Oh yeah! My Aro's were very rhodophobic. I tried a Bloodred Parrot youngster and whenever I forgot and wore red, eeee gads, three lap headbanger session. I agree-absolutely terrified of red.
Mine used to be terrified of my hair too-if I would leave it down near the tank, Aro freakout. One time a chunk of my hair fell foreward into the tank and my Aro literally swam over, grabbed a mouthful and bit on hard and we played tug of war, darn it, gave me a mini haircut. After enough time though, he got used to long blonde hair but never red.
