I have a maroon clown (pretty aggressive fish) and had a potters angel for close to 2 years living just fine in my tank. Unfortunately where I live we had a bad heatwave last summer that lasted over a week and I couldn't keep my tank cool enough. My only fish I lost was the Potters Angel but I lost 75% of my corals which was a very expensive loss. When I bought my Potters my LFS had not really heard of them and just got a couple in to see if people liked them. They cost $30 at the time.. now that my LFS is seeing a huge demand for Potters he has raised the price to $75. I decided to go with a Pygmy to replace the Potter due to the price difference but I think the Potters Angel is by far the best looking Angel out there.
