Definitely looks like a silk and a gold base. I've been observing my gb growouts and pretty much every female that has decided to lay eggs and spazz out on everything else in the tank did not have the fins trailing back like the one in pic. Best way to find out is to vent. They may be big enough to be able to do it.

This are hard to sex at there size. Grow them out for few more months. Your golden base have a potential esp the pearls on the head and face. Enjoy your new flowerhorn.
