Angel fish question

It should be easy to tell what ones to get out because 2 of them will start picking on the rest but like I said when its time you will be able to tell
 
Thanks much for the advice, might be time to get the smaller ones of the 6 out. (4 are a couple of inches across and 2 have bodies about quarter size or so.)
 
Just an update.
So far so good. I've had to move the smaller of the larger angels to a friends house, it was getting smacked around a bit and was starting to look a little rough so this leaves 3 large and one small (the other small one didn't make it. I think it didn't tolerate the last water change to well) aside from the Corys, mollys, and the Plecostomas.
Today I noticed what I think is eggs on the back glass (small whitish round things stuck to the glass) not sure who put them there though. How large do angels have to be to start laying eggs?
 
it's more about age/maturity than size.

domestic angels may begin laying eggs as soon as 6-10 months.

I have seen small (stunted) angels lay at quarter size.
 
The biggest angel in the tank is about 3 inches from nose to just before the tail starts and the smallest of that group is about 2 1/2 inches. The littlest one is almost quarter size and always hungry lol!
 
If the eggs stay a tanish color then they are fertile and should hatch.

However this being the first spawn it unlikely to be successful. It usually takes the 3rd or 4th spawn till they get it right.
