Do water changes everyday. Keep the water quality up. Feed high quality frozen food. Mine like frozen bloodworms. Yours should lay eggs again in about 10 maybe 14 days. Your pair is young, so it might take them a few try to get it right. I am getting out of breeding angels and have two breeding pairs to sell along with 6 adult angels. If you know of anyone, please email at . Email me if you have any other questions about breeding angels.
