problem w/ hammer

[limitedslip]

I have a 20 gallon long w/ 2x65 watt PC. I ran into a problem, it does not like the lighting, I move it to my FOWLR w. MH main which is running a lower watts per gallon than my reef. but for some reason, it doesnt like my 20, and prefers the FOWLR, and its the only coral my angel doent pick at....which is wierd. Is there any reason it is not doing well in my reef? all the rest of my corals are doing fine...

Where did you have it placed and what kind of flow ya got? Generally hammmers prefer upper half close to the lights and moderate flow from my understanding.

hammer was in the exact of the 20 gallon (height and width) w/ a small powerhead moving at a mid flow at it, in my 125...its close to the bottom, w/ no flow...
