I was notified by Mark yesterday that our friends bought a house that had a lot of "junk" lying around that was included with it.. well, there is a 55g tank w/ 2 arowanas in it, as well as 2 huge cory cats and some undetermined other fish.. but we can have them! I have always wanted an arowana; my friend kept them for years and they are just awesome, and i saw one years ago in some music video and was captivated by it. They get huuuuge.
This is what they look like (this is a googled image, not mine.)

I am going to have to move some goldfish around since they want to keep the tank, but I am excited! Anyone ever keep these before? They eat live, right (fish, crickets.) I am thinking eventually they can go into our 125; they are small now, I have just been told. A 55g should be ok for a little while.
