hi everyone! I have a tree sponge and gorgonia in my 54 corner that are giving me problems.....tree sponge i have had about 1 year and last couple of months I have noticed that the polyps won't open for feeding and is turning white! look my gorgonia won't open open either have had that for 3-4 months at first all the polyps opened and would feed well I have moved it around my tank several times hoping it would like a spot and open again1 I don't have experience with these two species and could really use some advice! i am being told to remove the sponge now to prevent toxins from being released? what do you think? are they dying? how do you know? I attached a couple pictures! thanks

Posting parameters is pretty much essential when asking these kinds of questions. I'm not being snarky, just trying to illustrate a point. What you posted is pretty much the same as posting
"I have a red geranium in my kitchen. Sometimes it looks good, but lately it hasn't looked so good. I moved it from near the window, over to near the sink. I've never had a red geranium before. What am I doing wrong?"
Lots of people read posts, see that there isn't enough information to even begin to answer, get sour and walk away. Some folks ask for parameters, and never return once they are posted.
Again, not being snarky, actually trying to help.
What size tank, how long has it been running, what lights are you running (they affect other things, so just because your posting in NPS doesn't make that not important), what is your ammonia, nitrate, nitrite? Calcium, Alk mg? How much and when do you feed, water change? RO/Di water/ What fish are in the tank? Diagnosis will be much easier with those things included. Truly hope that helps...

Yeah...guess i should have just viewed it and moved on like the other 50 people.
I've never done well with NPS, but my best results came when i had them in caves, shadowing them from direct light. Since the gorg is going to want lots of flow, doing so might be tough. Also, with such a low nutrient system it would be good to know what if anything you are using to target feed...
I realize thats not much for actionable information, so feel free to consider it nothing more than a free bump
