Wow this is just like gold fish. They started out being in Betta sized bowls, now no one keeps them in tiny bowls. They progressively (over 5-10 years, sadly) Got better. I think that this is happening with Bettas, too. They're starting to sell larger tanks. Sure, the newer larger tanks aren't perfect yet, but they are improving. Those adds we get at the side of the website advertise a 1 gallon bowl with the colored dots all along the bottom. Before they would have been a half gallon or smaller, see things are getting better. Than this vase thing comes out. It has a heater and 1.5-2 gallons of space. ALRIGHT it's not the best, the size of 2.5+ gallons for more Betta activity levels and the water changes aren't described as frequent enough, but it is at least larger and with a heater.
Before it was goldfish. Now it is Bettas. The next to come will be the guppies.
Hmm, that looks exactly like the vase I got for 5 bucks at Wal-Mart, that I keep Blue Velvet. I have a cheap little heater in mine, so I wonder what that base heater thing, they are using, actually is.
