Masacre in the livingroom

2 days ago I walked into the livingroom and found a masacre in the fishtank. My turtle (Spike Lee) had murdered one of my fantail fish. Took her head off and left pieces of her all over the tank! I don't know what had gotten into him. Did she give him a dirty look? Were they fighting over tank space? I have no idea. I grounded Spike for the day, cleaned out the murder scene and bought him a dozen more large minnows to keep his tummy full. When I repremanded him, I explained very carefully that we do not eat our friends even when we are upset with them or if we are hungry. And I also told him that if I catch him doing this to another one of our pets, he will have to move out to the pond at the farm. He agreed and Rick was a witness.
3 minnows met their maker that day. They also met Spike's tummy. So Spike was a happy, fat, alligator snapping turtle. He was taken out of the tank as usual around 11pm and put in his turtle house to spend the night with Scratchy (a female box turtle) who he has been living with for 6 years. When Rick got up this morning, Spike was standing on top of Scratchy and trying to escape the house to run a muck. So, Rick quickly relieved Scratchy of her room mate and put Spike in the fishtank where he proceeded to eat a few more minnows today.
And then later in the afternoon....it happened. I actually witnessed an atempted murder! Spike snuck up behind another fantail goldfish and snapped onto her tail. He shook her from side to side violently! I screamed at him to let go but, he didn't listen to me at all. The other fishes in the tank cried out "Stop Spike! Let Go!!!" But he didn't care. He bit higher until he touched her butt. By then I was able to rip his jaws away from her and pull him out of the water. That poor little fish was devostated! She couldn't even swim straight for about an hour and she may need therapy.

I decided to stick to my guns. Spike will be going to the pond in the morning. I hate to do it really. I've had him since he was the size of a quarter and he just turned 7 years old. He's never gone beyond the back yard but, he can't be trrusted anymore and it's possible that he could bite someone now. He's a big boy, about 6 pounds. I can do no more. =:o(
