Agressive bi-color

[fishytime]

From the title you-all are probably thinking Im gonna refer to the bi-colr angel I have, but actually its my bi-color blennie that is a little turd. Some of you may have read that I recenlty added a 5"ish powder blue tang to my 110g. It seems like the most easy going fish I have and doesnt bother a thing.It probably doesnt see any of the much smaller fish in the tank with it as a threat. Except for my bi-color blenny( which is maybe 2"). The BB will be sitting there in a little hiddy hole and when the powder blue swims by he rushes out and bites it in the arse(tail) and then quickly runs and hides. Which absolutely infuriates the powder blue.Ive seen it a few times now while staring at my new addition.The blenny hasnt done any damage that I can see, so I think it hilarious. What cajones this little bi-color blennie has.
