That's right, it appears to be a warm-blooded fish! Check it out! You can read more about it here as well. http://www.usatoday.com/story/tech/2015/05/14/warm-blooded-fish-discovered/27318727/

This is my friend Erin! I met her after helping with a water change. She is an awesome girl! Erin told me that she likes fish, and she has a red tailed cat-fish that will get really big... maybe bigger than me! I haven't seen a fish that big yet, but i guess it could happen if you take care of it well for a really long time. Erin was awesome, she didn't mind petting me even though I was a little damp! (I try to eat water that spashes... but it always escapes me!) Thanks
