They arent GATF. I did consider Forskalli but Forskalli as well has very dark stripping. I'm still sticking with Brevis. Sorry man I hope your not too bummed about it.
Definitely not a Goliath and not the common Vitattus I've had in the past. I had a few of those back when and bought them as Forskalli's. Much more slender, small snout, big head. Most have said in the past that Vitattus & Forskalli are the same so could be Brevis.
Why don't you like these? I would keep these boys and grow them out. See how they develop as they get bigger. VATF's are a dime a dozen. These guys you don't see often.
