I recently bought a Lubbocks Fairy Wrasse that has some of the best coloration that I've ever seen in person. This fish was only about 2" long but displayed yellow, orange, red, blue, purple... Got him for $16.99 and thought I had nothing to lose. I've not had great experiences with Wrasse in my tank before. Most have died very early on for unknown reasons, so I had reason for my doubts. Regardless, I thought this fish looked awesome so I bought him. Put him in the tank and he disappeared. Ok, first thought is that he's shy. Give him a day and he'll chill out. Few days later, still no sign. Few days later, still no sign. Flashlight out, digging through the sand, checking late at night, early in the morning, feeding extra and watching the corners of the tank, etc..... Finally, tonight NINE days later, he comes out to eat. He hid, quite effectively, for NINE freaking days. I chalked him up to clean up crew food. He's out and about and eating like a pig, which makes sense if he's been limited to food for over a week. People said they've had wrasse hide for extended periods of time, I never believed it. Just an observation I thought I'd share.
