My purple is a complete ******, in a 315 gallon you would think he would be fine with the yellow, but boy 6-7 years on he still can't stand the yellow. Especially if he feels food starts to get scarce aka I don't feed as much every day. So, I am going to catch him at night and put him in my 50 gallon rubbermaid sump (corals and cuc in there). Any chance he hops out while in detention?
