Sick chromis?

[six foot]

One of my four chromis every evening while feeding a cube of mysis looks blotchy for lack of any better term. During the day looks normal swims normal. He is also the second from the top in the pecking order. I have had all of them well over a year and a half never any problems. He and his buddy control the middle of of the tank and keep the other two chromis to the right side of the tank. 6 foot 100 gallon. All other inhabitants also seem fine.

Is this common or a problem?

Best picture I can get. No red spots or open wounds.

I can't really see much in the pics.

Have you recently added any fish or coral? Anything wet?

No not in a few months. Fighting conch 2 and 3 shrimp back in July.

Sick Chromis is almost ALWAYS Uronema.

Looking more closely at the LT fish...you can see the big spot on the tail. My money is on Uronema. I can't bet you if I did a skin scrape of that area I could confirm that.

IMO, API General Cure is probably one of the best treatments. You can treat internally and believe me...they will be there.

I've hit fish with literally every medication under the sun and they still died because it was internal. Had I been able to get the fish to eat the food soaked with APT GC, I'm fairly confident a few would have made it.

The only problem with Chromis is that due to their hyper activity, they burn through their oxygen, get into respiratory distress (rate of breathing is like 100x or more a minute) then die from hypoxia.

My next experiment is running pure oxygen with these fish to see how they respond.

He eats like crazy and is very active. During the day the best I can explain is a lack of color in a few scales. I only notice it during feeding at night. No sores anywhere.

Any raised scales?

I agree it’s likely uronema but we need a clearer photo

Yeah that's almost classic. If the fishes immune system is OK...he may be able to fight it off. If not, you'll notice a larger vertical pinkish-red lesion starting to form. Then comes the rapid breathing. And if not treated...death is sure to follow. This is by far the worst thing I hate to treat. The problem is it goes internal and when a fish is sick...you can't get them to eat. You can completely clear all external issues, but the fish will still die. This is why I've be doing a lot of research about injecting the fish with the proper medications to treat internally. The problem is that there are risks involved just like anything else.

This is the same fish this morning. The spots only appear during feeding time. Kinda strange I know some fish change colors when feeding but have never had one in my tank do that. It's more like a lack of color on a few scales. He's is also the first to come out of hidding when the lights come on in the morning.
