what is eating my leather coral! I took this picture at night so its easier to see the holes. Its opening up good during day.

i think it might be flatworm or nudibranchs. have you had a look at your tank at night? you might be able to see what is doing the damage then.

there is also a type of snail that will eat corals, rapa snail.

How long have you had the coral? any new rock added recently? what lights do you use?

Almost a year. Yes it started when I upgrade from a 60g to a 120g. Added couple rocks.

i would be tempted to dip the bit rock its latched onto and see if anything comes out. it really looks like its being eaten and not pulling itself apart

I wouldnt be able to dip the rocks. They are huge and there are a least 10 frags of sps's glued to them. I will look tonight. I hope I can see something

Using a normal flashlight. Why red?

 

[Zoey]

Because things that live under the sea can't see red, when you go in with a flashlight you'll scare everything away. I just use a old red bike light, works fine!
