Why are they called hybrids? In stead of crossbreed, fullbloods, purebeeed?
Are they all descendants from a isolated tilapia species, that adapted to being in a niche formed by plate tectonics,?
Any of the riff lakes could have a massive extinction, earthquake, volcanic activity.
I have a hard time remembering, all the scientific names on the 300 plus Malwai cichilds.
It will be interesting to see which crossbreed eventually dominate the Florida swamps, or the Phoenix Arizona niche Salt River.
