The "dragon scales" are very cute. They're basically just what Petsmart calls their half-moon plakats. I still remember my first HMPK, and I've been partial to them ever since. In my opinion they seem more active and responsive, and I've heard they're supposedly more closely related to wild betta. Oh, and the food ritual? That's a sign of a playful, smart, and creative fish. A very good thing. :)
Congrats on the upgrade! You may want to construct a cover for that though. Even a betta who isn't a regular jumper may have a hop one day. I learned that the hard way; a few years ago I came home to an empty tank. Never did find the fish, I think my dog probably discovered him... :(
Personally I really like the cubus. I know a lot of people would grumble at me about how small they are but Pei Ling is thrilled with his. I've just gotten back into fish after a long break of not having any, and my cat is very young and nosey, so I'm limited to places where I can put my tanks. Most of those locations won't put up with more than 10-20lbs on them. *sighs*
I originally had Pei Ling in the Fluval SPEC but honestly he didn't seem very pleased with it at all. One day I turned it off for a little bit and he started dancing all over and playing, happy as can be. I realized he didn't like the current of the SPEC. Stuck him in a cubus and he's just having a blast. Some betta like playing in bubblers and currents but this guy likes still water I guess.
...Good grief I'm rambling. *shuts up*
