I've had my ORA yellow Assessor for years now, and I love that little guy. Especially the beautiful colors that edge all the fins -- greens and oranges. It does go into the rock work all of the time, but I only have to be in front of the tank for 30 seconds before it is hanging right out in front, usually at some strange angle.
Almost all of my planktivores take in a lot of food and then spit a percentage of it out... I do not know if it is my food, or if it is a "thing" with planktivores.
That is a great price for ORA assessors. I might have to check out the petco every once in a while. I've wanted a Randalls for years now...
