I've been keeping a pair of Eclipse 3 gallon tanks for over a year for tossing in the occasional gravid ghost shrimp. I have sponge filters over the filter inlets, and they're covered with pantyhose to keep the newly hatched shrimp safe. No substrate.
My observations:
1.) Plants: I just keep Java Moss in them, and it grows like a champ when the shrimp are in there, and I'm doing small daily feedings. When I remove the juvenile shrimp to a bigger tank (after they've grown a bit), the Java Moss remains static (no extra food input).
2.) Temperature: Hard to control in this small of a tank with a sealed hood and light system (it gets a bit warm, can't get it below 82F).
3.) Stability: The plants help a lot. If I'm doing feeding (introducing nutrients into the water column indirectly through waste production by the occupants), I end up having to trim back the Java Moss regularly. This is good for nitrate control.
As I've learned from everybody else on this forum, you work harder to maintain stability of water parameters due to the small size of these tanks . I'd still get a 10-gallon kit from Wal-Mart for that Betta. That's where my son's Betta lives.
