Goldies Got The New 55

Sooo, I decided to spoil my two fantails with the 55 I originally wanted cichlids in. They have just been introduced to their new home and all is well so far. I have a hang on filter from their previous tank which is rated for 70 gallons, and their new canister filter is coming Monday in the mail! Which will be used in addition to the old filter. My questions are as follows:

1. Two hoods will fit on here, what size?

2. I would like to add more goldfish, how many fancys? I don't have a quarantine tank either.

3. I bought a sponge filter but don't know how to hook it up to the air pump?

 

I would do 3 fancies maximum. 20 Gallons per fancy is a good rule.

 

Two 24" hoods. (Same hood as a 20T)

 

You could do 4, or possibly 5 total according to this thread: How many Fancy Goldfish in a 55 Gallon Tank?

 

Rabbit trail: dang that's a good looking stand.

Back on track: From what I've read, 20 gallon per fancy, 10 gallon per fish after that. But lots of filtration anyways.
