Wow, Cool video! I'm glad to see the fish I sold you are going well. It is interesting that the male d. comp is pwning my livingstonii. So many people told me not to put a comp with my nimbos that they could only survive if they are fast enough to escape the nimbos beating, livngstonii in particular and here we have two adult and d. comp comes out on top. Then again they say Fuscos are the most aggressive nimbos (should be tyranochromis) and the 2 i had were punked by my livingstonii, venustus, and polystigma. Just more proof that cichlids are individuals and aggression can vary.
