Hello Everyone,
I have a suspect fish in my small 20 L tank right now.
She is a formerly very healthy 1-2 year old GBR.
Planted Tank, planted substrate, RO water. Levels well in hand if only slightly acidic
3 Corys
4 Rummy nose
6 Cardinals
1 GBR
Recently noticed a growing lump right at the base of her left pectoral fin. Has been continuing to get larger for the past 2 weeks. My research online has mostly come up empty.
I have treated the tank as a preventative with Melafix, Pimafix, and Salt with no change.
The Rummys are still healthy with full color so I know the water is good. And she doesn't seem distressed by it.
Any ideas? I dont want to remove her to QT until i have an ID/ plan of action?
