Large patch on Blenny..

[Odysi]

I just got home from being away for the weekend and found my bi - color with this big white patch and what looks like maybe damage on scales. Not sure what this could be. Any help would be great thanks all.

Young bicolor blennies have white vertical lines on them, but that patch looks a little concerning. Especially in the second pic. Any corals/nems that could have stung him? How long have you had him?

 

[Odysi]

None in the tank that would sting him. I have been fighting dinos the last week with some peroxide dosing but that's the only new thing added to the water.

How is the fish behaving? Any labored breathing, flashing or lack of appetite?

 

[Odysi]

He was ok. Ate fine when I feed the tank last night and swimming with no issues last night. I will see if he is any better or worse when I get home. He was in the rocks this morning before I left so I didn't get a good look.

Looks like a sting to me, but I could be wrong.

Only 2 corals in the tank at the time was a zoa frag and a green mushroom. I have 2 emerald crabs and a cleaner shrimp and other cuc but I don't think they are at fault.

So it looks like it's healing up abit. I have been watching it closely and it like to swim.in front of mu return I wonder if he just got blown it the rock and got scraped up.

you might want to get a light and check for other unknown critters in your tank that might only come out at night.

I know people say emerald crabs are "safe", but IMO a hungry crab is always going to be an opportunistic predator. Just last week I watched a pistol shrimp grab a perfectly healthy firefish that wandered too close to the shrimp's hidey hole - and those are also considered "safe".
