My daughter's betta died a few days ago, I think because of a bacterial lump that developed just behind his gills and killed him in one day. It's been very hot this week, and the tank has been around 86 degrees. I put in bags of ice to help keep it cool, but unfortunately it did not save Ruby.
I did a partial water change, but now the cardinal neons in the same tank (6 gallon eclipse) look sick. They are hanging at the bottom and one has a black stripe on one side. Is this a fungus/bacterial infection? I put in some anti-bacterial medication. Will this help? I've had tanks for 15 years and have never seen this before!
Thanks for any help and advice.
