I - Don't- Get -IT! My cloud mountain minnows keep dying! Recap: -Found a tailess fish 2 days ago that died -yesterday I found another dead fish -today evening, one died suddenly, I noticed that one of them stayed rather low in the tank earlier, and would occasionally twitch it's fin to stay at the exact same spot for a while, seemed to be breathing rapidly to me, it didnt come up for feeding, I don't know if its the one that died. Aquarium is currently cycling, water was added last week on tuesday, fish added on last thursday, I did a 25% waterchange this tuesday and wiped the glasses with a sponge brush I had never used before. Water Test Results Temperature: 76F Ammonia: at most 0.25 Nitrite: below 0.25 Nitrate: 5.0 ppm These results have been the same all week to the point I wonder if my testkit isnt defective. Theres some algae on my wood and fungus, I was told it was normal and would go away on its own, here are some picture because at this point I'm trying to diagnose anything. Help?
