I have two baby Hermans.....I think your tank would probably be okay temporarily but they need lots of space to run around in so I wouldn't keep him in it for too long. Make sure you cover the sides of the glass...if they can see out they will be constantly pushing against the glass to try and get out. I spinkle a little bit of reptocal and reptivite on there food twice a day. Also make sure there is a shallow bowl of water in the pen at all times. . They can easily climb in and out without tipping over onto there backs. And of course the UV and heat lite on one side of the tank....keeping the other side of the tank cooler. Good luck!!! They are fun little guys.
