And most importantly you must feed the fish. I have seen too many people that have believed that a betta can live off the roots of the plant.
Nothing can be farther from the truth.
The betta needs to be fed every day . Not every other day, once a week, and NOT once a month. 1 Notice the lines on the betta, he is stressed. The main thing you have to remember is feed the fish, change the water, de-chlorinate the water, and make sure the betta can get air . Go to my links page and see how other betta people keep their bettas, and what they have to say about The Peaceful Pair craze.
