Why did my betta die suddenly?

But how do you know you have all the species?

I"m sure that we are all open to new concepts, and seemingly not what we have been told... but yes you can successfuly cycle a one or less gal tank. The bacteria is only limited by the media surface areas and the o2 exchange and food..so if you provide a type of media that has a vast amount of areas for the bb to grow in and on and provide the required surface air/gas exchange and don't exceed the bio load... I'ts all a matter of balances. I don't advocate the use of drinking glass as fish tank...ever... the nerd in me has spoken, I am skulking back to my dark little corner now...that is all.

I agree with 1 gal cycle but I disagree with less.
