Have you tried what the koi people use called KoiZyme? It's a
bacteria that out competes the disease causing bacteria. Ulcers in
koi caused the deaths of many fine koi fish a few years ago. This
does work as it cured the last ulcerated fish I had in less than 2
weeks. We never saw another ulcer since using this product every
summer. Most FSs that sell koi and pond supplies carry it.

Ulcers on koi are usually pretty easy to treat. They are generally
just
infected injuries. We normally just catch the koi and salt-paste the
wound. It's the cheapest way to do it and it is effective. It's a
business, so they always prefer cheap and easy.

Ulcers on gouramis are quite a different story. Left unchecked it is
rapidly progressive condition that quickly destroys much of the fish's
flesh. It spreads from fish to fish quickly as well. Do a search for
Epizootic Ulcerative Syndrome on the Web and you should find some
photos of
what it looks like. It looks more like flesh-eating disease than
anything
else.

I don't think introducing competing bacteria would be enough. It is
generally believed that a fungus plays a major role in the disease.
Once
affected a fish's flesh almost completely wastes away within days.

I think I've dealt with EUS, though then it didn't have a name for us and
we blamed it on poor genetics and the hormones the Asian breeders were
using to force the fry sex ratio to all male DGs. The last time I
treated it, I had some success with some strong anti-fungal medications.
I would remember their names if I saw them again. It made the water a
fluorescent yellow color (furnance?). It did not work very well or
quickly (seemed to only halt the advancement, and then the recovery was
very slow). It was successful (luck? chance?), though we learned that
the appearance of their recovery was only about 2/3 of the required
treatment period. Very pernicious disease. Many hobbyists report it.
During the worst periods, we would simply stop buying gouramis, or divide
them into separate tanks to reduce our losses if one brought it in (very
quick to infect other gouramis, and probably Bettas & Paradise fish if
given the opportunity, but DGs seem to be the most susceptible).
Syndrome sounds right, not a single disease, so treatment is slow.

If I was to stock gouramis in home tanks, I'd go with Chocolate gouramis
(sweet), Liquorice or Croaking, and for something bigger, Thick-lipped
gourami (like an oversize DG) or Moonlights or Pearls. DGs are cute but
over-rated (imo) and heavily exploited in the farming trade. jmo
