So the other day, I bought my first Betta, Odysseus. As seen in the title, he's a male Crown Tail, and he is very pretty. I have him in a 1 gallon alone, but I was wondering if I would be able to add him into my 10 gallon. There are 3 platys and 2 guppies in it.
I have had mellow bettas with guppies and platy. Platy sometimes can be nippy - but ones I seem to find are scared of bigger fish so leave them alone. Guppies, usually do not mind, but there are some mean ones - and some bettas take offense to male guppy colors You can try. I'd float him, for half an hour, see his reaction (flaring is not good, especially if he does not stop flaring when the half hour is over!), then introduce him. When introducing rearrange ornaments and fake plants. This makes the territory no longer a particular fish's (like one of the platys may "own" a plant). Make sure to keep an eye on everyone! Check fins constantly for ripped edges. Look for stress signs!
That's okay :) I got two males in 1 gallon tanks, but trust me it is okay for some bettas as there are bettas (I have them!) who hate large spaces, but I have most in larger containers or tanks. If your guy is like my Spartan you will have no problem! Expect some chasing, a little nipping from him if anything, then afterwards it'll be fine. If he doesn't stop chasing, then there is a problem. Good luck!
Not just yet :) let him flare. it's kind of an establishment. My Spartan did it too ^^ then he didn't care. I have had that fishy with guppies, both genders, balloon mollies, danios (leopard), long fin danios (one tore his pectoral fin >/), platy... Try for half an hour like I said :) then you will tell xD
He's probably feeling a bit overwhelmed by all the space. My new boy came into my 5 gallon tank from what was probably a 1/2 gallon max, at the shop, and for the first day I barely saw him at all. The second day he would swim around if he thought no one could see him. Now he loves it and I can't imagine him in anything smaller. :)
