Hi All! About 10 days ago I put a Ruby Long Fin Fairy, a Lubbock's Fairy, and a Carpenters Flasher Wrasse, along with a Royal Gramma into my 50 gal reef. The next day, the two Fairy Wrasses and the Royal Gramma were no where to be seen. The Flasher Wrasse was swimming around for about 3 days, then it disappeared as well. The others in the tank are a Purple Tang, Coral Beauty Angel, Ocellaris Clown, and a couple Pajama Cardinals. Is it common for new wrasses to go and hide in the rocks when new to a tank? I know that the Royal Gramma that went into a mini reef I have would only occasionally come out when fed for a number of months, so I'm hoping the same applies to the new one in the 50 gal. Thanks for any input.
