Nope, but I wouldn't think it'd take long. I can go to bed and wake up and there's one in the tank. But I've never bred bettas, or anything to be honest (except guppies, but they don't require anything special to make it happen).
My betta builds 'em when he's happy. I'm gonna get him a wife as soon as I am told whether she can go in my community tank or not.
so here is wats going on i have the tank full of plants for her to hide in and for him to build under!! BBS cost a penny and a dime for 30 of them so im good
i have another question! this is the only thing i do not know! when will i need the seperate cups?!cause im going to put them all in individual 1 gallon beanie boxes!
