Answer 1

you will also need a filter, and are your plants real or fake? Goldfish like to nip or even eat on live plants which can cause disruption in the plant's growth cycle. Remember to keep that water cold too, since goldfish won't tolerate hot waters!

Answer 2

you can have only 1 single goldfish in a 20 gallon tank, as that's the main rule to start with

20+ gallon for every first goldfish

and an additional 10+ gallon for every further goldfish you want to add

just make sure you get some decorations where he can hide in

and definitely make sure you get at least a 30-40 gallon rated filter for your 20 gallon tank
