I'm almost sure its not tank breed, no offense taken, it did look drab compared to how vibrant the orange coloration was on the other ones but I liked it because it was different. The color has darkened quite a bit as I got it a few weeks ago and I would imagine that an anemone would make it darker. I can tell it would host because it tried out the hammer when it was first put in.
I've seen hybrid of true perc and black ocell b4 and they don't look similar to mine
