My firefish has always been an open water swimmer, he would find that niche between my two mountains of live rock and hang out there all day until feeding or bedtime.
The other day I noticed him sleeping in the corner of the tank when the lights went off. Normally he would sleep in the coral head.
Didn't think too much about it, but the next day I noticed some of my hermits had died.
Ok, check water, everything I tested was good. Performed my weekly water change the next day and retested. Everything where it has been since forever.
Then I see this small (1") hairy crab in my tank. I didn't remember inviting any crabs, but I had some newer live rock and figured he was a hitchhiker.
Is there any chance that this crab is the reason my hermits are dead and my firefish is missing? I picked out the rock I saw him on and dropped him in my water bucket. He didn't care for the light too much, so it was too hard to get a picture. Best image I can find says Mithrax, but not sure.
Any thoughts? Where would the body of the firefish be?
