Crenicichla id, zebrina?

[NHKG]

I sold this fish one year ago. They were killing tankmates (20cm Satanoperca and Pimelodus ornatus). And I saw them bite off pleco tail fin. 6 feet tank was small for them. I wish I have bigger tank. I miss them.
I saw price list from German wholesale. They are offering 5-7cm Crenicichla zebrina for 100$ per piece! And they have more than 40 fish for sale. Is someone breeding them?

Maybe they have figured out how to breed them (hormonally induced?). A picture of the juveniles could confirm it.
