Goniopora

[Charlie brown]

Quick question my goni is not fully extending all parameters are good, no elevated levels in my tank mag cal nitrate phos alk all good everything else is growing and happy acros and Monties are doing good just noticed my goni no to happy all of a sudden? There is algea growing around the base of the frag but never really seemed to bother it before but that's the only thing I can think of why it's not extending. Have anyone of you guys ever dipped a goni in peroxide before. Is it even safe to do that with a goni?

Happy to help, but we need to know what all good is. Specific numbers will give us more information.
Goni can be finicky and don't seem to like changes in current and lighting. They also prefer some nutrients in the water. The fact your acros are thriving makes me think it may be too low nutrients or something like flow or irritation from a tank resident. Especially if the change was quick.

Exactly what does thriving acro's have to do with low nutrients?

I will agree that hard numbers, not just telling us "everything is good" will go along way in diagnosing your problem.

It's a guess based on the limited information we've been given . I figure acro happy, nutrient loving coral not, but could be many many things and not nutrients.

I have a couple dozen Acropora and probably a dozen and a half Goniopora in the same tank that are perfectly happy together. My boss has many many more than I do in our newer aquaculture system. At the store we had our mother colonies 6 inches under our Acropora colonies. All of that being said there are various species of Goniopora and I have seen a few bleach. In my opinion the notion that this coral or that coral like dirty water is just misinformation. Some coral won't react negativity to elevated levels of nutrients, that is true, but does the N03 of 50 or PO4 of .19 really help their growth. I would also not confuse nutrients with available food.

Like I said, it was a guess based on limited information... its hard to say what is bothering the goni for sure without more information. In the wild Goniopora inhabit turbid, nutrient rich water. That doesn't mean I don't think they can't coexist with the same parameters or require them (especially aquacultured)but absolutely some corals prefer environments that have higher bioloads and food.

Yeah, most people say Goni like dirty tanks. I think the reality is that Goniopora like access to food. I think a part of that is also that they like trace elements that some tanks may be lacking, such as the manganese that some folks talk about. Also there are big full blown SPS tanks that run much higher nutrients than the masses would say it's possible, look up some MACNA talk by Dr. Sanjay Joshi.

 

[Wasabiroot]

For sure. My acros seem pretty happy in nearly .2 phosphates. Hopefully we can help figure out what's wrong with the op's gonis.

If there isn't anything physically bothering it, check your nitrate. Some of my goni's tend to close up when nitrate gets below 5ppm, and then bounce back within a day or so when I get nitrate back above 5.
