Some thing Attacking my Chromis

Hello

i have had a Blue/Green Chromis in my tank for over a month now (1 fish only and the only fish in the tank) and the last few days i have noticed it looked spooked, now today when feeding i have been able to get a look at one side of the fish which has clearly been attacked it looks like it has been speared near the end of the tail and it has be lacerated near its front fin,

the only other critters in my tank are 2 astrai snails, 2 trotches snails and 4 hermit crabs and one dark crab with white tips on its feet

any ideas on what could have attacked my only fish dont want to add anything else till i find out

Cheers

Andrew

Dark crab? Hitchhiker crab? I'd say the crab, or possibly some other bad hitchhiker like a mantis shrimp or something.

Glass/bottle trick. Lean a glass against the rock at night with some food at the bottom (shrimp, flake, anything you feed your tank). Crab will fall in to get the food and won't be able to get out. If that doesn't work you could try making the bottle trap.
