So I got a new betta after my old one died, and I noticed on my heater there was a little bit of fungus that I missed! I immediately took it out, scrubbed it off with the hottest water I could stand and have it sitting in some salt water. As of right now, I have Epsilon (the new betta) sitting in a salt bath. Is this enough to save him? He had been in his tank for an hour or two before I noticed.
