Help! Predator chomping on tips!

[Mike de Leon]

Something has been eating the soft tips of my acros. Started with the digis
. Then, my Palmers blue that really just started to grow. Now, the Tenius. I am suspecting some crab.

Here's my fish list. Will any of them touch sps?

Two Percs
4 anthias
2 chromis
1 yellow tang
1 serpent star

I only feed them once a day, and sparingly. Will this cause any of them to eat the corals?

Thanks in advance!

Any emerald crabs? Watch after lights out to see sps eatng crabs in action

You have a urchin?

gee I think every time I read a coral eating crab thread I find one in my tank! I had a frag that was STN'ing at the base for a few days so I decided to check it just after reading this post, low and behold, a crab munching at the base of it. This thing is TINY! be on the watch people!

A penny for size reference

I will try and look tonight. Very frustrating. The corals are just starting to grow!
