My betta, Benvolio, has a fungal infection (I think) and he doesn't seem to be responding to the medicine I got for him. He started out with a few white dots on the side of his head, which I thought was ich. I got him some medicine for that (APA Liquid Super Ich Cure
), but he didn't respond. His spots turned into a patch of white cottony fungus in the same spot, so I got him some general antifungal medication, Pimafix
. He's on the fourth day of treatment with that, but he is getting worse. He has always been a very active betta--nearly always moving even when he has been sick in the past, but for the last two days he has been sitting on his plant in one place with his mouth at the surface of the water, I think breathing with his labyrinth instead of gills. He only ate a tiny bit of his food today, also unheard of for him.
Benvolio lives in a gallon bowl with a small heater that keeps his water at around 79 degrees. I do 100% water changes once a week.
I'm wondering if maybe he is having a bad reaction to the Pimafix, or if I just caught the infection too late. Maybe the sickness isn't actually a fungus? Any advice?
(you can see the fungus in this picture--the white patch on the right side of his head)
Thank you so much for any help you can give me to get him healthy again!
