Some thing Attacking my Chromis

[Thomsona]

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.

How would I go about catching thesexhitx hikers crab or shrimp ,

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.

Here are a few pictures of one of the crabs I caught in a glass as far as I know there Is a bigger one in there still

It measures about 2cm body width and 1.5cm long

ew thats one ugly crab! What did you do with it?? I always keep any unwanted hitchhikers in the sump, not really possible if you don't have one though haha.

 

[hackteck]

what type of crab is that

 

[xxwolfpackof1xx]

might be a gorilla crab

 

[Thomsona]

Ok either way it's aggressive don't know what to do with it hoping to catch the bigger thing asap as well

 

[0o.Kelsey.o0]

Your LFS might take it in.

 

[Thomsona]

They said no to it so I have it alive in a container don't know what to do other the releases it at the beach

 

[0o.Kelsey.o0]

It might do fine at the beach if you release it into a rocky area, those crabs are very hardy

 

[Thomsona]

It's now living in my qt tank

Cheers

Can't catch the other one though

It's illegal to release any wildlife that's ever been in an aquarium back into the wild. Just a heads up. Turn it into sushi or find someone to keep it for you if you can't keep it.

I'd also get that other crab out asap. It probably can't fit through the bottle...You can go to the bait shop or academy or what have yo uand buy yourself a small plastic minnow trap...that might work.

Hmm never even thought of that, living in Sk I wouldn't be able to release anything saltwater and have it live haha
