i have an auriga butterfly and a PBT. The auriga was in the tank first and when i introduced it, the auriga harrassed the PBT for 2 days straight. It actually scratched him with it's top fins (they are sharp!). After the PBT got acclimated, it started harrassing the aruiga. It now rules the tank. Looking back, i would not have these 2 fish in the same tank. I am lucky that i introduced the PBT last.....if you add the auriga after the PBT, i imagine it will harrass it to death (JMO
). It can be NASTY!
They are both beautiful fish, I have a 125 gallon and got lucky, again i would not have these 2 in the same tank again. I also have a naso that is indifferent to the PBT and visa versa. BTW
.......I know you are going to, but add the nori ASAP
, as tangs are herbivores. Mine eats anything, but don't over do the meaty diet.
