First fish and still doing great. He's my avatar when I had artificial pieces. Switched him over to the reef tank and had no issues. Loves his cave but will show and flash when I put my hand in front to defend his spot. Comes out plenty in the evenings and mornings (especially in the morning for feeding time). I stay away from shrimp, but I have wrasses as well so not much to do there. Overall great personality and addition to a reef tank.
