here is a shot taken during my weekly tank maintanence.
Think originially i did post something about 15-20 should not be a problem whilst not-fully grown.....
as you can see i have about 30-40 in the tank, but they are certainly NOT fully grown...
I stripped the tank down as i was about to add a nother dozen fish, which comprimsed of 2 saulosi, two elongatus mpangas (all 2.5" WC) and 8 little petricolas..
I certainly won't have a tank of 30-40 full sized fish in the tank, and hope that at some point during the thread it did say this.. but if not I'll say it again
Overstock when young, so you can get the fish and sex ration right and thin out as they grow by removing 'extras'
i would personally hate to have a tank like mine (or yours) with only 10 juve fish in all the time during whilst they are growing (which will take a couple of years btw) just so i don't mess around with taking them out at as later date..
besides - you'll change which fish you want a thousand times in your mind, best to get them if you can ( and they are compatible etc etc) and make your mind up with them in the tank right in front of you
