Who is eating my SPS?

[docs911]

Over the past three weeks, one of my fish has started eating my SPS. I have 3 Bartlett anthers, one blue tang, one yellow tang, one blue powder tang, one yellow and purple wrasse, one spotted mandarin, one purple mandarin, and two clowns. Which one could it be? I have spent hours watching them during the day and at night.

What is happening to the SPS that makes you think they are being eaten?

Tangs have been known to eat corals in captivity.

+1 but I never seen a tang eat/nip at sps...
lps I have seen them eat with my own eyes...

I have bite marks and chances out of my stylo and green slimer. I love the SPS. The wife loves the fish. I may lose this battle but I have a lot invested in both.

Could be AFEW- I would take it out that SPS piece and dip it in Coral-RX

Kinda hard to see but I had AFEW last year and was on my Acro they were small white spots

Take a look at this picture

AEFW don't eat stylos, AFAIK. If you sit and watch your fish, from afar, and never see any touch the coral, then I'd have to guess it's either a pest on the coral, or something coming out at night. Pics would really help

I literrally just put my red sea sailfin in my buddies 220. I watched him pick at 3 or 4 different colonies last night. I've had him for years without problem until this last week. He also loves bubble algae. Sad day around here... I would say that it's most likely your yellow tang maybe PBT.

It may be one of your blue tangs; mine eats the polyps of acros all the time...
