I got 500 dollars and thats for the pond and the fish i wanna get
You will need at least over $2000 to fully set up the pond. If you've ever stocked up even a 10 gal you know how fast cost piles up. First you need to get the pond ($300), then the fish (let's say $150, though it would probably be more than that), then the substrate ($100), then the filter ($500), then the heater ($100), then maybe driftwood and decor ($300), then dechlorinator ($50), then a massive water changer ($200-300), $25 a week in food, possibly meds ($250)...it all adds up. Just the price of a good filter goes over your budget.
I appreciate the enthusiasm but please listen (tons of members have advised you to get some experience and start with a smaller tank, including some of the most experienced and knowledgeable people on here, and not unkindly may I add) to us and get a 50 gal or something. Even to set that up would be pushing your budget.
When I first got into fishkeeping at age 12, I was super dedicated and made an aquarium log of how the fish were behaving, how the tank was doing, etc. Looking back through that a few years ago, I was astounded to see that I had spend over $400 on maintaining the 10 gal in a year. That's a 10 gallon tank. I had a $100 budget to buy stuff and just managed to squeeze all the stuff I wanted to get in there. But maintaining a tank costs money, and the maintenance cost increases exponentially the bigger your tank is. $500 is not one-tenth of the cost you will spend on that tank in a year.
