Damn that's so random too... Any others show any sign of stress?Thx everyone! I fed some Whole Foods brand market prawns the night before. This is my routine, as I remove my driftwood arrangement during a water change to check for leftover shrimp uneaten. Instead I find my largest clown loach dead. So I can't blame the water company as this happened before my water change. The rest of the inhabitants are doing just fine.
