Today I learned some things about betta fish from looking first at the Pet General thread and then at Wikipedia...

-they are VERY colorful;
-males make nests of bubbles to give a female a place to lay eggs;
-only one male betta per aquarium because the guys don't get along with each other;
-did I mention they are extremely colorful?

But, Betta people, what do you do with those bubbles when you have to clean the bowl? Do you just dump it? Does the fish get confused about where it went?
