Hap's is a happy fish, has a nice pretty tank and is obviously well fed. I've had a few fish in my time. At 1x I had a large Saltwater Aquarium full of fish Coral and rock. Fish when they get used to you are very friendly. In fact you have to make sure they don't try to jump out of the tank to follow you when you leave the area. I used the decimate modifier to lower the poly count. Next I'd like to learn how to animate him.
