Help please >,<

[Drewpdog]

so i woke up this morning and and half of one of my collonys is gone and i stared ar the tank for like 3 hours looking for any little thing i could see that could possibly be the culprit and all i could see was i saw like twice this TINY like worm crawling over the rock that used to have my zoas on it.

the worm:
White/clear
about 3 mm long
and less then 1 mm thick

thats about all i have to go on any ideas segjestions would be apreciated

If they were orange envys or PPE or Amagedons then a fellow RC reefer may have broke into your house and stolen them while you were sleeping.

Kiding asside, do you have any angels? did you add any new live rock? do you keep large hermits?

 

[Angela Short]

tangs have been known tomunch them also among many many other animals...

 

[Drewpdog]

my only fish are a chromis and a pair of black white percs

i have 2 hermits a very small zerbra and my halloween hermit isnt that large like his claws are 7mm long and 2mm wide

i lost 5-7 polips over night and where they where is clean just coraline

What is a halloween hermit?
That's the first thing I would suspect with the info given here.
A picture of the piece would help.
Also I would look for sundial snails. They'll take out a whole polyp overnight where a nudi will take longer usually.
They were all there yesterday, weren't they?

 

[Reef Junkie]

Bingo, you took the words out of my mouth mfinn!

Also, list your tanks parameters. If you're not sure, test now.

 

[Drewpdog]

yea all where there yesterday
the halloween hermit
very thin spindaly legs and claws with very very thin black and orange bands and his body is a white (saw him change shells once)
i cant do pics i left the charger for my digital camera in austrailia >.<
found a pic online

 

[mfinn]

Are they a type of hermit that gets big?

 

[ADesertReef]

Drewpdog, does the hermit look like what is in the picture or black and orange? I have a "halloween hermit crab" which is black and orange. It is a color variation of Calcinus elegans which originates from the Hawaiian Islands. Many may be familiar with the blue varient found in the Marshall Islands and vacinity which is commonly called the "electric blue".

 

[Drewpdog]

mine is black and orange i think the white is off on that picture

 

[mfinn]

I have seen in my own tanks over the years that the larger hermit crabs have a tendency to eat corals when the run out of other foods, even the electric blue hermit. Caught mine eating my neon green ricordea.

The worms are probably planaria ones. I have them and they don't eat zoas. They make zoas close (which is bad too I think) but they don't aet zoas.
