First of all, for 6 goldfish, you'll need a minimum of 60 gallons, preferably larger, especially if you're talking about single-tailed goldfish. Just making sure you are aware of this

I have a plain colored blue background in my tank, it really bring out their colors, even the white ones glow BUT, the light is as important as the background. I have a bulb that enhances reds, blues and whites, so try looking for something like that.

Yellow goldfish are also very rare, and can usually only be bought from breeders, but there's nothing wrong with planning, of course

Switchkick- welcome! I made a very simple background today in about 10 minutes by glueing slightly crumpled tissue paper in shades of blue to two large posterboards then lightly dusted it with silver glitter. It only cost $4.00 to make 5' X 2' and the effect is quite pleasing. In my opinion the photo-backgrounds look tacky. Blue and black are nice but can be a bit pricey (especially if you have a large tank for those six goldies)

Thank you for your answers!

Will probably go with a black background and dont worry, the aquarium is big enough. Its a 260 liter tank to keep them in while they are young and I have plans to upgrade to a larger tank aswell in the future.

Had no idea about the yellow ones, seen them just about everywhere around here! A shame if they dont stay yellow.

Been thinking about getting a fluval 405 or maybe even a fx5. Not sure yet, dont want a tornado in the tank either

I live in Sweden.

Ei saa peittää! only finnish I know

Might get to pricey it seems. The Fx5 from fluval is for aquariums up to 1500 liters so I´m pretty sure that would work but its expensive and people say its noisy. Tank is in living room

Anyhow the background will be black, going to buy some slimline or something and do something nice with it.

Switchkick: Ha! I speak fluent Swedish, and prefer using that before Finnish anyway
Have a look at the link Skwishee added, that's just the filter I mentioned, and it would be great for your tank!

Skwishee: Pretty many goldfish change color, especially the two-colored ones (red-black for instance). It's a bit of a shame though
And that's JUST the filter I was talking about! I'm so getting one asap D':

Happy new year!

Switchkick, I was wondering what you finally decided on what to use for the background. I see that you said it would be black, good choice. Black works well for several reasons.

I have a recommendation if you haven't done it yet.

Sprays on like spray paint, dries like rubber coating. This stuff is awesome. Tape up the tank, spray a few coats on the outside of the back glass and peel the masking tape off. Let it dry and set up your tank.

It dries like a rubber coating and can be easily peeled off if you decide to remove it.
You can see this guy peeling it off of a car emblem.

It can also be used to make wood grain rims black.

The stuff has a lot of uses. We also use it in the R/C hobby to waterproof stuff.

I painted tbe back of my big tank with black latex. I didn'tknow about this stuff back then.
