Hi, I recently received these glowlight danios from a highly recommended online retailer. I noticed once they colored up, the little white spots on them and reached out to the retailer making them aware. Thinking this is Ich, they recommended treating with IchX. I've been treating with IchX at the recommended dosage for a week now and have noticed no changes in the spots. They are not spreading. Still same two fish with the same couple of spots. I read a bunch of sites that recommended increasing temp to above 80 to speed up life cycle, right now sitting at about 83 degrees. It's been several days since increasing temperature and still no change. I'm wondering if I need to keep trucking along with this treatment or try something different? I've never had sick fish before (been in hobby since 12/21). This is my first experience with Ich, if this is even what it is. Any recommendations would be appreciated. Water parameters: pH 6.4, Ammonia 0, Nitrite 0, Nitrate 5-10. Sorry for blurry photos, these fish are so fast, it's hard to get a decent pic.
