How hard is hard and what minerals?
29.6.93 - Goyder Crossing - pH8.2; TDS 190; T 23.5C
Any idea what the water chem is in
Cape York streams in the wet season?
Sorry - never been able to get there in the wet but have never recorded a pH above about 6.5 in 5 trips at various times.

How do we really know the ulcer in the wild and captivity are not TB. If
the one in the wild isn't TB then isn't it more likely that the one in
captivity is not TB since many of us bring in wild fish to our
fishrooms? In other words, isn't it more likely that we have introduced
these "wild" ulcers into our aquaria?
Everyone keeps talking about TB this and TB that, but how many folks have
had it professionally diagnosed?
Sorry Peter but we have had Steve Pyecroft do about a dozen (or maybe double that) autopsies at various times when we were not sure and from memory 99% were TB. I hope he will be online soon and he can give us a more informed and accurate assessment of th
e extent of the problem in aquarium fish.
I want to hear from anyone who has and
I'll bet virtually no one on this list has. We could all just be wasting
our breath referring to literature on TB when it may not be TB. Do we
_really_ know it is TB????? Why do people feel so sure all these ulcers
are TB? I wanna hear the evidence.
I think some pathological work on deaths in wild fish ulcer epidemics have been done in the NT and other parts but they have turned out to be various combinations of viral. protozoal, bacterial and fungal prinaries and secondary superinfections on the dam
age caused. I can't recall reports of TB in the wild but I believe the organisms have been cultured/ recovered from natural substrates. Once again we should get it from the horses' mouth.
