I need to know if any of you have encountered this:
Yesterday, I changed light fixtures. I had a 48" 6 bulb t5 fixture on it, and upgraded to a 72" fixture with three 250W MH bulbs, four PC's, and 4 moonlight LED's. I realize I don't want to shock my corals, so I didn't immediately fire up all the MH's and PC's. I started up with just the two 250W MH's on the side, leaving the center one off, since most of my corals are in the center (due to previously having a 4ft light on a 6ft tank).
I don't recall seeing my Red Coris Wrasse immediately before putting on the new light, but I am pretty sure I saw him earlier that morning. I put the light on, with only the two MH's running. The overall brightness is about the same as it was with the six t5's.
Anyway, it's been more than 24hrs and I have not yet seen my wrasse out yet. It is possible that I spooked him when I walked up and began removing the old light. He spooks when I walk up to feed the fish, but will usually come back out when the other fish start feeding. Whether he went into hiding before I began swapping lights or if it was at that time, I don't know.... but I haven't seen him at all since.
Would changing the light scare him so much that it may take him this long to come back out? Maybe he comes out of hiding and the shimmering of the MH's scares him back into the sand? I have a lot of live rock. It is stacked up and covers about 2/3 of the bottom of the tank and slopes all the way up to the rear top of the 125g's. Theres a ton of hiding places, but I am a bit worried about my wrasse.
