Hoping someone can help. I purchased 3 reticulating hillstream loaches on Thursday 10/22. By Friday afternoon I found one barely hanging on the glass with white patches and red spots. He died before I could even get a clue on Google. I took him back to the LFS and they said he probably had a bacterial infection so I immediately started treating the tank with Maracyn. All looked good until today, I found one sitting on the substrate with the same white patches and he was gone within minutes. The third looks fine but whatever is killing them seems to be sudden and I’m afraid it’s just a matter of time. Am I treating with the right meds? Should I try something else? Water testing puts everything in normal range, temp at 74.5.
