Symptoms and Treatment
How has your betta fish's appearance changed?

Top of tail is disappearing, a little grey fuzziness on her, stress stripes from being in smaller QT container, clamped a little pale, little nodules on her tail fin.

How has your betta fish's behavior changed?
When did you start noticing the symptoms? 3 days ago -- I added anti fungal green tea extract and more Indian almond leaves

Have you started treating your fish? If so, how? Have just up ther into QT tank with 1 tsp of aquarium salt per gallon,

Does your fish have any history of being ill? She had a little fungus back in July which went away with smallest possible dose of BettaFix.

How old is your fish (approximately)? I got her in July she was young, so possibly 5 months old.

I am going to take the plants out, wash the gravel do full water change , and only out her back in after her course of salt is finished.

She hates being in the smaller container.

I feel like a bad mom, even though she has live plants and good food and PWC every other day or so.
