So recently we identified my tigerfish as a Brevis which is arguably one of the most aggressive species. I have also heard that tatuaia payara are also considered the most aggressive of the payara. Now neither of these species inhabit the same waters, however they are both specialized to a very similar biotope. While the tigerfish grows larger, the tats school I have a school of 3 tats and a single baft allbof similar size tats 6.5-7.5" and the baft is 6.5" will they squabble and find peace or will I wake up one day to a blood bath?
