What coral just does not work for you?

[2Wheelsonly]

Torches and zoas. Torches because I always have high flow running mostly SPS; no idea why I can't keep the zoas.

I have been heavily involved in my reef tanks since 2008 and I have never ever been able to keep zoas alive other than colonies that came off live rock (I have one colony of ugly zoas going on 10 years).

Riccordia. They bleach then melt away over a few months. Really weird.

Everything else seems to do okay, not always perfect but alive at least.

I feel for you mate , zoa grow crazy in mine ....to the point of starting to get abit out of control , but I still add the odd frag lol some are just to colourful to leave in the LFS

Your not the only one.

Zoas and Candy Canes. My zoas seem to grow and extend, just rarely open lol. And my green candy cane coral will occassionally plump up, but no signs of growth whatsoever lol

Are you sure its not due to some sort of pest? Zoas get lots of pests including nudibranchs.

I don't know. I've dipped them several times but maybe I'm missing something. Is there anything in particular I should be looking for?

We all have that one coral that refuses to grow despite other corals doing well. For me its duncan corals, and certain zoas. My bam bam zoas grow just fine but my sunny d's not so much.

I've had an issue of growing zoas and duncans for the longest time, until this 12 year old kid came to see my tank and told me that zoas and duncans require a lot of flow. As soon as I raised my flow, literally over night things changed. Hope this helps. Sidenote, make sure sg is around 1.026, your mg is not too high and make sure to feed your fish daily and as much as they will eat without raising your po4. Zoas will usually melt if you have a lot of magnesium.

Blue SPS

Try testing and dosing potassium. This helped me a lot.

Try testing and dosing potassium. This helped me a lot.

Actually that was the first thing I did....potassium tested within range. Not sure what the issue is....just can't seem to hold the color blue at all. I have every color acro in my tank, except blue lol.

My sg is too high atm and Im getting down. Mg is high but im letting the corals consume it.

The moment I realized just how much I liked the Duncan I bought (husbands pick at LFS) it immeadiately started shrinking. I’m down two one head and it’s hanging on by a thread.

How are your nutrients?

I just checked your thread. Looks good. If your potassium is in check try feeding your fish more and increasing the flow. The reason I am saying to increase the flow is that your monties and your acro branches look a bit thin. Also it looks like your water level is too high for you to kick up some major waves, I have the same issue with my tank, to prevent the water from spilling over I would suggest lowering your pumps within the tank that way you won't get as many waves. As far as the feeding goes, your glass looks pristine, and you have a top-notch equipment. Corals need to be fed, they don't need to be smothered with no3 and po4 or it doesn't need to be detectable, but when you don't have any algae growing on your glass ever, that might be a sign of a system that could be starving. ( again these are jsut troubleshooting suggestions, you might have all of those things in check)

My sg is too high atm and I'm getting down. Mg is high but im letting the corals consume it.

Take out a few cups of water and add rodi instead to lower both the sg and MG. Corals don't consume a whole lot of magnesium fast. It's better to adjust that manually and see if you stop losing your more sensitive zoas. Hope this helps.

I can grow just about any color of Acropora, but the blues elude me.

 

[Gungo]

Gorgonians just don't survive in my tank...

 

[scsdukefan408]

For me it’s Chalice’s and Blasto’s. I have always had a mixed reef, but never able to keep those two happy for long

 

[Dragon52]

It seems like anything with a skeleton structure( Birdnest ETC) just will not survive more that a wk so I don't buy them anymore even though I really like them.

Toadstool leather would rather be closed then open for a good month now little sht

Any zoas, my blue spot puffer loves to munch on them

I'm not sure what melting is. They just start to thin out and eventually all of them are gone. It's more of a long slow process of deterioration.

Than from Tidal Gardens has a top 5 pests video out on the web. He described zooanthid eating spiders that lay eggs into the zoa mouth and when they hatch the polyp melts!!
