Ok I got two more nightfish that also got sick or injured.

The small one appears to have abrasions on its side (probably ammonia burn, hence the water change done in response to this)

The adult is the one that worries me. It started off with a fungus on its lower lip (probably after a wound from ramming into something in the tank), then the fungus disappeared but the wound got bigger and just this morning, I found that the whole lower jaw was split in the middle.

No good - can’t open the links so hoping they come good and doesn’t morph into bacterial infections.

You've got something funky going on... I'd say your water quality isn't where it needs to be... Before you say, "it is"... Test it. I'd also say that any native fish (puddle pirated or purchased) should be dewormed and defluked ASAP and fairly regularly. 

Week 1:

Review filtration, tank stocking and decor that makes the tank hard to clean/unhygienic.

Test your water.

Change 50% of your water.

Test it again.

Treat for worms and flukes.

Week 2:

Test your water.

Change 50% of your water.

Repeat week 2 every week forever.

 

I have read that these fish are hard to keep but that is not my experience.... Feed the crap out of them and keep them in good water with excellent filtration and they should be fine.

The display tank (now pretty much empty, save for a couple shrimp as a food source) is definitely gonna go through a rescape, with far fewer rocks, less of a blackwater look (no plants, lots of leaves and sticks) and more of a clear stream look (a couple rocks and vallis). This'll not only make it easier to monitor the fish but reduce the problems that the leaves might make, if they start to go funky.

 

I don't think either of them have any parasites (though the last one that died did have a swollen chest (technically the area between the pectoral fins)), the little one didn't have anything other than a bit of fungus on its body and the bigger one has been in captivity for a while now and probably didn't catch anything. But yeah, treating wild caught fish is a practice I'll start doing.

 

DT has been setup for a while now, I don't think it's a ammonia/nitrate/nitrite problem, I've been keeping up with WCs, plus it's never had more than a few small nightfish. I've also upped the filtration, with a stronger filter.

 

The quarantine tank is run on an air stone, with weekly water changes and aquarium salt.

 

I'll go and test both the quarantine and the display tank water.

The little one bit the dust today, it was covered in more of those abrasions.

That sounds bacterial to me although tbh I don’t see a lot of parasite issues. The ammonia / chemical burns I’ve seen are generally black (like a brushstroke) on gills, fin tips, edge of scales.

I’d test water as well or get a shop to do it. Then can cross off list.

The surviving nightfish is only getting worse, the stuff on its mouth is now a large mass of fungus and flesh. The fish is clearly distressed, and feeding is probably very painful for it, I doubt that it'll survive, should I resort to euthanisation?

Yeh it's not exactly pretty, the poor thing :(

 

And yes, I'll get the water tested tomorrow to ensure that future nightfish won't be afflicted with the same afflictions.

Meth blue has never ever worked for me, I'll try and see if it does anything, but if not, I'm gonna have to put the fish down.

 

Edit: the water now has a medium blue tint, hopefully I didn't overdose but hopefully the fungus dies.

Looks like columnaris, so bacterial. Something like wardley fungus-ade should do the trick nicely. Keeping temperature at or below 24degreesC is key to curing it before it kills the fish.
