Who's Chomping on my Orange Stripe Prawn Goby?

[kylewest]

Hello,

I have a 120-gallon with the following fish:

* Orange Stripe Prawn Goby (Amblyeleotris randalli)
* 2x Ocellaris Clownfish
* Dilectis Dottyback (Pseudochromis dilectus)
* Black Combtooth Blenny (Ecsenius namiyei)

All the fish were added at the same time and are well fed.

This morning the goby has a chunk or two missing from his big dorsal fin (the one that looks like a fan). Other than that he looks fine and I don't see any battle scars on the other fish.

How do I figure out who did it and what, if anything, should I do about it?

Thanks,

Kyle

two fish could be possible suspects: the pseudo and blenny

If I had to say.It would be the Combtooth Blenny.There may be another predator in your tank your not seeing though, invert wise.

My vote is the pseudo. I had a springeri that LOVED to rip the dorsal fin "eye" off my randalli

I was guessing it was one of those too. Now, what to do? Just a skirmish or something I should be worried about and taking action?
