A: A sponge filter is the simplest and easiest kind to use, and are ideal for tanks with betta. It’s an internal filter, simply made of a sponge-like material with an air pump used to push air bubbles up through the middle, drawing water through the sponge and allowing the bacteria to do its job.
Q: Does a Betta have to have a filter?

Q: Does my Betta need a filter?
A: Betta fish do need a filter, to help supply the oxygen they need to breathe. Ok, such a simple answer is a gross oversimplification of the subject. Let’s try again with more detail.

Q: Can a betta fish can live with no filter?
A: Yes, a betta fish can live without a filter but that doesn’t mean that they’ll be completely fine. Before you make sense of that, note that you’d hardly find a fish in nature that can survive for longer periods in water that has not been naturally filtered.
