Just curious. I have a red head Solon Fairy Wrasse which has failed to show up the last couple of days. I've checked the overflows and didn't see him there. He's usually out but he has disappeared for a day every once in awhile my guess is he's not coming back at this point. I have a tank with a lotta Rock so generally speaking if one fish disappears I don't go digging around trying to find it. What do you do?
