Things With Stings R Us!
the radiata went and bolted to the opposite end of the tank and looked VERY pale in coloration.
What you observed was the "stress coloration" of the radiata, which was brought on by the fish being spooked by its tankmates.
P. radiata is a good solid eater once conditioned and weaned, but they aren't super aggressive feeders, esp in the presence of a "mob" (they will usually just back away and let the others take all of the food). This is why it's best to get them conditioned and weaned before placing them in the DT.
Your best bet will be target feeding the fish if it will accept food from a stick.
