2/3/4/ days fanning, but she still used the shell when the little eyes started to appear and then guarded it for ages. Once the fry leave the shells and crawl around the tank remove them as the male may eat them ( I caught mom at it as well), So I had these 2 shells about an inch apart right at the front of the tank with a female fanning in each, SWEET.
