My green acro has been doing ok however two or three days ago I saw one or two polyps without skin (I guess). Today three more :(
Do you think this looks like fish nipping? Or something else is wrong ?

thank you for helping.
 
What fish or inhabitants do you have in there that would nip anything? also what is your alkalinity at?

Live stock is:

Mimic surgeonfish
Palette surgeonfish
Golden wrasse
Blackspot angelfish
Pyramid Butterflyfish

Lysmata seticaudata
Cleaner shrimp
Diadema urchin
Astrea snails

My KH is 8.0
 
im not to sure if the fish will go after polpys but possibly the butterflyfish. watch it over night maybey, im not to sure it seems that the polpys are being eaten or the tissue is burning off and the polpys burned as well but if it was burning it happen from the tips or the base mainly. hopefully a fish expert can chime in.

sorry I just tested KH and the right value is 10.9 now after 1hr of lights off
 
huh what kind of test kit are you using? also can you track the kh to see what the swing is? usually when its alk burn it starts at the tippy top it looks like you had a old dead piece of the coral on the bottom left. did you dip the coral when you got it?

Im using the Salifert KH/Alk Test.

I did not dip the coral but I gave it a good look and did take a small white crab from it.

I had it under led light at first and it did bleach a bit. Changed to T5 lights about Two month ago and it was recovering prety well.
 
yeah its not alk other then i could think of would be flatworms maybey, give the sps in a revive dip before you put it in its painless and easy and very effective and check any spot thats not tissue for yellow eggs.
 
Looks to me like it is being nipped at
I also thought of that but I never saw the Pyramid Butterflyfish near it the only fishe that is always nipping the live rock and goes near it sometimes is the Blackspot angelfish but I never saw it touching any coral. I also thought of the Golden wrasse if the acro has any pest that I cant see.

Yes you are absolutely right I should have diped it. Instead I had it in my QT tank for two or three weeks but now I`m not shure that some kind of pest has not entered my tank.

You think a dip is any good now?
 
it looks like its being nipped, although the bottom part of the coral is dead the one spot im looking at looks like right on the poly hole there is no tissue, which means a crab shrimp fish pulled the tissue off. Dont get worried or anything i was just saying that because i saw a dead spot. if the dead spot had aefw then the eggs would survive a dip and thats mainly how they get into peoples tanks. A dip may be good now i think it disinfects the coral and also helps it to heal.

Yes I might give it a dip tomorrow. I only have Kent Tech-D or TMC coral cure available
 
i hear tropic marine is harsh on the coral but it gets the job done. revive and coral rx are very good and very forgiving on the coral.
