I got a new Angler and a Blue head Wrasse on Saturday. So i acclimated them and when it was time to let them go the angler hid behind some live rock and the wrasse VANISHED. This is my first time having a wrasse and i am not totally sure what to think. It is now Tuesday and i still havent seen him. Can a Blue Head burrow into substrate. I also have a lot of live rock in that tank. A few big peice with little caves but they dont look large enough for the wrasse to hide in. I have no clue where it went. It is about 3 - 4 inches long. i have about 4 - 5 inches of substrate. Does anyone know how i can get him out if he is hiding i have put mysis into the tank also ghost shrimp for the Angler. PLEASE HELP
