that was me that suggested you try rearanging the rock...and believe me it works, I got my own clown to host this way and others have had success this way to....for all the nay sayers who think netting a clown once in a while stresses it out way too much, mine has been netted a good 20 times or more and is as healthy and feisty as ever, going on 3 years I have had him...not to mention catching the clown should be easy if you take the rock out and put it in buckets of saltwater while you rearange the rock, without rock in the tank catching almost any fish is a breeze... for you and them
