It wouldn't hurt to put a nice piece of plywood on top to provide a flat level surface for the tank to sit on.
If it's a glass tank with a rim the top won't matter a hill of beans. The tank only sits on the edges. Putting a nice piece of plywood will only appease your own mind. The tank won't be resting on any part except the edges. You don't even need a top at all. Just 2 x 3 framework will take care of it just fine. If he doesn't put a skin on it I would wholeheartedly recommend X bracing to help prevent racking. 2 x 4 legs are more than adequate. Don't use pressure treated on any part of it.
