Welcome BD :)
Well, i rap gently the sides of the bowl (I recieved today my new Dymax IQ3 acuarium!! YAY!, so hell get into h is new home soon) and i keep chasing him around, he hides behind his plant, and peeks about as i rap again and he just swims around. Also, my sister who is an odontologist gave me an old plastic mirror and i use that to exercise my beta, as it flares all up looking all tough and mean, heh. I read somewhere else about the mirror, used to exercise bettas for 5 minutes, twice a day.
I've had him for a couple of weeks now, i've never had fish before, so when i got him as a gift i was truly worried about being able to care for him, and here at Bettafish.com found a wealth of information and people with experience and knowledge. So don't be afraid to ask around if you have questions, you'll get help for sure.
