My white-bump-patch Gourami/Neon mysteries...

The symptoms:

Dwarf Gourami has a thing below it's eye/next to it's mouth that it's had since February. It is a bump sometimes 1/8" big, underneath the skin as well as reddish with a white thing perodically sticking out. I have tried salt for several weeks, which may have improved it but never got rid of it, and this gourami was also in the tank when I tried one round of Tetracycline for the neon problems.

This fish eats very well, is very active, has great color.

Sorry I can't get any more detail on this problem.


The neon tetras were bought in small batches and quarantined for 4-6 weeks each before being put in a newly bleach bombed and then fishlessly cycled tank.

They still developed strange whitish bumps sticking out of the end of their tails. Though it seems to get better and worse, one or two of them still have them. Sometimes I think they shimmy or shiver, but I am paranoid since I'm not sure I've ever seen normal behaviour in neons! They also eat very well, but sometimes I think they look bloated with the skinny part of their tails looking almost bent. (I wiped the tank before fearing I had lost half of my neons to NTD!)

And this was the fish on a VERY good looking day! It is much worse again.

As mentioned, no response to the tetracycline antibiotic, though I only did the 5 day run.

I still have 3 neons of the original batch which were covered in white and grey patches and those small white bumps that only appear by the tail. (Not ich.) While 3 died or had to be put out due to loss of swimming control and eating... the other 3 look almost completely normal again. Arrghh... what is this strange disorder that keeps reappearing! The ones that died eventually got real skinny, fins all but disappeared, and eventually they were bent and struggling to swim and control their movement. (And one mysteriously died when it decided to get squeezed up behind my filter and between the glass, with less than a 1/4" space! Not sure if it was disease or accident related.)


12 gallon
Fishlessly cycled (now twice over!)
Temp is 76-78
7.2-7.4 pH
0 Ammonia, 0 NitrItes, 10-20 ppm NitrAtes
I am not sure, but I believe it is Moderate in gH, but low in kH. I think 40ppm but the test is difficult to tell.

1 Dwarf Gourami
7 Neon Tetras
3 Otos

Water is changed 50% by gravel vac, and replaced with a 2/3 mix of bottled spring water and my tap water. (After so many months of diseased but not dying fish, I decided to see if maybe there is something mysterious in my water, so I'm trying for less tap water and more pure water.)


In my previous efforts, I have tried, over a period of two months... salt, Melafix, Pimafix, Coppersafe, Maracyn, Maracyn II, garlic, daily fresh water changes, Formalin Green/Anti-Fungus, and now Tetracycline, and nothing I've tried has worked. It seems that after 3 months, the old neons got better on their own, in somewhat less than a stellar environment (it was supposed to be a temporary hospice arrangement that ended up in them living alot longer, but in a small bin with less than ideal filtration, no heater, and water changes every 10-14 days.)

This is a photo of what the old ones looked like when they were sick:

Any input is appreciated.

Hmm... I've only tried high heat once, and admittedly it was only 84, but it seemed to me that despite lower the level of the water and having my air pump running... that all the fish really did become lethargic. Enough to worry me to bring the temp down so they would not be stressed as much.

I'm also worried because it was on a hot week when the temp went from 78-80 to 80-82 that the white spots on the new neons first appeared. (Which is what made me originally think it was bacterial.) And it did seem that most of them lost the white bumps except for one or two, after the temp of the water had reduced to 76. It was when I think they looked the best they had. (But then again, the things come and go so it's hard to tell what helped and what didn't.)

I did have a dose of salt running in the tank for some time, not higher than 2/3 tsp / gallon since the Otos looked like they were getting really bloated and weren't acting realy normal. I had thought it was shrinking the red bump on the gourami's face, but it would just come back a few days later, even with the salt...

I wish I could determine if this was bacterial or parasitic, because then I could tell which way to use temperature to my advantage.

I don't really see anything in the pics, but you may want to look into neon tetra disease. If the fish are getting bent, you could also investigate fish tuberculosis. Neither of these have a cure.

I wouldn't worry about the gourami, some fish just have "birthmarks" that don't cause them any trouble. Unless it frequently gets large and seems like it might pop.
