Orange warts/spots on molies loved by my daughters: will they die?

[Alf2021]

Have you tested your water?

Yes

If yes, what is your ammonia?

0

If yes, what is your nitrite?

0

If yes, what is your nitrate?

6

If I did not test my water...

1. ...I recognize that I will likely be asked to do a test, and that water tests are critical for solving freshwater health problems.

Do you do water changes?

Yes

What percentage of water do you change?

41-50%

How frequently do you change your water?

Every week

If I do not change my water...

1. ...I recognize that I will likely be recommended to do a water change, and water changes are critical for preventing future freshwater health problems.

I have had these mollies for over a year, they were born in my tank. Now those spots/warts have appeared. Someone can help?

Thanks for any help you can provide

Tank size: 35 gallons (160 liters)

tank age: 5 years

pH: 7,3

ammonia: 0

nitrite: 0

nitrate: 10 ppm

kH: 6 ºdh

gH: 12,5 ºdh

tank temp: 28

9 gallons (40 liters) weekly changes

I use in my tank : seachem prime, Fresh Trace, Acid Buffer, Alkaline Buffer, Flourish Excel, Flourish Iron, Flourish Nitrogen, Phosphorus, Potassium, CO2, Uv filter.

Inhabitants: 10 mollies, 1 labeo frenatus albino, 3 Synodontis petricola, varied plants.

No recent fish or plants additions to my tank.

Have no clue what that could be but seems like tumors. Hopefully someone will recognize that issue.

Can’t help with that but I’d suggest not using the acid and alkaline buffers and messing with water chemistry. Most fish can adapt fairly well to different water parameters so long as they are stable. They don’t do well with fluctuations.

if you want softer water, use reverse osmosis water or add peat. If you want it more alkaline, add crushed coral.

Thanks.

Are they acting off at all?
Seems like it may be some sort of bacterial infection, whether something treatable or something worse like mycobacterium.

 

[Alf2021]

They are acting normally.

Seen on a similar fish and was diagnosed with lymphocystis.

According to this site https://edis.ifas.ufl.edu/publication/FA181 this would be good news: “lymphocystis is usually a self-limiting disease, meaning that, in most cases, the lesions will clear up after a few weeks in warmwater fish species”.

Correct - it often is a sign of some stressor (often poor water params or diet) but the virus itself is generally harmless.

The only difference I noticed in water params when this came up was in the temperature. It got really hot here where I live, 32°C 89.6°F. It usually gets hot, but not that much. But all these fish were born in my tank, they were supposed to be used to the heat.
