hard to say.

I don't think its redbugs...Im not sure if somethings trying to eat it or not...if so its at night!!Ill look closer tonight

now its 2 spots on it!! Ill take a 100mm macro shot tonight and see If I can get a better shot...

Its attached to the rock so hard to remove...I removed the colony because I thought it could have been flat worms and the frag grew back and done the same thing!

looks like a dead spot

Hendersonracing · #8 11/26/2007, 09:35 AM

but look at the polyps gret PE???what would cause a dead spot right in the middle of a healthy coral?

Hendersonracing · #9 11/26/2007, 09:36 AM

would that be were the stim has grown out and it takes a while for flesh to cover?

JRaquatics · #10 11/26/2007, 09:46 AM

Is it possible it is not getting enough flow?

johnnybravo234 · #11 11/26/2007, 09:59 AM

how about salt creep

Hendersonracing · #12 11/26/2007, 10:02 AM

its actually In a low flow area...If there is such a thing I have 4 6200 in a 210 modded.... so its like a title wave But I can put a 6045 in there pointed to it and see If that helps....I dont see any salt creep anywere so I doubt thats it?

...just a thought, maybe a crab or other pest.

A while back I noticed white/dead spots on some corals in the strangest spots (not the top or bottom, maybe a branch halfway up)...eventually I found a little jerk of a crab would come out when the lights were out, take a seat on the colony and then have a midnight snack.

I never lost anything...other than a crab that took a month to catch. The corals never seemed to be affected and always maintained good PE even after being nibbled on.

Of course it could be something else completely...

i know emerald crabs only eat a certain thing but mine took a chunk out of my superman. it looked like that. i found the chuunk on the sandbed. I stongly disagree that its redbugs. Its good to have everyones opinion thrown out and decide for yourself.

Is another coral stinging it?

An acro of mine was knocked onto an orange monti and stung it to death in the spots it touched it. Happened over night.

Hendersonracing · #16 11/26/2007, 02:19 PM

not anything even near it...Im thinking a midnight eater....I have 1 more Camel shrimp in my tank I was a fool and bought 3 but now have caught 2, 1 still in there....Im thinking he may be eating at night!

KurtsReef · #17 11/26/2007, 03:35 PM

I had seen a camel shrimp nipping at SPS polyps before getting rid of it, could be the culprit.

Hendersonracing · #18 11/26/2007, 03:36 PM

yeah but its very hard to catch in a 30" deep tank...in the wall...

rigleautomotive · #19 11/26/2007, 04:26 PM

it could be bacterial or fungal

knowcrap · #20 11/26/2007, 04:29 PM

Good luck catching that guy...I've heard those Camel shirmp are even more jerks than most crabs.

BTW - I get up early (so I can sit in traffic all morning) so wheen I was having the troubles, before leaving I would use a flashlight to scan the tank daily and kept supplies ready to catch or kill the crab...it was always out thumbing its nose at me but in the end with patience (and a sharp stick) I got it out of the tank.

Hendersonracing · #21 11/26/2007, 10:39 PM

Ill keep an eye on the coral tonight...I have the moonlights on...will they come out with them on????
