Why do little kids get crazy ideas and accomplish them but in a very mysterious way.Well, my son put my pacu in his community tank, mind you he was 5 he asked if "pacfish" can come play with his fish. I gave him the go ahead ... While I was sleeping. The poor fish lasted only about an hour. the wife woke me up and told me what happened. I was baffled on how he put my 11 inch pacu in his 5g tank. He and i now laugh at the experience.
