I have a question about a growth on the bottom lip of 2 of my 3 Neon Tetra.
The growth looks like a ball, it is not fuzzy like cottonmouth. I have read that it might be a fungus but I would like to find out if there is a solution to the issue.
My Tank Parameters (tested this morning with API Freshwater Master Test Kit):
Ammonia: 0 ppm
Nitrite: 0 ppm
Nitrate: 5 ppm
- 10 ppm
Size: 10 Gal
Filter: Unknown Waterfall type Brand but uses Topfin PowerFilter 10 with a mesh cloth and charcoal inner.
The tank has been stocked with fish for years. Generally the fish live a long time (years).
There are 7 fish in the tank.
1 x Green Cory Catfish (1")
1 x Albino Cory Catfish (1")
3 x Neon Tetra (1")
2 x Blackskirt (1.5")
I vacuum the gravel once a month and do a 1 gallon water change at the same time. I prepare my water the day before and use a tap water conditioner.
The fish in question were added on October 10, 2018.
The most recent addition to the tank were the two Cory Catfish on March 1st but the growth on the Neon Tetra was before that time.
I feed the fish the same brand of Freshwater Flakes, there has been no change in the food.
Thank you for any assistance you can offer.
