Thank you Junne! I would love to have her happier in a shallower tank.Not sure on the 10 long but a betta would appreciate the shallower tank since they have a labyrinth organ, which allows them to breathe air. That's why you see them at the surface now and then to get a gulp of air.
Also as a side note, 20 longs are fairly common - ( Petco has the 1.00 per gallon sale ) and you could pick one of those up and divide the tank 2 or 3 ways to fit more fish in there
Right on-- I've been wanting to get her some water lettuce and floating hyacinth, but my current setup is too small.I was actually just at my LFS yesterday, and they had an 11 gallon "long" setup for a pair of wild bettas.
It looked to be about the size of a 20 long, but was just a few inches tall. Very interesting tank, although I think I'd just go with the 20 long and have some plants near the surface for the betta to lay on.
That sounds good-- she doesn't really like the plastic betta hammock, she seems to prefer live leaves.
