How many fish in a 50?? :)

[toytech]

I have a picture in my mind of a bunch of fish all squished against the glass with fins and things sticking out fo the top of the tank .As for whaterchanges i would just regularily test nitrates and do waterchanges acordingly to keep them at a level you deem aceptable .The thing that would worry me with that many fish would be O2 saturation , but you must be running a good skimmer so it should be ok. +1 on a picture , bet it looks awsome.
