Symptoms and Treatment
How has your betta fish's appearance changed?
Began with noticeable red veining in bottom fin, along the edges, pale around the face. Has since passed. Second died Sunday. Third one is still hanging in.
How has your betta fish's behavior changed?
Was resting on the bottom, gills pumping about twice as fast as normal, occasionally going to the surface for a gulp of air, once or twice racing around the tank. Gill movement went back to normal after a few days, but still was resting on the bottom. He was Ďtail heavyí, couldnít suspend like normal, when resting on the bottom he was head down. Second one died on Sunday, so I didnít see. Third is just sitting on the bottom.
When did you start noticing the symptoms?
About two weeks ago.
Have you started treating your fish? If so, how?
Just clean water, changing daily.
Does your fish have any history of being ill?
First one was recovering from ammonia poisoning, fins growing back, about half way. The others, no.
How old is your fish (approximately)?
Less than a year, purchased about 6 weeks ago.
Steve is the last one. I've had him for going on two years, and he is just sitting on the bottom, has been like this since last week, started just before Jessie died.
*sigh* This is awful, and I'm thinking maybe I shouldn't have any more bettas at work...
