Troubling pink, fleshy areas on scales. Some coloration on fin too...

That's what I think will be best. I'm also trying to limit the amount of time the tank light is on to reduce his stress. If anything the tannins should help calm him down too.

Tannins will definitely help. I always use them for sick fish and young fish as well.

Here's some progress on his coloration. I have a strong feeling he is marbling...

[Sena Hansler]

I think he might be! We've seen this large difference for marbles before... Dark to light and light to dark.

Are those silverly scales normal? I don't really see any fuzz or cotton like appearance to them, they're more of a shiny color...

Just did a full water test:

Ammonia: about .05 to .1 ppm
Nitrate: 0 ppm
Nitrite: 0 ppm
pH: about 7.5

He seems to be acting really lethargic, I'm going to do a 50% water change just to be safe...

[Sena Hansler]

That would be a good idea to do a water change.

Ammonia should not be present in a fully cycled tank, and there should be some nitrates. It sounds like it's still cycling then.. It's a good idea to test daily and do a 50% change any time you see as little as .25ppm. It's gotten way to high at this point..

What filter are you using and how have you maintained it?

How long has the tank been set up?

100% water change does not hurt your cycle. The bb is in the gravel, decor and mostly filter, but not suggesting you do this. Just need to monitor more closely

[Sena Hansler]

Callistra they know it's going through a cycle :p However, I believe it is two water changes a week for a 5 to safely get the fish through the cycle?

[callistra]

Not if it's reaching that high of ammonia it's not, unfortunately. 1ppm is way too high and .5 is really not ideal either. Personally, I never cycle without testing and just assume a couple water changes will be fine as you will have spikes that go unnoticed. Some people do it and if you have hardy fish you may get away without noticeable issue or just some minor fin rot.
