Sick neon please help me diagnose

So I thought I would start a new thread today. Since there was such confusion (on my part) last night.

I have a possible sick neon tetra. Their is a pale yellow spot on both sides of his body. Hubby is trying to get a picture now. He is a baby neon so its really hard to get a pic. I can't test my water parameters but I do daily 25% water changes.

1) I was feeding them food that was at least 6 months old-possibly over a year. I didn't know that food went bad and it was given to me. I switched them to new food today. Could it be malnourishment? All of fish are healthy and look well fed.
2) The yellow seems to be under the blue stripe. The blue strip is still visible. It wraps around his body.
3)He doesn't seem to be exhibiting any other signs of NTD.

NTD checklist:

Restlessness and sensitivity. He's swimming fine and rests at yet. I used a flashlight to check last night
• The fish become more isolated He's swimming with the school
• The fish has difficulty swimming He is swimming normal
• The tell tale white/ pale tissue appears. yes there is the pale yellow
• As cysts develop and produce more spores, body may become lumpy or irregular. Body does not look lumpy
• Often in advanced cases spine may become deformed or curved. Spine looks normal

I will post a picture asap. Thanks for all your help.

Picture



The white that you see looks more like a pale yellow and for some reason I can't see the blue in this picture but I can see it on him in the tank. Still trying to get a better pic.

Got a video, uploading it now. Don't mind my messy tank. My pleco dug up most of my plants again along with the weights. I spent $20 on weights thinking that would stop him lol.

just wanted to bump this up. Hoping someone can help.

Thanks so much for replying shawn!!!

Does that mean that you don't think its NTD? *feeling relieved*

Someone suggested last night before I had pics that it could be ich so I added some salt to the tank. I do have a filter that provides a lot of aeration and water movement. I will add an extra airstone now for extra o2.

I can't test the parameters because my new kit hasn;t arrived yet. It should be here tomorrow. I can only text the ammonia tonight and its 0. I've always done daily water changes of 20-25% to clean up my plecos poop so that parameters should be ok.

For meds I have jungle fungus clear, jungle bacteria clear, melafix, marcyln, and aquarisol. However, I don't know what I can use because I have snails (which I can remove) and I have adf's (nowhere else to put them).

Also I was bad about the quarentine. I only have the 20 gallon and the 2 3 gallons. I put the babies in with my betta but after 4 days he was chasing them around. They looked perfect then, so I moved them into the 20 gallon. I should have moved the betta into a 1 gallon.

I was wrong about the jungle med. I have jungle parasite clear tank buddies. Ingrediants are praziquantel, diflubenzuron, metronidazole, acriflavine

Maracyn has erythromycin Thats the only ingredient listed.
