Awww....That sounds kind of sad. Especially since Mandarins really just mind their own business.

I've seen some weird animal pairs out of water. ex. A feral cat use to follow my horse around everywhere and they would share food. That being said I guess fish with fish shouldn't be so weird.

As I've been watching it looks like the Tang has taken on a "you hide, I hide" mentality. He also did this at the store but that was with another Hippo Tang. Its double funny when the Royal Gramma just disappears without warning. The tang hangs there for a minute like "Hello? Uh....oh crap! Hide!"
