Thanks everyone! So, he's been in the tank for 3 days now and it didn't take him long to start remodeling. As you can see from the pics above, all that was in the tank was the ornament piece at the center... I figure having that there kind of gives him this guide to swim back and forth in laps. He seems to like the back half bare so he shifted most of it to the front. Also, when people use to comment how midas' are like puppies.... wow; I'm experiencing it first had. When my 3 year old runs through the room he seems to bolt across the tank like he want's to chase her. I'm not sure if he just want to bite people's hands off or if he's just saying "Hi"... but he does a good job of being the room's watch dog.
