Help needed with my Severums.

[Aurika]

Since I bought my last severum , which was 3 month ago I started to have problems. My 3 severum has white marks on their fins . I don’t know if it is ick or fungus. Don’t know what right treatment to choose. And it’s only severum that is suffering, other fish look good . I tried to get best pictures. If need more I’ll try to take more
Ammonia 0
nitrite 0
Nitrate 20-40 (my tap water is 20-4

try regular aquarium salt then melafix

Would add some salt 1 tsp per gallon and increase water changes to keep the nitrates 20ppm or less.

Id like this but I dont trust melafix or pimafix at all. Salt is cool though!

But my tap water is about 40ppm . Do weekly changes with 45to50% of water change

But is it ick ?

Doesn’t look like ich.

Doesn’t look like ich.

What is it then ?! I don’t want to loose my babies I used medicine for ich. Maybe need to get something antifungal ? And why is it only severums like that. All other fish is good

Could be beginning of fungus. Maybe large broken area of fins. Would keep the water clean and salt. Post as it progresses.

I’ll try to look for different treatment, I’m not sure if I can use salt because I have pleco. Will post if they improve
