so, to start, I've had this particular wrasse now for close to a year, was eating great, very active and didnt appear to be being harassed by any tank mates. It had come time for me to change the bulbs on my T5 fixture, and the day i changed the bulbs i had to turn off the lights in the middle of the day, which I've done plenty of times in the past BTW, and after chnaging the bulbs turned everything back on and wrasse had dove into the sand. I thought, "no big deal, he just got spooked and i'll see him tomorrow" and thought nothing of it. Well, It's now almost 3 weeks later, and he STILL hasnt come out. Not sure what to do at this point, I know you are never supposed to disturb them when they dive like this but i dont know how much longer it can go without starving to death. FWIW i do know it is still alive, I can see under my tank and know where it sleeps so i can actually see the wrasse and she is still twitching and moving around under the sand. Has anyone ever experienced this? It just seems crazy to me that an established wrasse would hide like this over just the changing of the bulbs.
