That's a TATF. A bit unusually colored, but a tatf none the less.
There is a precident of tanzies having this coloration in blue background, light substrate tanks, which this appears to be. Incidentally, this is also the coloration they show when they're caught in clear water with white sand bottoms in the wild.
The dead giveaway that this isn't a brevis is the fact that the adipose fin is solidly colored. Where it a brevis, it would have a distinct, sharply bordered lighter outer edge on its adipose fin. Tanzies and vittatus lack this.
This fish is a prime example to show why I call tanzies "vittatus heavy". At first glance I thought it may have been a brevis as well. A large, healthy tanzy can approach the beefiness of a brevis or goliath.
As I've said before, a tanzy is a vittatus trying its best to be a goliath...
EDIT-
I'm positive it's a VATF. I got it from Jeff Rapps 1.5 years ago at 4" when he imported a whole group of VATF.
That was right about the time when we as a community were just starting to figure out the difference between tatf and vatf, so I'm not surprised to see that it was mislabeled and we certainly can't blame Jeff for it.
Heck, even now it can be nigh impossible to differentiate between the four non-goliaths at small sizes, even for me, and I wrote the guide!
