Was it a brown jelly slime?

 

[grisha]

It was very light, looking like a slime after coral been attacked by something stronger. But nothing could of attacked it. It surrounded by acans

Damaged polyp trying to expand and feed. No jelly or slime accumulation
I don’t think anything like fish or shrimp can attack it.
I have a cleaner shrimp, blood shrimp flame hawk clown and Midas blenny. Hermits pretty rough bunch but they keep to fight between each other
Measured all 6.5 gonna get it to 8 next 5 days

If I'm seeing it correctly, something ripped some chunks off of it. Other blennies can eat corals, is there a chance yours has been?

 

[grisha]

Acro, thank you for input.
My Midas blenny is very docile
Hawk is a boss but should be reed safe
Clown, no way
Cleaner shrimp or blood shrimp just don’t have that power
Hitchhiker? I don’t know, I buy frags, but I don’t think anything could pass my dips
Only one coral affected, it’s 95% Acan frag tank. Over 100. It did had a slime on it, but I always though jelly is fast and you can almost see it grow within an hour time span and can half of affected polyp try to live after it slime ?

 

[grisha]

i consider that acan the Annabelle of coral because it looks like Satan himself has manifested into it...

Let it be satan, just not jelly

I had a clear shrimp eat acans before. I had to remove them.

I would not passively stand-by and move the frag to a different spot.

Wow, he just molted last night

Kind of though of the same thing, but in the other hand, change of flow/light might irritate and cause more weakening? This way I wouldn’t know if that killed it?

lights out shot
8 hour later. No slime accumulation.

Third day update
2 polyps that were immediately affected in first picture continued to deteriorate
There is a brown slime
My question. If this a brown jelly desis e can it be moving so slowly? Quotes of polyp a day?
