Well, my otocinclus died randomly this morning. My whole family is sick, so we all slept in considerably, and I was getting cleaned up when I noticed him. He has no visible signs of injury, except that his defensive spine was out fully and his abdomen is slightly discolored. I was worried that Lily may have killed him, as she was chasing him more than usual yesterday. It's odd, because they usually get along. I've not had the water tested yet, but I'm going to get it tested today or tomorrow, weather permitting. Lily the female betta and Panda the panda cory are both fine... Any ideas? I've had him for several months now, with no issues. He even survived the great ich outbreak of 2009! Farewell my dear Otto, you were a fun little companion. I shall dearly miss your antics, and seeing you on the front pane of glass.
