I have kept and bred chocolates for years, it started with a pair I got from lfs about 4 years ago, the owner said they were a pair but they never bonded or spawned. I got a pair from Rapps 12/06 and the spawned at about 4-5" and even though the male has passed the female is only 7" I currentl have a few dozen f1 adult fry from the pair, check my ad "chocolate cichlids" for pics, I'll bump it up. I think my domestic chocolates grew a lot larger. I currently keep from 6-8 adults in a 125 gal with C Micrthalmus 5-8", a pair of green terrore 5-6", a pair of FO P. freddies and they spawn constantly with mild agression during breeding. I have kept chocolates with many types of cichlids mild and agressive, the thjing I appreciate the most about them is the fact that they get along well with everybody. I have yet to have to remove a chocolate due to violence. You will see from the pics that I have a lot of experience with them. The one exception is the lone FO female who lives in my 180 gal with an insane male grammode who is extremely agressive, I only see her at feeding time when she leaves her cave but no cuts or scratches. I had a lot to say but my experiences are different than what I was reading. If you would like some good quality chocolates let me know.
