hi there i have a 6ft 125 with a pair of angels that i am hoping to breed. The tank inhabitants are 4 electric blue acara, 6 giant danios, and 3 other smaller angels. The pair that is in the tank are a known pair that i got from a great LFS who had a breeder that is leaving the hobby drop them off. The breeder housed them in a 40 breeder with a pair of rams. When i picked them up they were breeding in the tank and had only been in the store a few days so i know they are still breeding and not too old. I've had them for around 3 months and nothing. I've tried raising and lowering the temp, big water changes, put some new breeding spots in and nothing. They keep to themselves and don't bother anyone else and don't get picked on. I'm just wondering if there's any other tips other than putting them in a separate tank that i could try.
