Update:
I moved a lot of stuff around. I got a peppermint shrimp and he ate the brown plate, and then started to eat the green one. I saved the green one, and put it in my new 9 gallon. Luckily it recovered fully and is doing well in there. Really bummed about the brown one.
I bought an aqua clear 70 with a custom surface skimmer, that will be more powerful and take up less room than the one I am using now.
Also, I decided that I really like the aquascape from the side angle and is being cut off from the wall in my room, so when the new filter gets here, I am going to take everything out, rotate it 90 degrees and set it back it. Hopefully it will go smoothly considering its only two pieces of rock, but we all know how that goes.
