with a female betta, in a 2.5 gallon tank,they get along, i wouldnt risk it, no
None are recommended if the Betta is a male.
If your tank is too small for a heater it's too small for the Betta. The answer is simple. Get a bigger tank. A male Betta needs a heater, a filter, a light and living plants to be healthy. It grows to about 2 inches long so that means it needs at least 2 gallons of water ie a 3 gallon max capacity tank.
Male Betta splendens fight with other male Betta splendens so the answer is most other fish will not fight with a Betta in the same tank. To try to list every species of fish here would be impossible.
keeping multiple bettas in the same tank is not reccomended
== == you can't put to malebettas in the same tank together because they are Territorial fish and they will fight until one badly injured or dead. But you may be able to buy a divider for your to keep to bettas.
Any.
