It very well could be a ruby, just an albino (or lecustic) strain. i have seen a lot of those around lately. give it a couple days and snap some more pics. Give it time to settle in. That should give us a better shot ad ID'ing it.
the first two pics look to be some type of victorian-but not sure. the second two (same fish?) red empress male-females are silver and with a black dart along the body. nice fish!
Are 1 & 2 the same as the last pics you posted? It is a victorian and looks really stressed. Next time try to get a clearer pic when he is colored. Right now, I would say a very stressed Haplochromis thick skin.
