Hey Atomweaver,

I can fill you in on the few things I know. It's a one-gallon tank
that does have an air pump and bubble stone. It is not heated, just
goes by room temperature which is usually around 78 degrees. I don't
know the water conditions, but I do change out half the water in his
tank once a week. I use the big 5-gallon drinking water jugs as my
water source and don't condition the water at all. He is all alone in
the tank. I got him full-grown at a Petsmart back in March of '06. Up
until recently, he's seemed very happy and healthy, but recently he
seems to sit quietly at the bottom of the tank. There are no other
signs of ill health (Ick, torn fins, etc.) Any input is
appreciated.

What size tank?
(ideally, he should have 5 gallons, or more)
Tank temperature?
(ideally, he should be in heated 79-82 deg F water)
Tank water conditions; ammonia/nitrite/nitrate/pH?
(ideally, they should be 0/0/20 ppm or less/6.8 to 7.2)
How frequently do you do water changes?
(ideally, 20-30% weekly or more)
Any tankmates?
(something that likes the higher temepratures, like a few cardinal tetra
would be good, as would a planted tank, or floating plants)
Did you get him as a juvenile, or do you otherwise know how old he is?
(Bettas kept in good conditions usually live 5-7 years, or more, but
you often don't know their age if they're bought full-grown from a pet
store...)
