Flowerhorns are cichlasoma hybrids. Its hard to tell whta fish went into making individual flowerhorns. Synspillum, trimac, devil, fastae, texas, blackbelts, temporelis some of the more commonly used for crossbreeding. It takes a long time for them to mature, I don't think you have adult fish in a 30gallon, Its pretty hard to get a mated pair, and often if you do get a spawn the eggs will not hatch. If you do get a good spawn and fry, 99% of the time the offspring look nothing like the parrents. I hope this helps you

I didn't say they will not breed, I keep and breed flowerhorns and if you get one fertile pair out of 10 is great. You need a large tank 75gallon or so. When they spawn, just like large cichlasoma cichlids they will beat on eachother,
are there any signs of them beeing a pair? How large are they? and how old?
