I got a pair of betta last week from Petco. One male Delta tail and one female veil tail. I put the female in a cup inside the breeding tank. The male had just started on the bubble nest when the female jumped out of the cup into the tank. They are not hurting each other, just flaring. Is this a bad thing or does it matter at all that they are in tank together. Should I take the female out?
Also, the female has a black horizontal line all the way down her. Is that common because I have never seen it before. I am sort of new to breeding bettas...haha
