Unhappy Recurrent Septicemia in Fantail Goldfish Need some help.

Okay here it goes.
I have had a 25 gallon freshwater aquarium setup that I have had for around 7 years now.
One of my fantail goldfish has been having recurring septicemia showing in his rear fins/tail. It will appear out of nowhere and within a few hours of me noticing, parts of his fin/tail at his rear start to fall off and it becomes super red in colour with white patches. When this happens he still swims normal and eats fine. The only real symptoms are the bloody ragged tail falling apart. My other black moor and pleco never get sick. This happens to him every month for the past year/year and a half. He is not being attacked by anything in the tank. Water quality is perfect and I have been keeping some salt in the aquarium to help. I have tried Sulfa drugs/tetracycline/minocycline/ nitrofurazone and kanamycin. Every time I have treated, the fish has responded to the treatment and within a few days everything looks good, and after the treatment he will remain healthy for a few weeks. Every time I have used antibiotics I have used proper dosing and proper duration as listed on the packaging, and usually go over the suggest time frame of treatment by a day to be sure. This is now the 14th time he is showing symptoms from this. I do not know what to do anymore. I cant afford to treat this as a chronic incurable illness. I hope someone can help me out there.

It is stocked with 2 fantail goldfish (One gold, one a black moor) and a pleco.
The goldfish are roughly 7-8 years old and the pleco is around 6 years.
They have been kept in the same tank for this entire period.
I perform regular water changes (25%) every 1-2 weeks and use seachem prime.
Lighting is by c5 bulbs. No direct sunlight.
There are a few plants in the aquarium(live) that are doing great.
I feed once a day and all food is consumed within 1-3 minutes.
Water is always crystal clear.
Have tons of aeration by a power-head and bubble disk.
There is a heater in the tank to maintain water temp.
There is good water movement but not too much so they are blown all over the place.

Here is the current tank stats:
NITRATE - Very low
PH 7-7.5
TEMP: 72-73F
FOOD: New life Thera A + with garlic
Filter Media: Canister/ Fluval 205/ Chemical: Carbon/Purigen with biomax

Any help would be much appreciated as I am now considering euthanasia.

I decided to add a couple of pictures. I believe it is hemorrhagic septicemia. What do you guys think.

Okay so just an update...
I haven't been able to treat with antibiotics yet (Shipping as we speak) so I have taken to swabbing the red infected area with methylene blue. So far it looks like this treatment is working. The area I swabbed with this dye has healed quite quickly and the redness disappeared almost overnight, however the other side of his tail is now quite inflamed and large parts of the tail just fell off and are sitting at the bottom of the aquarium...
After watching the tank for a while, I can honestly say the other goldfish hasn't been attacking or bugging him even with his ragged tail. In the past 7 years I have never seen them try and attack each other or show any aggression, and the pleco just sits there lol

I have also decided to test KH and GH

GH: 80 mg/l (ppm)
KH: 45 mg/l (ppm)
PH: 7.5-8

Any help guys... Could it be something else other then septicemia?

Minocycline will be in by Thursday. And I will be treating with a new antibiotic; Metronidazole. I plan to treat the minocycline by soaking their food in it and apply the metronidazole in the main tank. I might also add prazipro to the main tank to help eliminate any parisites that the metro might not take care of. Im going to hit this with everything I can, if this fails, well then I have no other choice it seems. I will keep the antibiotic feedings to once a day for a month and the metro and prazipro per their specific instructions.
