My friend/neighbor has recently gotten a betta(she got the idea after seeing all mine) and now its come down with something that I can't figure out..
First of all he's kept in a 1.5 gallon bowl(not my recommendation, but its what she wanted), its heated and she usually changes his water once a week. He's been doing fine for a couple months.. She said she got lazy about cleaning and didn't change the water for a while until yesterday. I visited her today and saw her fish pale, with his fins severely clamped! She didn't realize it was a real issue, she just thought he looked weird.. He's still eating at least, but he hides under plants and is very lethargic..clearly a sick guy. Its a shame because he's usually a breathtaking red half moon..
I told her she should change his water every day until he's better while using aquarium salt. Any other suggestions? The main symptom is the clamped fins which could be ick or red velvet disease but there's no sign of white spots or red patches. Any ideas?
