Cyst on fish

[Skeptical_Mutt]

Hey all, long time no post. Well one of my glofish danios has what looks like an erupted cyst on the side of it. Pretty nasty looking. I put it in a hospital tank and salted it. Is there anything else I can do for my fish?

Hi
Could you give GH (hardness) and KH (alkalinity) which are important parameters.
Nitrate 10 20 not really a concern but
pH 8 is fine for Mollies (Platies, Swordtails, Guppies) but not for Danios nor Widow glofish.
Could you post some overall views of your tank please ?

cant tell due to slightly blurry picture but if there is an ulcer or sore on the side of the body, it will probably need anti-bacterial medication or medicated food. Probably cheaper to euthanise the fish if it doesn't get better in a few days.
