damn...i was picking from the tank and all the armatus looking ones with spots were infested with ich so i went for the guys who didnt have as bad a case of ich...but i guess i choice wrong...i had a hunch they were scombs
That is a scomb. There were a few in Jake's batch from his second group of pictures that I think were scombs as well. Armatus and tatauaia have spots when little, scomberoides and wallacei don't.
depending how severe the case was it may have been treatable. But i wouldnt have risked it either, just buying and transfering it with stress could kill it at that size.
