Thank you for the info about the egg crate. I'm going to pull it out. My favorite fish is my Jawfish and I am not willing to risk his safety. Since the glass is so thick, and the tank is not that deep, the chances of a rock falling hard enough to shatter the glass is nil.
As far as fish I have some fish from my old 150G tank that Matt from Sho Tank Aquariums is taking care of for me while my new tank is cycling. I currently have a Flame Angel, a Dusky Jawfish, an Ocellaris Clownfish, and a Yellow Tail Damsel. I might just give Matt the Damsel as I am not sure that I really want to put it in my new tank.
I am really not sure what other fish I will be able to add in the future. I definitely want to add a Royal Gramma. I have considered adding a school of Chromis but I am not sure on that as I am not a diehard Chromis fan. My wife loves regular Cardinals but I would prefer Bangai Cardinals. I have a serious soft spot for Blue Jaw Triggers but I am not sure if a Trigger would be good in this tank. I like Kole Tangs, Blue Hippo Tangs, Yellow Tangs, and Naso Tangs but I don't know that I can have any Tangs in my tank.
