Someone is eating my sps

[Lorna]

I recently added a foxface to my tank along with a bicolor blenny. One of the two has been nipping and eating the polyps off my monti. digitata.......and my alveopora is not extending it's polyps and I believe it is being nipped at also......Not sure who the culprit is....has anyone ever experienced this behaviour with either of these two fish????

I have had a bicolor blenny and never knew it to nip corals (nor have I heard that they do); rabbitfish, on the other hand, I have no experience with but know from reading/talking to others they will nip at coral. I would bet on the foxface.

Could be either - both have form. You need to sit down and watch. My money is actually on the blenny.

The blenny is constantly sitting amongst the branches of the digi.....I haven't actually seen him nipping....he does a flyby bite and run when he does eat the algae on the back wall.....the foxface I have seen amongst the corals but I haven't actually seen him nipping anything.......though he always seems hungry and attacks the nori like crazy when I put it in the tank.....

blenny is most likely the culprit. I have heard them chewing on delicious polyps from sps branches.

hmmm I think you may be right.....though I haven't seen him doing it. There is not a lot of algae growing so maybe he is hungry?
