I think my new female betta Rosy has the ich virus. I have had her a week. After feeding her this morning i took a close look at her and can see tiny white like bubbles under her belly, she has 1 bubble on the left side but quiet a number of them on the right side in a row. Now she didnt have them a few days ago but now its there and you have to look very close to see it. Here is a photo of her just now: I read on here that you can turn the heater up to 30c and that will get rid of it without medications. Should i first try turning up the heat in her tank? I have never had a fish with this before. The water in the tank is: pH 7.6 Ammonia 0.25 Nitrite 0.25 Nitrate 20 Should i also change the water? Is there anything else i should do? How could this have happened?
