It's nice, but maybe you should read up a little bit on goldfish care. They are really messy guys and need a bigger tank than five gallons. 5 really isn't even big enough for 1. I am not trying to be rude, but I would hate for your fish to get ill and you lose them because they are in too small quarters.
Here are a few links
Areil That's a nice tank..but Cajunmom is right ..Goldfish are messy, get big and require alot of space...maybe you should have got some small tetras..or Hi-fin Danios..they stay fairly small..be carful with tetras..some ( like the Buenous aries) get BIG
