Fish TB

What's this about, did you want to know if the fish has TB or do you want info about Fish TB (Mycobacteria sp)?
A curved body doesn't necessarily indicate Fish TB and can be from malnutrition, a growth (other than Mycobacteria) in the body, external protozoan infection, or poor genetics.
The following links have more info on Fish TB if you're interested.

Questions regarding fish TB
So I have been reading things in Manual of Fish Health and this forum and have a bunch of questions regarding fish TB: 1. Why TB are common in fish from south/asian farm? 2. Can fish get TB even if you don’t buy new fish? 3. I always have cuts on my hand (I don’t know how?) How many percent can...

TB, and effected fish…
So I’m not really understanding this, as it wasn’t around, when I had tanks 20 years ago ( or at least hadn’t been diagnosed ) Rumored to have come from Asian farming techniques… some fish species seem to be more susceptible to it than others ( my 1st experience, was with yellow axelrodi...

I didn't think wild caught had TB? Could it have been infected by existing TB already in your tank?
I have heard before about duboulayi with tb in the wild. I'm sitting in Canada so it's academic, but that is one of my favourite fish and I don't expect to ever see it, let alone keep it again.
As a general rule most wild fish populations don't have Mycobacteria. However, in areas around towns and cities, people release captive domestic fishes into the wild. These can transmit Mycobacteria into the wild so it affects native fish stocks. There are lots of introduced fish species in the waterways around Brisbane and Northern New South Wales. They all came from pet shops, and Asian fish farms before that. The fish farms in Asia are riddled with Mycobacteria and virtually every pet shop in this country and around the world has Mycobacteria in their tanks. All it takes is for one infected fish to get released into a local creek and that creek is potentially infected.
People also put used aquarium water down the drain and this includes bacteria that might be in the filter or gravel. Mycobacteria can sit in the gravel for years and can be sucked up when gravel cleaning the substrate and removed from the tank with the water. Not all Mycobacteria get sucked up but some can and it can go through sewerage treatment plants and end up going into a local creek or river as treated effluent. The best place for used aquarium water is on the lawn or garden outside where it gets exposed to sunlight. People also flush dead fish down the toilet and again, any Mycobacteria can survive the treatment plant and end up in a creek. Dead fish should be buried of burnt.
There are various fish farms around the country. Some are government run and some are privately owned. Most fish farms have Mycobacteria in their systems and this can easily get washed into natural waterways when there is a storm. Queensland and New South Wales are regularly inundated by massive rainfall events (the most recent was a couple of weeks ago, cyclone Alfred) and this can wash infected fish or contaminated water into the local waterways where various disease organisms can go from commercial ponds to local rivers. On top of this, a lot of government fish farms actually release captive fish into local waterways for recreational fishing and this can introduce Mycobacteria into local waterways. This is extremely common with government run trout farms in the south-west of Western Australia but also occurs right around the country.
If your tanks have ever had Mycobacteria in, or you have had aquarium plants, fish, crustaceans or water from a pet shop, then there's a good chance your fish have Fish TB.
