Pimafix is very bad to labyrinth fish.. It has an ingredient called "tea tree oil" that coats the labyrinth enabling the betta to get air. (Any med that has -fix has the TTO) It just suffocates them.. There have been few successes, but most led the fish to disaster. /: Sorry, I just don't want any members' fish to get worse... Besides ES and AS, I recommend: Maracyn, Maracyn 2, General Cure, Coppersafe, API Triple Sulfa, and API Erythromycin, API Stress Coat..
I think there's more but I'm not sure..
