I found a lfs by me that carries pretty much any fish sold in the US. If they don't have it, they can order it and have in a week. They have a hystrix for sale. I signed up for their membership so I receive 25% off any fish. The hystrix would be $189. I did not pick the hystrix up today, because when I went to see him/her he was pretty white. He had the "hystrix" patterns but most of the ones I've seen were much darker. Do they get darker as they mature? He was healthy looking, very thick just didn't know what was going on with coloring. He was also on white gravel, not sure if that has anything to do with it.
