Can I put two bettas together in a 10 gallon tank?
I want to transfer my red male Betta from a 1 1/2-gallon tank to a 10-gallon tank for some fancy guppies I want to put in the smaller tank. Can I put two Bettas together in a 10-gallon tank or will they still fight? I have heard something about if they are in a larger tank and maybe put some other fish in there that it would be okay. Just want to be sure before I do that. If not, what are some other fish that would go great with my fish?
I've read a bout the 2f to 1 m idea, however a couple issues there are domminant female being aggresive toward the other, jelousy(to girls fighting over a guy, hey fish do it to), or the fish might just not get along( even if they are a docile breed of Bettas)
I can imagine a 125+ gallon tank working fine... the reason that a 10 gallon wouldn't work is because the fighting males wouldn't be able to flee far enough, spending time miserable because of stress. 125 gallons, though, is plenty of space to lose a pursuer and de-stress. Females can flee males, males can flee females, males can flee males, and females can flee females. The amount of space is key. And 125 gallons is a LOT of space, lol. So I wouldn't say that males can NEVER be placed together, but you MUST, MUST, MUST have a large, heavily planted tank with multiple hiding spots.
But to answer the question, as the others have said, no, you cannot place two males in a undivided 10 gallon tank. It would pretty much assure death. Don't believe youtube.
Most of the posts above sound reasonable. But to do so in a 10 gal just simply divide the tank. 5 g is a pretty decent amount of space for a betta to live in. I think you can buy dividers at a store, or maybe you could make them...?
