The fin rot started out as an ick-like spot at the base of the dorsal fin(wich didn't worry me too much as it was localized to the one spot), then became a small hole in the base of the dorsal fin and a lump under the scales on his back.
At this point he had been in a heavily planted 2-gallon for over 8 months, and i had missed a month's worth of weekly water changes, seeing the hole I set him up a heavily planted 10-gallon 80% full with an undergravel and tetra 3i filter. I let him adjust a week, and the hole and lump got bigger.
I started a treatment of melafix, according to the directions for two weeks. During the two weeks the lump stopped growing and he lost the back half of his dorsal fin. I stopped treatment, and the rot was on the pause for about a week and two weeks, then the scales on the lump(wich now extends in perfect half-circle halfway to his belly) turned gray and started to look like a scar.
I have given him a dose of melafix, but it doesn't seem to completely stop the rot. He really gets a good kick off of the melafix, but I have maracyn-two and eurythomycin sitting around also, as his rot gets worse I become split as to whether it's better to risk him suffocating to death in heavy medication, or be patient with the melafix.
I would like to breed him one more time, and he seems that he could get in the mood(when I quit the melafix treatment the first time he built GRAND bubblenests for two-weeks) but I don't want to make a mess.

WHAT SHOULD I DO? Please do not post unless you have seen this type of fin/body rot before.
