Help with Wolf fish

They can change their coloring depending on mood, lighting, etc. Mine shows anywhere from a light honey tan coloring all the way to almost jet black depending on mood.
 
I have done it. I had two, one was and is very fish aggressive and can't be kept with anything. The other I mixed with various fish, only issues were similar shaped fish that shared the same territory. This was in both a 6' and 8' tank, I personally would try it in anything smaller than a 180
 
There are lots of posts in "other Characins" on Hoplias species. Really a nice looking fish. How big and how long you had it?
