Prejudiced Platys?

[Guppers]

Do different types of platys ever ignore other strains? I have 3 platys...two are iridescent greenish with either white or orange on their heads and tails, and the third is orange/reddish. The two greenish ones are almost always swimming together and the orange one is usually swimming up and down the sides of the glass looking at himself. He never interacts with the greenish ones. Actually, his body type is different too. The orange one is a deeper bodied fish, while the other two are smaller and more slender. One of the greenish ones is female, so I assumed the orange one...being a male, would chase her around a bit once in a while. Instead, he ignores her very existence.

Any ideas on what is up with the platys?

It appeared that you have two different species of platies. Two black slender bodied ones are Variatus Platy (Xiphophorus variatus) and the red one are Southern Platy (Xiphophorus maculatus). So they are very different species through they can hybridizing each other, just not so readily.

It appeared that the black/orange variatus is male and the black/green is female. Maybe the variatus male are dominant male in that tank? The variatus male always harassing the female one so you need to get another female variatus for him too. Plus get two females for the red male too. As livebearers rule is that you always use a ratio for sex is 2-3 females per male. So the females can be a little relaxing for awhile since males are always being horny all time.

Platys can be very choosy with each other and sometimes just will ignore and never bother with each other, they will breed with each other eventually but it can take time.

You really need to have 1 male to every 2-3 females. never have more males than females cos your just asking for trouble that way.
