Okay, I have had this fellow for a while. he is about 11 months old.
Need some advice on setting up his cage, I bought him this 75 gallon about 2 months ago, and its plain jane. I want to spice it up for him. He has grown pretty fast over the past months as u can tell in the pictures. He is a good eater, nice, everything. Take a look at the newest pictures

Here is a picture from when I first got him.



Here are current pictures. I took his branch out so you could see easier. Just give me some advice, of what I could do to make it a happy environment.
