Mixed breeding

there are fish that will breed with other species ie the flowerhorn cichlid and the blood parrot cichlid.

This matter is the subject of intence debate in the fishkeeping world, so Im not going to go into it. But what I would say is that there are HEAPS of other fish that can be bred with their OWN kind, the results of which are normally interesting, eductional and strait forward awesome.

Look at almost any Xiphophorus individual, and you will likely see the results of Platy/Swordtail interbreeding.
