Today after his water change Mellow died.


I have no clue way he had just stared tail biting. I'm really upset beacause his was always sooo happy to see me and now he's gone. I think him may have died beacause I took him out of his cup 4min early, Could that really kill him?? I added aquasafe and even mixed warm and cold water so the water wouldn't be to cold or hot. Was just his time??
