I wouldn't. Bettas don't like long in my experiences. Some people have better luck with them, but I don't. You could also add some little tetra fish, or a couple of female betta.

You could do a smaller water change if you want before adding anything.
Hi all, I bought 2 more bettas. Looked so pretty in the store but after I got them home they dont really show up in the tanks.
maybe try adding a lighter background or substrate? Or a tank light or plants or something?It must be the background. Its black. The fish is a dark blue body w/ lighter blue fins. double moon tail I think. The other is blue and red.

I’m hoping once I add the plants and lights though, he will show up better lolYour tank where your fish died, If by chance it did have anything (slim chance) I think waiting a couple days would kill anything in the tank.
