How Big Will Pygmy Corys Be At What Age?

I am just curious because I have other fish I would like to breed, and this is my only designated 'breeding' tank at the moment. My Pygmy Corydoras are about 2 weeks old and I can see them, but still definitely too small to move them around to another tank. They are the first egglayer fish I have bred successfully and I'm curious as to what age will I be able to see them clearly and would they be able to be fed as a 'normal' adult fish would be. As I said they are about 2 weeks old and I have counted 7 in one spot at once, so I am assuming there are more, but not sure yet. Will include picture for reference of size to adult.

 

I can't tell you how fast they will grow - my guess is it will take 2 or 3 months to get a 1/2 inch but that is just a wild guess on how fast other frys i have have grown. They start out slow. If you want to sell a few when they get to 1/8 to 1/4 an inch drop me note I can grow them out once they are old enough to ship... Well not all i only need 4 to 8 (I have 5 or 6).

 

Hmm maybe down the road I will be selling them, but for now I only have 5 adults, 2 females and 3 males, which I got about 3 months ago and I am trying to grow the herd here. I actually plan to breed them until I get a bigger colony in a 20H so I can breed some and have some in the community tanks, but right now they take up my only 'breeding' tank. I have cardinal tetras and black neons ready to breed, just these cories are what I'm waiting on. So maybe once I get 50-100 of these lil guys I won't have a problem selling breeding pairs of them off haha. My plans are to get more cories to breed, like salt and peppers and black cories are really on my list, but space and money are limited lol.
These babies have basically been eating the natural water flea colony in the tank already and frozen baby brine since hatch, is there anything else I could feed thats better for them?

 

Not sure i've only done angels so far. I'm not looking for more to breed so sex wont' matter
-
As for cory orange laser are a pia to find - breed those
-
I have about 20 sterbai - one of these days i'll beat the apistogramma to the eggs and try hatching those.
-
I can't help with feeding cory - i've been told they can eat whatever but i've never raised them - they don't have to be as prot. heavy as other fishes might require. Hikari first bite might work with them.
-
bbs is the thing for frys that require movement to eat - also vin. eel and micro worms. But if the fish will eat stuff that doesn't move i'd definitely go with golden perl, hiraki first bite or similar.

 

Yeahh I have thought about orange lasers, but they are kinda the 'mainstream' uber cory. I wanna go with stuff people don't really think about right off the top of their head and when they see it in a big group they go 'ohh I need 20 of those, I've never seen that before', plus I know in my area a lot of the people big into fish are looking for black cories local bred.
