Hmm... guessing they didnt get better? :/ did you try any treatments?
How strange that it is right by the things they move most often

Rainbows are lovely and all, but maybe I need to stick with a hardier variety? Or hardier stock in general. I could just go for a tank full of cherry barbs xD

Should I look at alternate stocking if these do pass? I can't keep just 2 rainbows... I'll either have to get more or rehome/trade them I think

me again!...

Lights just went on and OH tells me the water seems a little cloudy today... any possible reason other than bacterial bloom (normal in a cycled tank??)?
will do parameters after work...
I planned a 30% water change tonight to remove most of the ESHA gdex, before trying the anti internal bacteria.
Lump on the left fin/tail bulge one is looking a little bigger today too

Edit:
ammonia 0 & nitrite 0
Hygrophilia... emerging, tip of it burnt, perhaps a problem?

Plants that look burnt will be too close to the lights.
Did you do the water change? How's the parameters?

Yep, I hadn't noticed that it had emerged and was actually touching the bulb

Ammonia 0, nitrite 0, nitrate 0 or 5 at most, PH 7.2
Water change done, 1 cherry barb down and interpet anti internal bacteria dosed.
Also ripped out some more hair algae while I was at it, just plucked off the leaves as it is mainly on the hygro and that is going wild at the moment.

Now... the other male is acting weird. He was sucked up against the filter intake grid so I turned the filter off, let him get away and back on again,
he slowly floated down to the bottom and I can't find him now as it's dark... hope he's ok. The one that did a nemo was a bit of a douche, but really bright. This one doesnt do so much chasing around but is less red and more black.

Can I add melafix to make them feel nice along with anti internal bacteria? Haven't been able to find anything online about mixing these.. I mean its basically tea tree right?... or should I use aquarium salt (always thought this was some sort of gimmick/extra sale or not for tropicals, but its always on the interpet box)

What if... they're all infected with something but only the rainbows show it & the anti internal bacteria is working and flushing out whatever is wrong, but with side effects
Speculating what on earth is going wrong :/

Melafix is normally ok with anything else - I haven't seen any complications (except with labyrinth fish and pencilfish).

Well the little guys are still around, their lumps seem to be slowly growing. They don't have any outward signs that their health is deteriorating (and since it has been a month with noone dying or anyone else being infected, I'm guessing tumours is correct)

I've seen the male flirting with a couple of the females recently so something is going right there at least.

Now thinking about the hair algae and stock...

Sigh...

Why is this happening now?
I literally just added the x-ray tetras and noticed this. Tested the waters
0/0.25/5, pH 7.6

Did a 30% water change with prime to deal with the 0.25.. could it just be stress?

I think long-term ammonia poisoning can make the underlying skin go black, but it's a long time since I saw anything quite like that.

Hmm well, noone else is affected and other than 0.25 nitrite probably due to stress of new fish addition, there was no ammonia...

This one does have a "tumour" on that side on its gill. I've messaged the LFS who said they would have a look and see what they thought too.
Wondered if there was a problem with that batch but they said no when i was there yesterday...

I've been doing a little light reading......
Mycobacteriosis may be the problem - it does cause "blackhead disease" in rainbows.
The only treatment I can find is to remove the fish, euthanise and then burn the remains to kill the pathogen.......sorry if this is the case. :(
