I am going to feed the eggs for month or so and see if I can get them laying on a tile, funny I have had them under a year and moved them a week ago from my work tank to home, they spawned within a week of the move, i did change their diet to my shrip, scallop, squid, cyclopese, and formula one mix, with some small specs of nori which they love. When purchased they were the same size, they are tank bred fish from thailand.
