I bought a multi-color angel on 2/8. Right out of the bag it swam around the tank and ate. On 2/13 I cleaned the lens on my pc lights . I have 260 watts of pc lighting on the tank. Now it stays behind the rocks and will not come out into the open. When I feed, it eats what the current takes behind the rockwork. I can get good looks at it and see no signs of anything physically wrong. I am curious if the intensity of the lights has scared it into the subdued light behind the rockwork? I know the tank inhabitants are not harassing it. I also know the multi-color angel is a deep water fish. Any suggestions would be appreciated.
