That first tank is really nice! I like it a lot.
The Betta's living conditions don't seem happy though.

If one of your Betta have a less aggressive attitude maybe can go into the large community tank and the other can go in the large bowl- with additions of gravel and a plant? That'd be awesome and than you'd get comments on them too.
( but I really don't know much about the fish you have other than the Betta. So if they are fin nippers, nevermind. :S )
Again though, beautiful tank.
btw... what's covering that larger bowl?
