My Crazy Apistogramma - MacMasteri & Cacatouides crossbreed

Apistogramma are my most favourite fish - their character, their looks and their amazing behaviour can keep me watching them for hours.  During one of my hour sessions of watching I discovered my Macmasteri female heavily flirting with my Cacatouides male!!!  What is going on?   They even took it a step further and she picked a corner to breed in with him...  I managed to capture their illicit affair on camera and it shows quite nicely the pre-mating flaring and behaviour as well as the chasing off of other fish not matter how big.
