Alright a LFS by me has a bunch of really nice good sized dollars and some tinfoil barbs that ive never seen before. The other LFS I go to has a payara in I have to get a pic to put on here for an I.D. but other then that one payara I have NEVER seen one anywhere close to me
If you can give us a price we can more than likely guess what it is. Scombs usually go for around 20 when they show up at a LFS. Tats usually 40-70, and Armatus can be all over the map. Chances are though it's a Scomberoides. Get us a pic and we should be able to get you an ID though.
