green acro?
 

I woke up this morning to something I've never ever seen or heard of. One of my acro crabs had moved homes, and is now hanging out with my other acro crab on its home. So I have two acro crabs on one peice of acro, this is the strange part.

The strange part is that between last night at midnight this peice of acro looked its normal brown with violet/purple tips, this morning is green! What the? I think someone should tell it St. Patty's day has past...

Anyways anyone ever seen this? What do I do? Frag?

thanks Muck! you rock...


Any ideas on whats happening?

Parameters are all good in my tank, Ca is a bit low at 420ppm but thats okay everything else is looking good.

Does the green area still look alive? (still have tissue on it..)
Its hard to tell from the pic. :confused:

It looks like it, but at the same time it looks like the brown tissue and violet tips (which aren't violet today) pealed away. It almost seems like the brown tissue was the top layer and the green was the underneeth layer just prior to the skeleton.

I'm starting to think this second acro crab, the top one in the picture, is to blame. I'm trying to find out if he is actually an acro crab or just some snotty little wannabe who's causing damage to my corals.

I think that the green part is dead skeleton. That's just IMO though from looking at the picture.

Thats what I was thinking as well. :frown:
Im not sure if the crab is to blame or not, though.
You don't happen to have a pic of the little guy do you? maybe someone can tell you if its a good or bad type to have... :confused:

I can't get a decent picture.

The one that was pre-existing on the acro is smooth and his claws are a light peachy color. The new roommate is kiind of fuzzy with bright blue eyes (like the light blue in the reef crew ad).

Grrr, fragging my 2nd favorite coral was not on my to-do list for my day off...

Alright I guess I shall be making mini acro frags AGAIN! Think I should keep the base and see if it grows?
That other acro I had who had a bad run-in with a powerhead, is base is regrowing, slowly and awkwardly, but it is regrowing. So what do you think?

Frag? Keep or not keep the base?

I would frag and keep only the larger parts with tissue on them. If the acro lost all of that tissue overnight, then something is wrong and it could just keep spreading and lose the rest of the tissue.

Well you are right about the spreading, between those first pictures and about 2 minutes ago there is probably only 10% of its tissue left. I just fragged what I could and damn is it sad...

The pictures of the new frags look very green, but thats not the case in real life...http://www.canreef.com/photopost/sho...php?photo=2471 And yet again I can't acutally post the image in thread...sorry I am going to learn how today...

How did you do it Muck? Help me!

sent you a pm.

Mr. Fugly
 

Got that second acro crab off of whats left of my acro frag. He's so creepy his name is now Mr. Fugly.

Is he an acro crab?http://www.canreef.com/photopost/dat...71PICT0014.JPG

Catherine,

Edit your post and delete the "?1684" off the end of the picture url.

I got it corrected in a new ID post...I figured it all out, its like html but with buttons!

Thanks though

:cool:

New frags didn't make it, their brown color has also since peeled off.

At least I can now say I have one of those green frags I've been eyeing all the time at AI! I think I'm going to miss their bright violet tips!

:frown: :sad: :confused: :sad:

Sorry... :frown:

sorry but i think the whole corals a goner.. the green frags looked like they have no tissue left.. just turned green due to aglae ..

I don't think its algea, I've turkey bastered it and nothing happens as far as color changes go. I don't think its algea

It is a type of algae similar to the hard green spots of algae you get on your tank glass from time to time.

I'm wondering if it really is algae. You didn't mention that the tissue was dying over a few days if I read the post right. It sounds like the tissue died overnight so algae wouldn't have grown so fast. It's not coraline algae so I'm wondering what's going on. I'd send a PM to Wendell or Jack.

Doug

Its not algea, it doesn't feel like it, it doesn't blow off my acro if basted by the turkey baster or slighhtly scratched by my nails

Looks like RTN to me, did you have any major swings in the tank or in the bag on the way home from the store. SPS are rated a harder to keep coral not only because of there lighting and Calcium demands, but also because they do not tolerate shifts in water parameters too well. A Temp., Sal., PH, Ca, or Alk swing could have caused this coral to die, not to mention a change in lighting or water flow could have too.

Rich I agree a rapid change in parameters may have been the culprit but that still doesn't explain the tissue loss and green colour just overnight. That is unusual. To the best of my limited knowledge of Acropora the skeleton should be white not green.

Doug

We have had that acro for almost a month and tank perameters were the same in the morning as they were the night before....temp was the same aswell!!!

You mounted dead acropora, sorry.

And that acro crab is harmful. Might of been the culprit.

How is it dead it's green??

All acros have a differnt colored skeleton than thier outer tissue. Rarely is this skeleton naturally white. The type of death that occures will determine weather you will see the actual color of the skeleton before it bleaches. In other words some die from the inside out and others from the outside in. I've had dead acros in my tank that didn't bleach for a week or so so I thought they were still alive until I finally examined them closely.
