Wow that was a good thing you did. To think someone might do this to their pet I'm glad you saved them.

"Next time you feel small and insignificant, look at your betta, his whole world is on your table or whatnot. See how small his place is in such a big world? Now think of every time that fish has made you smile. If something as small as a betta can have that effect on a person, imagine what an effect you can have on the world."~ Olympia
Those goldfish aren't going to be able to stay in that tank for long. Common goldfish are active, messy, and large. Commons like yours regularly get over 6 inches and up to a foot long. You will need a 100 gal or larger tank to keep both of those fish. They are better suited for a pond rather than a tank. Your best bet is to find someone with a pond or build one yourself.
