It's time to add this wrasse to the 180. I figured I'd wait till at least close to lights out. However the fish is in sleep mode. I "think' it would be better to add the fish when it's awake than have to wake him up & add him at lights out. That means it's subject to the curiosity of a pair of clowns & 2 Butterfly's . Which would be more stressful ? Thank's !
