My Tank Thread
So some of you may know that I have many tangs, including two powder blue and two Achilles.
Some of you may recall that my larger Achilles turned out to be far too aggressive for my tang tank. He beat pbt and powder brown tangs near to death one day. So I moved him to my large angel tank where my emperor and passer angels (among others) didn't take his crap. Aggressive tank. Had zero aggression issues. I then bought another Achilles this one is much more docile (like the many I've had in the past)
Some of you may also recall my powder blue "pair" that went though a quick divorce.. Tried to pair them again and it resulted in the more docile pbt hiding 24/7 to avoid abuse. So I removed the aggressor again to the same tank as the evil Achilles (who did not tolerate PBT at all initially). Figured this was risky but had a hunch that relative pecking order made a difference. In this tank there were far fewer tangs to spread aggression. Just the Achilles and a yellow belly regal.
The large Achilles was not very interested in the Aggressive PBT. Must be body language and pecking order. Towards the bottom of the pecking order, the evil Achilles is far more calm and less aggressive.
So the observation? Pecking order is a contributing factor to aggression, and I suspect body language is an important indicator of how tangs will get along since these fish have behaved differently in different scenarios.
And if anyone is curious, IMO powder blues are the most aggressive tang of all. Not sohal not even close. My sohals haven't held a torch.
