You should def. do some research on the fish before you buy. They all WILL outgrow that tank, even one will.

Yellow Tangs tend to be very aggressive in groups of two. Did you try turning your lights off for a while? This could cause them to calm down a little bit.

Its very common for some fish to fight their own reflection.....not much you can do to stop it that I know of except put some white parer on the outside and sometimes that does not work either .....hopefully they will calm down and do it less....if the stress gets to them then stress will do what stress does. Cuase them to get sick.
I have a Hippo and a few Yellows and they sometimes fight themselfs still after 6 years....it is funny at first but after a while.........
