Dwarf Gourami with large growth.
#1
I noticed this growth on the fish 2 days ago. It has gotten much bigger each day.
It looks like it's kind of fluffy/fuzzy, so thinking its maybe fungal.
PH 7.4 / ammonia 0.25ppm / Nitrite 0ppm / Nitrate 10ppm
160lt tank setup for about 4 months
Fluval U4
4 dwarf gourami, 10 neon tetra, 4 corrydora, 7 male guppies, 6 endless guppies.
Effected fish has been in tank for around 3 months.
4 weeks ago, 3 neon terta had, what I think, was cotton mouth. I added an interpet anti fungus and finrot treatment to the tank. After about a day and a half I decided to remove the 3 tetra into a treatment tank and did a large water change to the main tank as the treatment was making all the fish very lethargic and not eating properly. The main tank returned to normal after a few days after the water change.
I left the tetra in the treatment tank for 2 weeks. Replace their water and retreated. But they didn't recover and passed.
Any advice would be greatly appreciated. If this is cotton mouth/finrot related. Any recommendations for treatment?
Cheers
