I want to know what else is good to get.

I reccomend TetraFin GoldMedal. The fish seem to like it.

BioBlend for Goldfish from Marineland are very good, nutritious and easy to digest. Havent had a floater from that food yet, and they come in convenient 5 lb buckets (well, what can I say, my fish go through a lot of food )

Hikari lionhead enhancer sinking pellets - those are great, they sink almost instantly, but still can be soaked without them falling apart. They also help greatly with wen development in hodded goldies.....
