So I was at an LFS today and they had a 6 inch african aro for sale. He "followed" me around the room from his tank and bobbed up and down whenever I approached, going so far as to stick his head above water. The owner said that he only did that for certain people. He acted like he wanted to jump into my lap like a funny looking dog. Unfortunately, my 55 and 30 gallon tanks aren't big enough for one I want to know if this behavior is normal.
