Also my local fish store once had A hydrocynus vittatus I decided to wait a week to buy it, came back it was gone.Same with a tsn that i decided to wait and buy it was gone. Boy ive been looking for any species of african tigerfish, but have never seen one for sale again.I consider those fish rare, but people get them easier than me and just keep buying them cause they dont have that one. Like the any bagarius that people want to buy because of their rarity, but than u end up with 3 fish that sits their and does nothing whether than 1. You should just be happy with the one new fish u just got and be proud how rare it is.And be happy with your current fish stocks.I have a Silver aro,jag chiclid, and indo pacific tarpon which i am specificly proud of.
