In actuality there are only 3 species of rams, Mikrogeophagus altispiniosus, M maculicauda, M ramerizi.
All the blues, golds, pinks, long fins etc are not separate species, just aquarium variants and color strains of the 3 same natural species.
Just like red oscars, blues, copper, long fins are not separate species of oscars, (although there are a number of sparate species of oscars)
the ones listed above are just in-bred aquarium color strains, produced by aquarists selecting for certain colors or shapes, and can all interbreed.
Just like guppy breeders select reds, fan tails, black etc etc, they are all just fancy, man induced color, tail shapes variations of guppies
