micro/acan instant death

I have experienced the same problem and have lost nice frags, even after TMPCC dips. I have had two acan lord and two echinata frags dissolve away. The echinatas had been in the tank for 6 months and all of a sudden went down hill. One of the lord frags was 180 bucks. I looked at some of the tissue under a microscope and there were definately some type of tiny creatures that could not be seen by the naked eye, moving around in the dead tissue and eating it. I'm not the only one to have seen these things. Were they scavengers? Or were they killing it? I have no idea, but I'm sure they weren't helping it.

The best thing you can possibly do is try to keep your water as clean as possible and try not to damage the tissue at all, in order to prevent initial infections. Newly cut frags are at high risk IMO.

Besides this, I also had peppermint shrimp. I got rid of them and I'll never buy another one. They are extremely hard on coral and can be destructive if they sense food at all. I target fed one of my nices acans with shrimp one evening and in the morning, the whole center was torn out and it was white. Only on the polyp I fed. I'm positive the peppermint shrimp tore it up to get to the piece of shrimp. It's since grown back like new.

I also have a small RBTA that I fed. It ate the food. Food was gone. I came by later and found a peppermint shrimp with it's claws down the RBTA's throat ripping the food back out!! That was the final straw. They were even strong enough to rip food away from my serpent stars, right out of their mouths.

And the peppermint's can't be appeased either. You can give them a piece of food initially and it doesn't matter. If they find or sense more food, they will steal it. Which is why I won't keep them anymore.

Since getting rid of them, I haven't had any sudden polyp damage.
 
well, I'm pretty sure I've found the problem. There were some inaccuracies in testing the alk. I found the alk had actually been 6.1.. while my testing was 11.3. I had been dosing adv. calc to try to bring it down the whole time. :-/ I've brought my alk and calc back to 10.3 and 420 over the past couple days. I've seen some browning of my sps, but the remnants of the LPS seems to be fluffier. I believe a couple frags are too far gone to deal with the added stress of bringing the alk back up, but only time will tell.
 
I've never had any issues with mine, nor have any of my friends with them in the hobby. Niger's are common to reef, however, most tend to recommend them with caution.

i have the exact same thing happening to me only with the "popular fave" Scarlet Skunk Cleaner Shrimp. i hate it so much after watching what it does!
 
The only time I've had this happen was when I bought frags that were freshly cut, I think if mic's and acans are fragged they should be allowed to be in the same tank for 2-3 weeks and grow some then they will be really healthy. I divide mine up all the time and never lose any.
That's my 2¢ worth anyway.

Time to give an update. I've not found out why LPS don't like my 90, but after a couple of weeks no change for the better, and one night with more recession, I decided to set up a 29. I put about 20lbs of rock, some dry sand, and put a 250 12k reeflux over it and filled it with zoos, a chalice, a sps, micro colony, and 2 acan frags.. I didn't have the patience to wait for a cycle, so I added some stability. Wow, what a difference in temper with them all. The micros recession wasn't near as bad as I first thought.. it has really bounced back. I think this will be my zoo/lps tank and I'll leave the 90 with sps. Thanks for all the suggestions. Please keep me in mind if you hear something similar to my experience, as I would like to have the option in the 90: symptoms: growing chalice lacking color, and micro/acan recessions.
 
I just had the same thing happen to me. My sps are all fine, but lost several LPS, mostly chalices. The flesh was just peeling away. All Delight suggested I check my alk, which turned out to be very low, had been out of town for a while. Since I have been boosting it, everything is looking better. Had the shrimp and crab problem in the past too. What's next? :)
 
One of my colonies is starting to recede too, any updates?

I have an issue keeping my alk high and it sometimes dips down to 4-5 dkh until i raise it up. Just for a little background I'm dosing 9 oz each of randy's recipe #1 almost daily and keep my mag around 1350-1500. My tank is heavily stocked with sps also. Seems like a deficiency of some sort, maybe just low alk?
 
I know this is going to sound stupid, but I'm new to the hobby. Please explain what an Lps is so i can follow the conversations a little better. Thanks

Not at all.

LPS = Large Polyp Stony
SPS = Small Polyp Stony
Soft = no stones ;) like leathers and Xenia
Zoa = medium polyps, no stone skeletons

I think these are the major classifications of corals kept by us. Softies and Zoas are generally tolerant and good noob corals and LPS are pretty close to that also. We now have a frogspawn and more recently a plate and acan that are hopefully going to do well for us (all LPS corals.) SPS corals are generally more demanding so we're avoiding them for now. We also have some zoas and palys and two leathers.

If you spend enough time in these forums, this will start to make sense. I also see lots of questions posted in the wrong coral classification, so don't worry about being the only one who is unsure. You are not alone! ;)

If there is a good resource on this forum for coral classification, hopefully someone will point it out.

HTH,

LPS = Large Polyp Stoney corals
SPS = Small Polyp Stoney corals

there are lots of abbreviations on the boards, so if you have any more questions just ask.

Doh, not fast enough with my post! Stupid work always getting in the way!
 
kalk is just an additive to raise alk and calcium.. typically dripped or used in a reactor.

I no longer have problems keeping LPS. I don't know for certain what the solution was to my problem, but I believe it was due to nutrient poor with an extremely low PH. I raised my alk form 6.1 to 9.5 before ever testing PH. Several months later, I started the zeovit system and had to drop my alk down to 7.5. With my alk at this level, my PH was between 7.5-7.7, so I can only assume PH was much lower when my alk was at 6.1. I added a reactor full of large ARM media to buffer tank PH and calcium rx effluent and has since resulted in tank PH raised to 7.8-8.0 with alk at 7.5.

i hope this helped. :)
 
I believe I am starting to experience some of these problems with my acans. I have a post up now and I am going for some dip today.
 
i saw another post with similar symptoms posted here in the LPS forum. I believe people found parasites and were treating with interceptor. You may want to search around to find it. I believe title contained chalice and acan problems.. good luck with your situation.
