I had a wild Andinoacara latifrons attempt to breed with a Cichlasoma amazonarum, they spawned together multiple times over a period of a few months. The eggs never hatched, but I later found out that both of these fish were females so that wasn't really a test! Later the same blue acara tried very hard to display to my (also female) severum, who ignored her. I have seen reports of the electric blues breeding successfully with normal blue acaras and as Jexnell said they would probably be able to breed with green terrors too.
