Hi,
I sure hope he changes. His home is a 135 gal with a buddy that is a pinktail trigger. They are buds. Imperator is Shrek, Pinktail is Shad.
Get fed Angel formula, fresh shrimp, mysis, fresh clam, krill, etc., soaked in Zoe or Selcon, occasional garlic, have access to various sea plants, macro algae, live rock, sponge, hiding places, water movement (Iwaki 55 return), 80 gal refugium fed to main tank full of tons of life, just in case he needs that.
Keeping my fingers crossed for a change someday.
Definately post if it happens.
Sandy
