zoas

I have 6 different colonies of Zoas on one large rock. They've all been doing really well, but about two weeks ago one of them closed up and hasn't reopened. there are two polyps out of the whole bunch that are still consistantly opening. Any ideas what would cause this. i've searched and searched for signs of something eating them like Nudi's but I can't see anything. They're slowly shrinking and going away.

What up wit dat?

i have had this happen before, never found out what the problem was. probably some sort of disease.

this is one of those mysteries in coral care that i think still doesn't have an answer. you will find many posts from others with this same thing. i have lost zoas before but ususally if they are not going to make it they start out bad and go worse and i blaim that on S+H or not acclimating to the system, i don't think i've ever had a good zoa go bad, but it is unfortunitly common
my best GUESS on this situation is improper flow or light. we tend to place zoas all as one animal but they are not - some have very different preferences then others.
for example: i have a zoa - my pink sparkels - that is extreamly finicky. in the 125 they always did well but the few frags i have sold never seem to do well for others. and i couldn't even keep them in my frag tank - they would either brown out or worse - melt away. they are so touchy that they are the "indicator" in the new zoa nano i just set up - i check them closely everyday to see if i have to move them back
you could try moving them down or up but if the rest are happy and healthy you may just have to split it off from the rest. another thing is you could dip them. julian sprung has a product called REVIVE and i really like it. at first glance and reading the ingredients list you may think it is snake oil - but i have used it and believe it may be the best new product on the market for disenfecting corals. i have been using it for a month now and all my corals going out or coming in get dipped in it
good luck

Yeah, They've been in the tank at this location now for about 2-3 months and were doing great until they decided not to open. I'm going to look into that REVIVE stuff. So you say you can dip all your corals in it? SPS and everything?

I've glued the little piece they're attached to a larger rock. I guess I'll break it off and try a couple things. It's not a big deal, one of the more bland colored zoa frags I got for $5.

Thx for the tip on the new dip there John...Have to try that. You recommend it over lugols?

i would not say i recommend it over lugols as i use two dips; one is a mixure of tmpcc (basically lugols) and fwe - i have been using this for years and doubt i would add a coral to my tank without it, but now, i use the revive dip after that dip as a secondary. i do feel that it is very effective and does seem to be less stressful then other dips as even sensitive corals like montis tend to open right up after using it

I don't think it's too surprising at all...

Listen, just because some shmoe aquacultured two different zoas onto a rock doesn't mean they are compatible, even close to being the same (even though the may look like it at first glance), heck they may even be from seperate parts of the planet.

It could be some type of allelopathy, but my guess is that is less than likely, as they have coexisted for an extended period until now.

Probably a minor change in temperature, gravity, or any water parameter that one is sensitive to, but not both. And, unless you do regular testing and charting of that information, you will probably never know!

Nooooooooo did I misread? If you were the one who grew them on this rock then I totally apologize. I was assuming you got them that way from another source.

Maybe we should switch avatars.
