I am new to betta breeding so please excuse me if my questions are dumb. I have a crowntail female and a crowntail male who I both conditioned for two weeks. I put them in my ten gallon breeder tank (6 inches of water, a half of a styrofoam cup, a glass vial for the female to reside in, and a sponge filter). The two fish have been in the breeder tank for about 4 days now. They are both showing interest in each other and then female now has the vertical stripes. However, the male has not built a bubble nest. Once both fish are in the breeder tank does it usually take more than four days to build a bubble nest? What are the average time periods for the ale to begin building the bubble nest? Thanks in advance!
