I recently set up a 20H with a 3 gallon inside it cuz I want to try and breed Bettas - from what I gather, you are supposed to fill the smaller tank to the top and put the female in it, then fill the larger tank a few inches below the top of the small tank. The male and female and see each other and interact and it will eventually trigger him to start building a bubble nest. Once he does that, the female will jump out of the 3 gallon into the 20H and she will start laying eggs but after that i'm not sure what to do. I can't remember if you are supposed to separate them afterwards or if they both raise the fry or just one parents does it.
Anyone with experience or know-how on this matter?
