Ok this one is not too funny. I needed a snail to put into one of our former betta tank so I went to petsmart. I bought a snail and came home and put it in. The betta was very content for the first couple of minutes until the snail actually emerged from the shell. The betta freaked. He attacked the snail killing it. Well unfortunately the betta died a couple of weeks later from eating the snail. Sad..
