tang question
 

i have a pair of bluthroats and a yellow tang in my 90. All has been going well but it now looks like the yellow tang is picking on the female blue throat. The trigger is now in hiding and whenevver it comes out the tang looks like it is slashing it with its tail spikes., The trigger is also considerably larger. any thoughts??

Yellow Tangs can be nasty....and Blue Throats grow to over 10". Not helpful, but that is what I'm thinking right now.
