Kole tang
 

So here it is........I've had a Kole tang in my tank now for 3 months and never had any issues. Yesterday I added a power head and scape my rock work a bit to head the power head, now the tang has gone mad he constantly power swims at the new pump then goes on top and flicks it's tail at it. Do they like strong currents sometime or is he just ****ed that I added that power head and trying to attack it. I had never seen his defensive spines before I added that pump. Whats your thoughts?

I have seen tangs attack new stuff that has been added to the tank and it is also well known that they like to play in the current created by powerhead's.

Try to put a mirror beside the power head that should take the tangs attention of the power head and onto itself.

Thanks for the info...he'll soon realize he can't win that fight and give up hopefully.

Hopefully he doesn't make it into the powerhead before then and meet that really fast spinning thing :wink:

Wife figured it out...I removed the black background I had placed and within 5 minutes he was normal once again.

It could be just getting some excercise, they are known to swim into the powerhead for that reason. It wierd that its flicking its tail at it, that seems like aggression.
