I mean if one of the fish cannot be breeders anymore than you can transfer them to a community tank if you have one.
To the betta experts: How do I tell the specific cause for my new male betta's curled fins? The edges of his fin are rolled up a bit, and his ventral fins are curled up. I know there can be different causes, like lack of space, bad water quality, bad genetics, fin rot, etc. but is there any way to tell the specific cause? I can always wait it out, but I don't want continuous waiting to delay my breeding plan in the future(especially if I'm waiting on something that will never change).
The water conditions are the same as before(you can go back a page or two to see my post). I can find it and re-state it if you like.
I should've elaborated; it's the new boy who has it, and he just got introduced into the tank. It's possible that the previous water conditions in his cup were terrible, I'm just wondering what he has and if/how I can fix it. And I'll be sure not to keep bettas and guppies together, which I was considering... close one!
