I have been (successfully?) keeping a Goniopora Stokesi for over 6 months now. It’s finally started to grow a little, and reclaim some of its lost skeleton. I got it as a complete amateur, didn’t know what I was looking at but thought it looked cool in the store. In hindsight, I was getting what I thought was a great deal because the store rightfully assumed it was dying (clear evidence of tissue loss around its base). Today, that trend has turned around and it looks better than ever. However, 6 months is apparently the point at which most of these corals have a ticking time bomb go off and will suddenly die...understandably I am somewhat apprehensive about that.


Care habits:

I feed my tank often, at least twice a day. I start with Phyto Feast in the early afternoon, then later feed Oyster Feast and then sometimes reef roids as well (about every 3rd day for the roids). I don’t feed the full recommended dose for the Reef Nutrition products, rather I am trying to keep a small amount of food in the water throughout most of the day. I am also consistent with my water changes. I have a 28g tank that I change 5g every 10-14 days, in 2 different smaller changes so as to maximize nutrient export while minimizing parameter swings.

Equipment and Parameters:

i have a 28g Jbj all in one with the old metal halide fixture. I don’t run a skimmer. In the media chambers I have a small filter floss sponge that I frequently clean, followed by a bag of Purigen and a bag of Phosguard (not sure I still need the phosguard). I also have a bag of Matrix biomedia, as well as the bio spheres that I have crammed in every where. (I think I have 10 of those). I use a fan to keep things cool, and use an ATO to keep my salinity as stable as possible. I also have a bag of carbon just sitting in the back, my Kenya Leather Tree is now more of a Kenya leather forest, and the tank seemed noticeably happier after adding carbon.

due to the frequent water changes and feedings, the only parameter I worry about/dose for is Alkalinity, I keep mine between 7.5-8.0. My PH hovers around 8, salinity is 1.025, calc is perpetually on the low end, 410-420. (I don’t dose calc, just keep up with water changes. My thinking is that it is just something else that would upset the Goni). I also dose Fuel, which it seems to love.

Would love some feedback from anyone who has successfully kept one of these in the past!

Parameters look acceptable. What is the light you are using and more importantly, nutrient levels? Where these corals are found/collected, generally are high in nutrients with lots of food in the water column to feast on. Also, the flow should be on the lower end as well as lighting.

it’s a 150w metal halide. i have a 14k blue tinted Phoenix bulb in there right now. i 100% agree with low flow, it likes a gentle random kiss. I have the 2 returns being broken up by the rock and no wave maker to get what I’ve found makes it most happy, and feed 2-3x a day plus 2 fish feedings. I don’t run a skimmer, and don’t plan to as long as I’ve still got the Goni. As far as nutrient levels, I can’t detect them with my API test kit, but a little bit of algae will grow so I know there’s something there. Haven’t had issues with cyano or diatoms since it finished cycling.

That is a relatively high amount of light for that particular coral based on where I see it placed. It may do better at the bottom but it does look as though it is doing well where it's at. Being at the bottom might also balance the look of the tank as well. I'd move the Zoas and place it there and see what happens.

If I could move it down 3” I would, but the flow in the bottom corner isn’t random at all, it’s mostly just from one direction all the time. Where it’s at the flow kinda swirls up from underneath it, I don’t think it could get any better than that. I do wish it had about 50 less PAR though...another factor is my sand. I have a really fine grain, which looks great all smooth and white, not sure how the Goni would like dealing with that. Here’s an old shot from April 26th, right before I put it in the tank. That spot in the front just seemed so perfect for something with big wavy tentacles (my original plan was a torch). Also please excuse the really ugly tank! I still had a pure white bulb and at the time my temp was way too hot thanks to a faulty thermometer...honestly I have no idea how I didn’t lose a coral or fish.

Regardless of what anyone tells you, if where you have it, it's happy, leave it be.

Nice goni BTW!
Thanks! Interestingly, going back and looking at old pictures, the tentacles used to be thicker and longer, but less of them. Now, way more tentacles, but slightly shorter and thinner. It’s got to be a flow/light thing, but not sure if it’s good, bad, or just adapted to its new environment.

Like I said, it does appear to be doing well where it's at. Long term survivability and health of all our animals is a top priority. Goni's are notoriously difficult to maintain and have thrive long term in an enclosed system. With that in mind, we should always do what is best for the animal. I'm sure that the length and thickness of the polyp stalks are a direct result of flow and possibly other factors. Just be prepared to make changes as the needs of the coral indicate the necessity to do so.

It’s come such a long way, definitely been a roller coaster ride with this coral! I almost killed it with a salinity swing a few months ago (for comparison, every other coral was fine after 2 days, the Goni didn’t come out again fully for weeks) and it took forever to bounce all the way back and start growing again. I honestly don’t understand how something so sensitive evolved in the wild. The plus side is that it’s such a great barometer for my tank, it lets me know about EVERYTHING... which means if it’s happy, the tank is happy :)

Did your Goni make it? If so, how’s it doing?
