Goin' LED finally

Try cutting the lights down by like 1/2 for a couple days and see if that changes the anthias behavior. They are darker/dimmer liking fish and do have a hard time adjusting to aquarium life because of that. How long have you had them? Are they still eating? How bright are the new leds compared to the old t5s?

 

Ohh definitely. ..I would cut back to at least 50/50 if not less and then bring it up slow over a few weeks. You can shock/burn corals with anything more than that and I would assume to believe that the light sensitive anthias are reacting the same way.

 

What kind of light schedule did you run with your t5's? I would try to run about the same amount of time (hrs per day) and then just start low intensity and work up from there. Keep your lunar cycle in place as that's a neat feature of running LEDs and its nice to replicate that real world event. I'm surprised your antias are being so sensitive to the change but I'd be worried about your corals just as much. It's SO easy to bleach them with LEDs.

 

Ive been a halide guy since i started, i just set up a 75 rr and decided to go with the kessil ap700, couldnt be happier with the look, programming options and user friendlyness of this light

 

So you ran 10 hrs a day with t5's and now with the LEDs they are on for about 18 hrs. Granted several hours are lower intensity but there is still plenty of light being emitted. I would try to set them to a similar time schedule as what you had before with the t5's and see if this calms the fish. Maybe take the intensity of the lunar cycle down to just a few percent also, peak at 4% instead of 8%
