Hello everyone, s
I've got a large piece of pipe organ that looks like its slowly dying. Over the past two weeks its been slowly losing polyps. Everything else in the tank looks great. Any idea's on what the problem is?
I assumed that you meant that you had just added it to your tank about 2 weeks ago. If you had extremely powerful lighting, it would be common for many corals not to behave properly and possibly die if not given enough time to get used to the lighting.
I've had mine under halides, T5's and PC's but I always started them off in areas that weren't as intense but that's common practice for me with many corals that I would have put in my DT.
I asked if it was an SPS dominant tank because maybe it was over the top flow and maybe the water was simply to clean as opposed to an LPS/softy setup.
If it's been in there for 2 years than I'd look at what has changed if anything at all.
Have you changed your lights?
Upgraded your skimmer or added any other equipment?
Increased flow in your tank to the point that it is just getting pretty heavy direct flow as opposed to indirect flow?
Did you add a coral or did a coral grow that is close enough to it that may be stinging it?
Did a clown recently start hosting it and it doesn't like being hosted?
How often do you feed your fish and is it enough? Maybe you have a fish that has taken a liking to it and you may be able to keep that behavior at bay if it isn't so hungry; just throwing ideas out there.
If nothing has changed and parameters are in check than like everyone else suggested, look for the pest/fish that is the culprit.
There are so many variables with corals like this, there isn't always one right answer. Many species of corals fit the bill for doing well in a wide array of conditions. Acans can live in low to extremely high lighting for example. Frogspawn can thrive in low to moderate flow and someitmes even a little bit higher. Some zoos can live in SPS tanks and some can't and some feel that the water is someteimes too prestine. Some can keep common euphyllia but not the more colorful variants.
=================================
Out of curiosity, of the people that have been keeping it successfully, are they in mixed reef (SPS, softy/LPS), SPS dominant or LPS/softy setups?
