My Motoro's eyes turned all cloudy over the past two days. I don't know what is wrong. I did a 50 percent water change today. No measurable nitrite or Ammonia. Nitrate lower than 5 before the water change, about 1ppm now... He ate 2 nightcrawlers this morning and it hasn't seemed to affect his appetite any. I found a shed stinger in the tank yesterday, could he have potentially stung himself on it? His tankmates are currently 2 Angelfish who completely leave him alone, and a peacock eel who is absolutely terrified of everything. Here are some pics:
