How grown are my Auratus?

[L021]

Pics below, they're in my 55, I know they're supposed to grow from 4-5", but frankly I don't really know how big that is, I have trouble with size, considering they're in the tank and all. My question is, do the bigger ones look like mature fish, or do they still have some good growing to do? I've had them for about 5 months at this point I think.

Really no way to tell how big they are right now from the picture, but other than the males changing color when mature, the females will look just like they did when babies, but bigger. 5 inches is about half a dollar bill.

those are only 1/3 of what they will become
