My betta fish has a really strong finrot. He started to show some black things on his fins and I started to treat him in his 1 gal quarantine. Before putting him in the quarantine he lived alone in a 5 gal aquarium with a sponge filter and a 100% waterchange weekly.
I started to treat him 3 days ago with 1 teaspoon of aq. salt in his 1 gal aquarium and added 2 drops of anti fungal and anti bacterial liquid (green liquid). I am doing 100% waterchanges daily and washing his tank completely (no soap, surely).
I am picking him using a cup (no net) so I dont damage his fins.
The problem is that his fins are gettin worser everyday! What am I doing wrong? In my country (Brazil) they dont sell Maracyn 1, Maracyn 2 and they dont sell jungle fungus eliminator. What can I do? My family is REALLY attached to this betta and he is considered part of it :/. Everybody is really sad asking me what will happen to him.
Is it possible to buy maracyn 1 & 2 + Jungles fungus eliminator and ship it express to Brazil? If yes, which site? I can pay up to 60 dollars if needed to save Oscar.
