Biodiversity? I think not..

I believe they have been in the higher level of salinity since Aug 7th. That was the day I made the final addition. Two of them opened up for a couple of days, then promptly shut. I have not seen them open since. I took teen's advice and let them dry for about half an hour, and gave them a quick dip in fresh water. The only thing that I noticed were all the pods that were still on the rock released and were very unhappy. The zoas have still not opened. I haven't noticed that they are decreasing in number, in fact, I see some new little zoas growing. I just wish I knew why they wouldn't open. This is highly frustrating for me, and I wish there was some fix for it.

I read somewhere that the only way of knowing there is a health issue with zoas is if they do not open for long periods of time. (I think I've noticed that already.) However, there is no way of diagnosing a problem. The artcle also went on to say that if they start detaching and floating around, then you have a serious problem. It also recommended a 50% water change, which I did today. But I do water changes pretty regularly. We shall see if this water change does anything for them. I am going to head up to the LPS here this week, and see if the lady there can offer any advice. I may do the dry and dip again, and isolate them into a different tank, and see if they improve any. I'll keep you all updated!

Every one of my zoa colonies would close up for a period of time every so often. I was worried at first when it happened, but they would open up later looking better then ever. So I just stopped worrying about them. The spiny looking nudi you were talking about scares me a bit....You should watch out for zoo eating nudis!!!! I had to deal with'em a couple of times before, the first time I got rid of them quick, but the second time was pretty bad, took me over a month to rid all of them.... :happyfish

So that "spiny" nudi thing I had was a Zoa eater? Heck I thought it was pretty cool looking. I just assumed that after my lettuce nudi dissapeared, and this thing appeared that it was probably laid by the lettuce. Really I guess that's silly and all, but where else could it have come from, lol. I know I must have burried the lettuce during a cleaning, and I've never seeing it since. That spiny thing appeared a week or so after, I noticed that it spawed off of my fan plant, but it too has dissapeared. I had never seen it get anywhere near the Zoas, it just hung out on the glass and that fan plant. Anyhoo...

I dunno what it is until I see a picture of it. Start looking up photos of zoo eating nudis. :happyfish

IMHO, get some anemones. Your corals may be closing because they are eating those and are simply not hungry.

Eating what exactly? The pod bugs?
As an update, the Zoas have still not opened to this day, and I'm really wondering if I should give up on them, scrape em off, or just leave them be. I supposed I could get another order going for some more things, but I really would hate to get another Zoa rock, and have them do the same thing.

Did you ever check on those zoo eating nudis??? They will cause them to close up and eventually melt away.....A good iodine solution dip will help to rid those nudibranch. After dipping, best to place the colony under actinic lights for the rest of the day and back to normal schedule the next day. Actinics will encourage them to re-open. I had a colony that closed up on me for 2 weeks once. I accidently squirt them with Joe's Juice, but they did just fine afterwards. It looked rough when it first opened back up, but it then recover just fine. :happyfish
