I have had my LTA for about a week now and he is fairly bleached. He has turned to a translucent green color with white tips. Base is solid orange. The reason I think he is having problems with the light is due to the fact that he shrinks in size considerably when the halides are on, but is full size and healthy looking when they are off. He has taken two half pieces of silversides so far. How long does this acclimation to light usually take? Oh, by the way there are 2 250 watt halides, 20k. He is moving around the tank slightly. Maybe a couple of inches per night. Thanks for any input.
