What did this to my Chilli pepper?

[saltyhog]

Came home from work to find this on my chillipepper. It was pristine when I left for work this morning. The only thing new in the tank is a black combtooth blenny that came out of QT 2 days ago. Is he the one or is it something else?

Maybe salt creep being knocked into your tank? Detritus sitting stationary for a while? I don't think montipora eating nudibranchs but could be wrong. Any changes in parameters lately?

 

[saltyhog]

No changes in parameters Alk 8.3, Ca 450, Mg 1350, pH 8.3 Nitrate 5. They've been there for months. Now I found a similar mark on another frag .

Sure does look like something,g is picking at them. I would keep a close eye on the tank

I no longer keep blennys in any tank with SPS. He would be my first suspect...

I had a blenny at one time in the past. And yes theos are the markings of blennys mouth.

Looks like your blenny maybe the culprit here. I had a bi color who I always caught biting on my monti plates.
