Is that a Butterfly Pyramid or did you mean a Pyramid Butterfly (Hemitaurichthys zoster)?

Is it normal for the pyramid butterfly to attack a yellow tang which I bugger then him.

Zoster Butterflies can hold their own against a number of fish. I wouldn't worry about it unless the fighting gets to the point that someone gets hurt or is constant.

Hope this helps

I'm worried about my sick tang , the butterfly is fine

 

[Ferny27]

I have never seen him spike his fins an attack another fish bedore

Is he damaging the yellow tang? Like is he constantly going after it?

Those spines are SHARP too!

Yes he is, he stops for a while and then he keeps going. He has been here for a week now and it just started today.
