Yellow Coris Wrasse fin injury

[sgroff04]

I’ve had my Yellow Coris Wrasse about 3 weeks in my 75 gallon display tank. A few days a week I wont see the wrasse for a full day. Then it will appear swimming around the tank and eating normally.

Yesterday the wrasse never appeared. This morning it had a large chunk of its fin missing. I think I see a faint white mark on its side?

Seems too big to be from the larger of the two clownfish I got 2 months ago? Included a picture of the larger of the two clowns which is about 2.5 inches. I’ve never seen the clowns chase or nip any fish.

My other inhabitants are small blue legged hermit crabs and a pistol shrimp paired with my watchmen goby.

I’ve noticed the wrasse hasn’t settled on sleeping in the same sand spot at night and I’ve even seen it sleep at the base of rocks with only half its body in the sand. My sand bed is around 1.5 inches. Deeper in areas where the pistol shrimp doesn’t thing.

I had a firefish goby totally healthy disappear two weeks ago, never found its body.

My hunch is it tried to sleep near the pistol shrimps burrow?

Thoughts based on the pictures?

Sounds like fish is being harassed and a victim of aggression
Intimidation will cause this and you will want to find the aggressor and separate them into sump or acclimation box
One way to find who it is, is to set your phone on video mode for 20-30 minutes and walk away- YOU MUST WALK AWAY as they know you’re there
Drop food before walking away and come back and review video as aggressor is a jerk at feeding time

"Clownfish."

I don't know who gave them this name instead of vicious evil killers, or at least a common swear? I had not finished the first paragraph when I began to suspect that the OP has one, or two.

Welcome to Reef2Reef!

I agree that this is a severe injury. While clownfish are known to be aggressors in many tanks, this is a lot of damage, kind of unexpected.

Is the wrasse still eating well?

Thanks for the warm welcome, I’ve learned a ton as a lurker.

I’m still a little surprised this big of an injury could come from one of the clowns. The way the shape of the injury is I’m worried it burrowed near the pistol shrimp?

Could I have a predator hitchhiker that’s managed to stay out of my site? I haven’t heard any clicking at night other than the occasional click from the pistol shrimp. The tank is in my home office so I’m looking at it a lot daily

As for the wrasse, it’s still actively swimming around and eating well. I’m hoping it can recover.

I’m going to move the clowns to their own nano tank but I’m still worried this may not have been the clowns.

Good sign that it is still eating.

I also wonder about the pistol shrimp......

The watchmen goby and pistol shrimp have a new burrow at the front of the tank. Last night the wrasse was hovering around the front “entrance tunnel”. The pistol snapped at it a couple times when the wrasse hovered too close.

I’ve moved the clowns to their own Nano tank, who doesn’t need another tank? lol.

Hopefully my wrasse heals up and learns to stay away from the pistol shrimps burrow…
