I have 100 tanks, most of them are over 175 ltrs, I breed lots of angels, Australian rainbows, Apistogrammas and catfish. In recent years I have bred Cichla Uaru pollini and balzanii. I am currently working with 1 pair of senegals 1 pair of dalhezi 2 pairs of endlicheri and I have a male ornate. I'm after a female ornate but they are hard to come by in Australia. Most adult Polys go for $500+ here because we cannot import them. The Senegal pair are at least 6 years old and have been spawning for about 4 years, the dalhezi spawned 3 times about 3 months ago but I think the male is too young so I didn't get any fry.

I can't say if they will spawn or not, 6 month old senegals can reach 9" if kept in a large tank. I believe they would have to be at least 2 years old to breed, if you don't know the history of the fish you can only guess at its age
