Ok, do you have them is separate containers/ bowls etc?


How often do you change their water?

do you have any stones or ornaments in the bowls with them?

Try the following.

Get some marbles for the bottom of their bowls.

Change their water every other day. Use tap water that has been allowed to sit for 24 hours. I bought a 1 gallon container of distilled water to start, and then refilled it from the tap.

Put the bowls close to each other so that they can see each other, watch their behavior. If they prance around showing displays of MALENESS, you're ok. If not then you got a problem.

The types of problems are fairly numerous, but since Bettas are fairly inexpensive it doesn't pay to take it to a vet. Look for signs of disease on the skin. There are several water treatments that can cure all sorts. If he seems to float a lot it could be an air sack/bladder problem. Reduce the amount of water in his bowl so that he can get to his food.

Bettas are raised in mud puddles that are rarely deeper than two inches -- so don't worry that he doesn't have enough water.
