They are scared. esecially whenthey move into a new tank.
I have never seen any Betta fish's go crazy, but, it is possible.
keeping multiple bettas in the same tank is not reccomended
None are recommended if the Betta is a male.
Go to petsmart and ask a person there to show you witch is best for your baby betta fish.
Y-E-S they can! Go to youtube and type betta fish doing tricks.
No they cannot, also if you put two Betta fish together, they will fight.
Go fish
Betta dish actually don't sleep, or they'd die.
they have a shelf at wal-mart that is like animals and if u go to the begging of the aisle there it is and make sure it says betta fish food
none unless you want to be super cruel
Yes.
Just go to the vet for a check up.
