Tynk,

One more question. Is it extremely necessary to clean/vacum the
gravel often?. Even if I have a large tank? Isn't the biologycal
filter enough to decompose and get rid of the food and fish waste?

thanks

So you have been keeping your betta for two year without filter, Then
I am assuming you change 25% to 50% of the water every week. Is that
right?

Aren't you supposed to do that regardless??

Hi Jen.
Are you asking aren't you supposed to do the water changes (yes) or
keep a Betta without a filter (it's always better to filter their
tanks).
