When I got him he came on a perch much bigger than what I have in there now and he perched on it. The tank isn't very large either, 18 inches wide by 24 tall. Should I still add something to make him feel more secure? Also, how can I lower temps? The day light bulb is a 100W, the night time bulb is a 75 watt.

The issue with adding more perches is that I'm not sure how. This one was a total pain in the ass, I had to buy a plunger, cut it to size, then use mounts to get it in there. I have no clue how to attach perches to a glass sided tank.
