Even though you are good friends with him, I still don't think you should order any fish trough them. They have a bad reputation for fish for a reason. Even if he knows what he is doing he isn't the only person who takes care of the tanks, so who knows what crap is in them.
Also if you order them whos to say he will be there when the aros arrive. You could have some dumb kid who doesn't know a pleco from a guppy handleing them when they arrive. Plus it would probably be your luck and they arrive and they don't call you can they end up cramming them all in one tank with a bunch of other sick fish.
If you want one that bad, I would advise ordering one off the internet or, buy one from one of the sellers here.
Just my 2cents.
