This evening when I came into my room, Sheldon had Fishy pinned under the filter. I shooshed him away and Fishy scooted out from under the filter. He was bleeding. Sheldon got him in the eye. Sheldon chased him and before I got Fishy to safety, he bit his mouth. Fishy stopped moving. I scooped him out and he was definitely dead. I flushed poor Fishy.
As of late they had been getting on each other nerves so perhaps this was coming eventually. The bigger question is, do I need to be concerned that Sheldon not only didn't understand how to kill Fishy or is this some sort of behavior problem? After all for a feeder fish, Fishy lived for 3 months before he was attacked. More worrisome is, does Sheldon have anger issues? Am I not feedng him enough?
