Wow, there is a new development in this ich saga...my female betta, who has never been NEAR the other sickened fish, has a bad case of ich! I don't know how she could have gotten it, but the two cases just have to be related. She lives with me at college, in a 2.5 gal on my desk, but I brought her home for Thanksgiving break, and now 2 days after I got back to college, she is covered in ich spots and her fins are clamped. AAAHHHH! I don't have a heater for the tank, since the room temp stays at 80 all year, so the water temp is usually 78, but I do have a 15 watt incandescent bulb that came with the tank that emits a lot of heat. Just a few hours after plugging it in, the temp in the tank is up to 84. I do have a small ammount of aquarium salt with me, but I don't want to dose too heavily, since the tank is so small. Parameters are perfect, but I could do vacuum water changes if it would help and not stress. Thoughts? I can't imagine how she got this! I'm sure she's a little stressed from the 4 hour car ride, but we were incredibly careful to keep her tank far away from the diseased tank, equipment, and the sink. I have a male plakat that also lives with me at college who is just fine, no ich spots or strange behavior, and his tank was right next to hers, in a different room than the diseased tank. This is just really horrible
