How to care for bettas

[Pleco]

I have a 29 gallon and all fish except the betta are in the 29 gallon.

I agree with Obsidian. Just for future reference: the reason why Obsidian says to not listen to Betta man is because Betta man thinks that he knows everything there is to know about bettas. Betta man is a kid and he has had more problems with his bettas than anyone on this forum.

There are some forum members in India who don't need heaters, but most of us do. I only heat some tanks 8 months of the year, because my basement is 80 F in the summer. But having a heater is preferable to not. Need is a relative term. Can you possible do without X, usually there is a way. Is it more work than having X, almost always. Stuff is standard equipment because it works.
