I was wondering if anyone could confirm my new rescue betta has a fungal infection. I am new at being a fish parent and want to make sure before I start treating it as one. The picture isn't the best. I will try and get a better one tonight. It does not look cob web (ish) but more like a patch under his mouth area. Also what is the best medication to treat a fungal infection?
5 gal tank
heated to 80F
Picked him up on Sunday, put in fresh water with 1 tsp of Epsom Salt per gallon.
After 24 hours started eating and is acting very normal.
Just noticed the patch last night.
