How many fish in a 50?? :)

[Aquattro]

no worries, the velvet is a month ago, so just restocking fish so I can treat them all in quarantine before restocking the 180g. Not ideal, but I got a deal on some fish that I couldn't pass on, so I've got to manage them for a few more weeks in the smaller tank.
I forgot, I've got a purple tang coming too, although that one might be able to stay where it is for a few weeks.
