HELP! Fish seems to be sick

Hi everyone

I noticed my pristella tetra looks a little off today; his colors aren't really showing and he's just staying in the same spot. Upon further examination, I noticed there's a red line in the lower half of his body.

What could this be??

I will attach a photo. He is on the top.

5. How long the aquarium has been set up?

6. What fish do you have? How many are in your tank? How big are they? How long have you had them?

7. Were the fish placed under quarantine period (minus the first batch from the point wherein the tank is ready to accommodate the inhabitants)?

8. a. Any live plants? Fake plants?
b. Sand, gravel, barebottom?
c. Rocks, woods, fancy decors? Any hollow decors?

9. a. Filtration?

14. a. Have you treated your fish ahead of diagnosis?
b. What meds were used?

15. Insert photos of fish in question and full tank shot if necessary.

Animal testing is a terrible idea; they get all nervous and give the wrong answers.

Okay I'll answer those to the best of my ability.

10 G tank
Temp: 78
Aquarium has been set up for a year this month
I have 6 Pristella Tetras, I have had them for about 10 months
The fish was not placed under quarantine
Planted aquarium
No fake plants, no other decorations
Both filtration and a heater
There is a lighting schedule, the lights are on for about 10 hours a day, turned off for the rest. (daytime, light is on and off during the night)
Very little sunlight exposure

I change 50% of the water about once every two weeks. Tap water is used.
Sand is vacuumed during this water change

They are fed flakes, twice a day.

All the other fish seem fine, nothing abnormal other than the one fish I'm talking about

Fish have not been treated

going to assume since u didnt put up ur ph ammonia nitrites or nitratrates you dont have a test kit, thats ok but, not knowhing the levels i would change water once a week at 50% just to be safe ( i keep my tank water clean enough as if i would want to drink it) not sure exactly what he has going on and if this is the first day youhave noticed it may be nothing. dont ever underestimate clean water and a fishes immune system. i would keep up with water changes and keep a eye on him. i cant throw a guess to whas going on but as i said stick with the w/c and maybe add soem Aquarium salt and let his body heal on its own.,

I just tested for ammonia and there are no traces of it. I won't bother testing the rest because I just changed the water three days ago so I doubt there's anything wrong.
