Hello Weeman, welcome to the site.
I agree with the others on here. You really need to get the cycling done first before you add any fish. Seeing as you have the ability to do a fishless cycle on the tank you really should take advantage of that. If you absolutley have to add fish to cycle the tank, then do not use golfish. Especially feeder goldfish. They can be notorious disease carriers at times.
Your far better off picking some hardy fish to start the cycle that you like & want to keep & get a bottle of Tetra Safe Start to use as well. (Remembered this time Ken

)
Whoever told you that you need a certain number of fish to cycle the tank obviously doesn't know any better. Adding X-number of fish will only cycle the tank to the
bio-load of wastes that those fish produce. If you then added more fish the tank would start doing a mini cycle all over again. If you were to lessen the bio-load by having less fish, then some of the bacteria would die off.
Better off doing a fishless cycle. There's some very useful info in the link that Ken has provided to you there that should help you along the way.
