Ive heard thats some times they can tell the quality of the eggs maybe they werent fertile the first time idk if its 100% but i know my first 3 devil x fh spawns had my male ate the eggs after about 10-15hours they were all white, so i know none were fertile, i think it could be possible they can tell the quality but thats un for sure, but still i hope you get fry next time! My short body red devil is fertile there eggs tonight!! i hope your spawns soon id like too see some fry pics!!
