My fish, Oscar, got a nice 6 gal aquarium JUST FOR HIM!
It has:
Oscar ( My Betta XD )
Biological Filter ( Sponge )
Lights
Thermometer
A hood so he wont jump even though I never saw him trying to do that.
River rocks as gravel
Plastic/Silk plants and toys.

I think the filter is REALLY strong so I turn it on for 45 minutes everyday.
Oscar loves his new house. He swims ALL THE DAY ( YES, ALL, BELIEVE ME :D ) and sleeps/Rests during the night. His life is very good and he is a very lucky spoiled fish :D
