which purple and yellow fish?

I'll tell you that my Bicolor Psydo was nasty mean.. He kind just hung out in the rocks but would go after almost anything that came near his turf.. The only fish that got away with it was my Naso and my Hippo both large fish. While I liked it I said I would not get another.. Not sure if the Royal is more peaceful or not.

 

If you have a yellow tang then you definately do not want a purple tang! Same body type and they will tear each other to pieces....actually the purple tang will demolish your yellow tang!

Somebody mentioned bicolor blenny! I absolutely LOVED mine! THey have a ton of personallity and are hysterical to watch. I had to get rid of mine because it became a clam nipper! THey live in holes throughout your tank and change homes often! They dont care what or who is living there when they take up residence. I watched my bicolor toss a crab across the tank cause it got close to its den! However Benny's last hole was right next to a clam...so everytime it opened Benny took a nip at it! So off to another tank he went!
