How many Albino Cory's can I put in a 20 Gallon Long?

[sandman76]

Hello, I just upgaded from a 10 to a 20 gallon long tank. I currently have 3 Albino cory's in there. My intent is not to breed them, however if it happens it happens. I also have 5 Black skirted tetra in there and am looking to put 2 more 2 inch fish (community) can I finish the school of cory's and put 3 more in, making it 6, or would I need bigger tank.. would there be any merit in putting in maybe 1-2 more if 3 is out of the question? thanks for your help. My 3 are about 2 inches long, and the new ones which I would be purchasing are about 1 1/4 inches. Thanks again.

I had 12 peppered corys in 20 long, solo occupants. if that helps.

In my opinion I do not see a reason for not doing as you wish. They should be a happy little group.

I have to say it is always a good idea to isolate new fish for awhile.

At the very least make sure they are in very good shape if you are just putting them in with the others without isolation first...but then it is always a gamble.
