A fellow reefer had an ecrusting Hydnophora in his tank that sat about 6 inches below the surface. When he had his actinic lighting turned on, the hydno displayed a fluorescent bright neon green that looked beautiful. When his metal halides were on, it also had some very beautiful neon green coloration to it.
I finally talked him into selling it to me but as always (and like everybody else's story) it does not look anything like it looked at when he had it. I understand that the lighting has alot to do with it but I am not sure that is my problem as the neon green is there.
What I do not understand is why my hydnophora has extensive polyp expansion covering is beautiful green. When it was with the other owner, i never saw these polyps extended at all and as a matter of fact they looked like bumps.
My question related to the polyp expansion in my scenario. I run 3 250W 10K XM SE Metal Halides that are about 9 months old. The corals was also placed at about 6 in from the surface. My water parameter are normal. Is the polyp expansion due to lighting deficiancy requiring replacement? Is it possible that my water may have an irregularity? I also have a large beautiful rainbow monti that is growing very rapidly but does not look like the reefer a got from because the polyps are fully expanded hiding the colors. I am wondering if they are being deprived of something. Maybe the other refers were doing something wrong which is why they may have had polyp contraction.
Any advise will be appreciated.
