There are at least a couple of Public Aquaria I am aware of where Piscine TB
is pretty well entrenched. As Nick says though, this is a separate issue
from the one of AB resistance.
Myco is one of the few zoonotic concerns we have in the Aquarium hobby, and
it is a real 'Health and Safety' concern, to the extent that I am not
allowed to recommend to students on work experience that they suck-start
siphons (although I then set a bad example by always doing exactly that). I
must admit I rely on a diet high in garlic, chilli and alcohol to kill off
any such bugs. Not very scientific but it's fun and it seems to have
It is having an extreme impact on some conservation/research initiatives,
including Seahorses, Cichlids, Killies and Goodeids, although there are
indications that husbandry may play a part in this.

Oh, I don't know, there are a few who might benefit......

Unfortunately very true, and even then the possibility of missing something
is quite high. It would be interesting to run a simulation by putting a
compound in an 'isolated' tank that will fluoresce under UV light, and then
go round after a week with a portable lamp and see how far traces of that
water had got spread.

Same here, when used properly they can be very effective, and it is true
that the fewer barriers they have to get through the better, so injection or
through food are the most effective ways to deliver this.
Antibiotics are available by prescription only over here in the UK, and
that's the way I'd like them to stay. Our vet at work is one of the longest
established zoo vets in the UK, and I thoroughly trust what he says based on
his long experience in zoological and aquaculture situations. He says that
antibiotic resistance really is something to worry about for both animal and
human health, and that's all I need to know on the issue.
