Another Question!

Just curious, does a blue gourami's color become more vivid when they are confronting another fish over territory? I have been noticing that when one of the gouramis leaves his "designated spot" and ventures over to another gourami's "spot" they both wiggle their feelers at eachother and get a really dark blue color to them. Is this the norm? I think its really cool how fish show emotion or whatever with their colors! B)

i have a gold gourami who does the same type of thing. his color will change when he's tee'd off.
