I've got one. Fun fish to watch. In my tank I have 2 false percs and the angel. He seems to be the shy and least aggressive one of the group. Spends all day eating algae off the rocks and sides of the tank.
I'm by no means experienced with fish keeping (I've only had the tank for 2 months), but I hear that angels are really sensitive to changes in the water so that might be something to consider if you are thinking about getting one. Overall, my experiences with him have been great. He's a good eater and doesn't bother anything in the tank. I'd recommend one in a heartbeat
Here's my website if you want to see some pics of him. <a href="http://www.geocities.com/coolsammy88" target="_blank">http://www.geocities.com/coolsammy88</a>
