weird line on clown

so my lfs told me it was probably from stress. caused my ammonia salanity or ph.
my readings

ph 8.0 lfs said it was 8.2
nitrite 0
nitrate 0
ammonia .25
salanity 1.024 lfs 1.022

 

Is that clown holding it fins clamped like in the image?

Can you do a water change to provide some relief for the fish?

 

no he is moving them normally. just happened to be when i took pic.

i am making water as we speak. i think the ammonia is from the skimmer being off.

 

Is this the 180 gallon?

You should probably have some ammonia binding products on hand until you get a handle on the source of the ammonia. I have never had detectable ammonia when I turned off my skimmer or removed it.

As far as the white line no idea. I imagine the fish is compromised though and could benefit from Melafix with some Selcon. Hopefully once the ammonia level drop the fish will come around. Does not look like a parasite.

 

yeah i used some what is melafix and selcon.
selcon is the garlic correct.
yeah it is my 180.
the only other symptom is not eating to much but only been in tank for a few days.

thanks a bunch you are always quick to respond.

this tank has been harder than my 55 was for some reason?.?

 

Sure no problem.

Once the 180 gallon gets settled is will be easier.

And you're right, some clowns take a few to several days to begin eating initially.

 

so one more question. what else could be causing my ammonia if the skimmer off probably is not the problem.

 

so i found the reason of my ammonia spike i think.
a dead cardinal sally light foot crab is eating it, should i try and get it out or just let them do there job. could the crab have killed him cause he was doing fine or appeared to be doing fine.

 

So next thing is could an ammonia spike that small cause stress to do that to my clown

 

The white mark *might* be an ammonia burn. Or perhaps the clown scratched himself on a rock or something and left a mark. The ammonia could definitely stress your clownfish that much if exposed long enough. Also, remember that it could have been a lot higher before you noticed and tested for it.

I'm not sure how fast a Light crab is, but usually IME, when you see a crab, or something that is part of your CUC eating a fish is because it had died ( or was dying) already from something else.
