So, recently i added two more Pink Jewels to my tank, all were fine except one, who always hid in the corner. I expected he was just adjusting to his surroundings until today I noticed his eye was swollen and his color was faded. Must've had it at the store, because my water is near godliness in cleaniless. So, after much research, I am going to go get some Melafix today, and I'm doing a 70% water change. Other than that, not much I can do. Any tips or advice? Will Melafix affect my plants, shrimp, tetras, loaches, or filter bacteria badly? Advertisement says it doesn't, but I'd like some advice.
