Hi there! I'll start off by saying I'm obviously new here. I had wanted a betta to take with me to college, and a fish that is content in a small space was what I was after.
There is some white fuzz that has begun to grow around the head and a tad on his tail. I do not know how to take a good picture of fish, so this is all I have: http://i.imgur.com/6DZpz.jpg
you can still see the white somewhat.
My first betta died from this white fuzz, or so I believe. I thought it was the chemicals that came with the tank, so I bought a name brand (TopFin), cleaned the tank, retreated the water, waited a day, and got a new one. Whatever affected the first has managed to stay in the tank and take hold of the second! I was not fortunate enough to have found this site during that misadventure.
I don't know what to do, I don't want every betta I own to die :<
1.7 gal tank
Filter, but I don't turn it on (it seems a bit too strong for the betta's liking)
No heater yet, but the temps are around 75F. (He's plenty active; I plan on getting a little disc heater when I go off to college)
TopFin Water Conditioner (says 5ml for 5gal, I put 2ml in)
Aqueon betta food (been feeding him 6 pellets / day)
Money for meds isn't really a problem, I just need to know what to do and how to do it asap. I still have the container he came in, I'm thinking of treating some water and throwing him in it real quick.
(P.S. to those who have made the extremely detailed betta guides: thanks! These have helped a ton)
