This guy is unique, you don't see alot of orange on three beacons...He's current 8-9" becoming a monster, can't wait until he hits over 10". Hope you enjoy the pic.
Wow, that really is a beautiful dragon fin L91. Mine doesn't have as much orange on the dorsal as yours, but I think mine has a little more orange on the caudal. Any idea on sex? It would be cool if someone really focused on breeding the dragon or tiger fin varieties of triactis. I keep meaning to post a pic of mine; I'll try to remember to do it tonight.
I've seen it very infrequently on aquabid. I got mine at a local LFS (Congressional Aquarium). I just went in, and saw it and lucked out (and luckily had a 50% coupon too). I would love to get another one, though I'm not sure the 56 column is big enough for 2.
