Well, I had planned to get a male betta for a while now, and since the parents won't let me get another tank going, I thought that one would do well in my 50g tank. I know that my fish are all rather active, but I've never seen them exhibit any real aggression. I went ahead and found an absolutely beautiful crowntail betta... I wish I had a picture of the little guy. His face was a very dark red, perhaps 2-3 shades past maroon, the middle of his body a very vibrant blood red, and towards where his tail started he had a lot of irridescent green. His fins were blood red too, but they had sky blue tips. It was quite possibly the most beautiful betta I'd ever seen. I brought him home kinda late at night (I went to my buddy's house to talk about some stuff and just kept him in his cup on the table we were sitting at) and decided to get him in the tank before I went to bed. I actually got him in the tank at 4am, and when I woke up this morning, I couldn't find him right away. I didn't think much of it, figured he was hiding, and went about my morning routine before work. I looked back during feeding time, and didn't see him come out to eat, so I investigated a bit more. As I scanned the whole tank, an irregular-looking piece of "gravel" caught my eye, and then it hit me. My fish killed the betta. All that was left was its skull, and a section of its spine with a small piece of flesh hanging off of it. I couldn't believe it... and I've been pissed off about it all day. I just wanted to share my stupidity...
