Japanese Zoanthids?

[jimsflies]

Curious how everyone's japanese zoas are doing?

I'm concerned that if these zoas are really from Japan and from deeper water as some vendors have marketed, that they may not be suited for a tank with higher lighting and warmer temperatures.

I have a couple frags of them and they are starting to show signs of problems on a few of the polyps. The polyps with problems are becoming thin at the base and are developing that brown fungus look to the polyp...perhaps even looking a little zoa pox like. I also notice some tissue or perhaps it could be a sponge coming loose between some of the polyps. I started dipping mine in Furan 2 and also soaking in tank water with iodine. That seems to be helping, but I'm not sure if the battle can be won or not.

hmmmm... interesting... I'd also like to know how everyone's Japanese or Deepwater zoas are doing?

 

[I-K@ndY]

I only have 1 morph and so far its not melting yet

 

[Fish n' Frags]

Ours are doing great under 250W Radiums and in our T5 tank. Frags and colonies..... so far

 

[pakora]

mine are also fine, but ive only had them a few days LOL

Steve, nothing dies in your tank. haha Steve's tank is like the "fountain of youth", everything looks so much healthier in it. You got any pics to post? Thanks for sharing. Al

 

[jimsflies]

I guess the other part of the question is how long have you guys had them?

I spoke with a vendor this afternoon that lost $2000 (wholesale) worth of them over the course of the week in their systems. Mine did not come from this vendor but I have noticed similar symptoms developing on mine.

 

[Viva'sReef]

Yup Jim, I totally lost my 2 frags a couple days ago, my third frag seems to be unaffected. I had them in my tank for about 3 weeks, then the beggining of this week they started acting up, not opening, getting the brown fungus on them, and then fully melting a couple days ago. I had them near all my other zoas, and they are all unaffected by this. Its also worth mentioning that they were shaded, and on the sand bed of a 24" tall tank

i had one that didn't open for a few weeks. I did an iodine dip, and it had a fungus type growth as well. after the dip it appears to be back to normal.

A lot of the fungus you are seeing is due in part because the way they were shipped and they have arrived infected and the importers did not know how to treat them. Several shipments from one of our vendors were infected and he learned real quick about dipping and quarantine. My last shipment was flawless. I havent lost one polyp and have not seen any apperant problems. They were quarantined prior to my arrival and then I dipped them for 15 minutes in Tropic Marin pro cure. I have held the shipment in my tanks to see how they would fair prior to selling any and they are all looking eye popping and problem free.

You might also want to consider temperature. If they are in fact coming from deep water they may need lower temps to maintain them long term. Just a thought.. The corals that I have got from Japan in the past did much better at lower temps.

[jimsflies]

Yeah, the temperature concerns me. I don't see lowering my tank temp and keeping everything else happy. Summer will be a problem anyway.

 

[oceaninabox]

My tanks temp is 72-74 and they are "THRIVING"..

 

[kev2me]

My tanks temp is 72-74 and they are "THRIVING"..

Sweet, they should do very well in our tank once we get some.

 

[flricordia]

I have been keeping the ones for the grow out under 14k Phoenix MH about 10-12 inches under and temps at 80F and they are looking awesome. Guess it has been over a month now? They are starting to put out little ones too.

Get some Kent's Iodide and place them in a straight solution for 45-60 seconds, shake off the excess and place them back in the tank. Should help them. You can also add a drop of flatworm exit in case there is a zoa nudi or something else bothering them.

 

[robharold]

Man I just got a frag. Hope they don't have any issues. that would suck b/c they were not cheap.

 

[Tomasz]

When they were first shipped they were shipped in a flos and ice packs. By the time they arived here the water was ice cold. I think the supplier has changed how he ships them now and they should be doing much better. I have some from 2+ months ago that do very well and once they start to grow they are good growers:bigsmile:.

 

[ZOABOY]

I would like to own some in the future.

Thomasz, have you or others been able to verify that they in fact come from Japan? Theres a guy in my local forum giving a girl a really hard time saying she got suckered into the latest trend and that her zoas prob. came from the Solomons. Id really like to know the story behind these...

Im not trying to stir up trouble, just trying to become informed on the deal with these things... TIA....
