Goni not growing

[snk_anindya]

Guys,
I acquired couple of gonis few months back. In the past few months they have not grown at all. They dont even extend much. I've tried to keep them in various locations in the tank to get different light and flow. Nothing has helped.
Following are few details about my tank. Any suggestions appreciated.

Kh: 8.5
Ca: 410
No3: 5-7
Po4: 0.1

Mixed reef.
12 hours light including ramp up and down.
Reef energy ab+ dosing.

you parameters seem to be very good for gonis, maybe check your magnesium

its also worth noting that gonis are heavy consumers of manganese I would look into dosing it as it can really help with extension/growth and overall health

Goni's grow very slowly IME, and they often take a long while to acclimate to new tanks.

Personally I would raise yours into more light and flow, all the polyps are facing up, to me it kind of looks like there is no flow. IMO they like more light and flow than zoa's do.

Been going through the same thing, have had mine for 8 months they really haven't done anything and look similar to yours. Was watching a video on Parkers reef and the guy literally had wall to wall gonis in a tank, he said the secret sauce is consistently dosing manganese if your other parameters are in check. So I've bought Captiv8 Mn and diluted it and put it on a dosing pump we'll see only has been a few days so far.

found video Goni's and 43 minute mark

How long is a few months? No growth for a month or two is pretty normal as it acclimates, even if healthy. Beyond that, have you had an icp? Manganese is supposed to be important for them (at least some species).

Probably more importantly, do you feed any particulate foods? While not every particle size is good and not every goni needs it, it's been known for a while that a bunch of them really prefer to be fed with fine particulate foods - there are even some products made specifically to target this.
