. Right now i have my betta fish ( Beat ) in a fish bowl with press and seal on it, ( it has about 45 holes in it ) is that okay for now untill another week or so?
As long as there are holes and you change the water weekly - he will be fine
2. I dont know what type of bowl to get him. Please help! something under 15$ possibly. From wallmart.
http://www.walmart.com/ip/Hawkeye-1-...-Pets/10312983 is about $10. I would remove the filter/bubbles so there is more room. If you can spend a little more -I would go with something bigger. 1 gallon is a bit small and hard to heat up. Do you have a petco or petsmart? If so, go with one of the LARGE petkeepers. The ones in the reptile section with green lids are cheaper then the same thing in the fish section. The large is about 2.5 - 3 gallons which is a nice size for a betta. They should cost about $10-$12. Sometimes walmart has something similar - just make sure its at least 1 gallon, bigger if possible.

3. how much do i feed him?
How big are the pellets. His stomach is the size of his eye so I would do 2 pellets in the morning and 1 or 2 at night. I usually fast them on sunday.
4. i do i know for sure hes healthy?
Healthy bettas are active, their fins are not clamped, and they eat. if his fins start to clamp up or he only floats at the top of the tank or always lays on the bottom - someting is wrong.
5. At the bottom of the bowl i have little colourful rocks and a accesory does he
need more?
it depends on the fish - some do not like wide open spaces, others seem to be OK with it. The more hiding spaces there is, the less stressed the betta is. I like them to have a hiding spot like a cave, some silk or real plants and for some, I have floating plants. Some are live plants but for others I use tetra plastic plants because they float if not anchored to the bottom.
OOOH and at some point you should get a heater. You want 25 watts for a 2-5 gallon tank. They are tropical fish after all.
Do your parents have an ebay account? I got my heaters off ebay since the local selection is crappy. If you can find the HAGEN ELITE 25 watt heater, i suggest that one. Most heaters are pretty long and this one is shorter then most so it will fit into a smaller tank. Tetra also makes a small one but its not adjustible. I have a 50 watt one and it can barely heat 5 gallons above 72
