Illness & Symptoms

In a few words, can you explain the symptoms? - redness around the eye, skin erosion, hemorrhaging, lethargic
Have you started any treatment for the illness? - yes
Was your fish physically ill or injured upon purchase? - no
How has its behavior and appearance changed, if at all? - much better now

Explain your emergency situation in detail. (Please give a clear explanation of what is going on, include details from the beginning of the illness leading up to now)
Not really an emergency, trying to figure out what to do next. Treatment for the illness: Removed carbon. First I thought he had some bacterial infection and treated the fish tank with Maracyn (erythromycin) for directed 5 days, but the symptoms didn't go away. Started to research and seemed like it is HITH, so started treating with API General Cure and added VitaChem to the water column and soaking food with Vitachem. It helped, the redness went down, skin erosion stopped, no hemorrhaging, but he has scar tissue (will it dissapear with time or can it be removed?). Keep adding vitamins to his diet and he is back to normal behavior. Just wanted to know if people had it with their bettas and what it is. Thank you.
