I have had the small one, named Pedro, for almost 2 months. I got the big girl (think its a girl, not named) 3 weeks ago. I got them both from different times from the same LFS. They have been very entertaining, and I really enjoy having a tank in my computer room with them (literally if I turn my head to the right, they are 2 feet over). Pedro was a very scared little guy when I got him, and was alone in the tank. We eventually put my little black moor girl in with him, and they became best buddies. He immediately came out of his shell and wouldn't dart and hide whenever I walked in. Unfortunately we lost her last week. We have both been very sad about that. He is learning to be the only small fish in the tank now, and is getting more comfortable with biggie. I actually took some time to get pictures finally of them.
