he is actually quite fond of my gsp! spot can be nowhere to be seen hiding in his cave and when you look in front of tank he rushes out and starts a wiggle dance..
Yes I know the wiggle dance very well. My bigger one (The Beast) even swims up and down with his lips right on the glass. When he goes down you can see his top tooth plain as day, when he goes up you can see the bottom one. The whole time he does this, his rear end is wigglin like crazy. It's so funny to watch.
