I think that Tie is going to make it out of the woods. All of the white stuff is gone, and I've almost beaten the fin rot. I picked up some Melafix today at Walmart... better deal than the betta fix, so I guess I'll try it. The only thing is, that one dose is 1tsp per 10 gallons, so I bought a 2 gallon pail and put 1/4 tsp in it, just bringing it up to temp.
I'd like to thank everyone who gave me tips on how to help my baby...
