Recently bought 5 lambchop rasboras and immediately noticed that two of them looked like they had fin rot. I tested Ammonia, Nitrites and Nitrates and they were all 0. One died the other morning so now I'm down to four (the one in the pictures with the white spot on the dorsal fin has passed). One now has a milky white film over his eye. My ph is 7.8 and I'm starting to think it's Columnaris since it thrives in high ph and one of my fish died practically overnight. I've done a lot of reading and need more opinions on how to treat this before it gets out of hand. They were originally in a planted 20g and I moved them all to a 4g and dosed 2mL Melafix (it was what I had on hand). Some people have had success with the Melafix and some have not. I haven't seen any improvement nor have they gotten worse. I'm still not exactly sure what it is either, so if you think it may look like something else please let me know. If it is columnaris, then i was thinking of adding aquarium salt to the 20g to kill it. I read that they will die from 1% salinity but I'm not sure how long it will take and if the plants can handle it. Has anyone had experience with this? Also, I was thinking of adding Hydrogen peroxide instead. It seems like a safer way to go. Please, share your advice!
