No, and the same went for the the "fishkeeper's finger" that I'm still
fighting with antibiotics. The temptation to do so was there, though.

Strict isolation, coupled with prompt removal of hatched babies from suspect
peat and its water, halted the few cases I had in their tracks. I've
actually lost more fish from a particularly virulent strain of velvet.

That's not to imply it can be taken casually, for the slow development and
surviving in damp peat can really spread it if you aren't diligent. Examine
carefully the intestinal contents of any mysterious Notho death. The white
balls are obvious. Never ship suspect fish or eggs.

I'm less convinced that bleach is a perfect sterilizer than some. I also let
tanks and equipment dry completely, preferrably in the sun. Nevertheless, I
have treated the two tanks with known *Mycobacterium marinum* with bleach,
and will dry them outside before reusing them. What hurts is to toss all
that nice Java moss and substrate material from 2 20G tanks (not to mention
the loss of 4 species of fish -- 3 were non-killy).
