Good solo fish or pair for 56g?

thanks starsapphire, found plenty of pics of goldfish tank on google, they just all look kinda blah to me, not sure how to no a nice display tank with them.
 
This is my tank right now...it's a lot of hand me down decor from the previous owner, as I bought his entire setup off craigslist. As you can see it has a lot of holes. This is fine when your fish are still small, in fact mine absolutely love playing in them! However, my tank will be going through a remodel in the next week or two, because I'm getting new fish next friday and they are a bit bigger than what I have and one of them has an issue swimming, so I need to take out the current decor, minus plants (I'm planning on getting one of those 2 or 3 piece ships, since the tank is in my nautical decorated living room) and I'll be adding a background as well. Especially as your fish get bigger, not only do you need to minimize holes, but make sure there's enough open space to swim. Also, for your substrate, if you do goldfish, you have to do sand or river rock, NO gravel. I personally prefer my sand, and the goldies love to dig in it. Here's my tank!

This isn't the exact shape of your tank and it's obviously photoshopped, but this is kind of a cool concept of something you could do with your tank that goldies would love! Just imagine it with goldie in it instead. I have fake sand-level plants like that and my fish love to dig in them for food. they'd love to play in the driftwood and other plants and the sand is available to dig in.

There really are no right or wrong ways to do a goldie tank other than things that are just dangerous. FInd a piece of driftwood or a decoration that you like and build your tank around that. Make it how you want it to be.

right now the idea of have in my head is mostly rock, full rock background, some low laying grassy plants and some sort of center feature thou im not sure what i thought about rock formation or single larger plant or maybe driftwood but i dont think so. with all the equipment hidden. right now im just in the plumbing phase and making the support for the background.

im going back and forth between goldfish and severums both are suppose to be very personable.
 
My goldies are very friendly and they love having goldie friends. I don't know much about severums so I can't halp you there. A think maybe a single larger plant in the middle with a couple smaller rocks around/near it would be very cool. I think a rock formation with a rock background would look boring and kinda cold I guess, you know? Or driftwood with smaller plants around it. For filtration, I'd recommend the AC110 for your tank if you do goldies. You can customize media in that one. Or a canister if you prefer (I personally just don't have the space for canisters, so I can't make a recommendation on that one). Sponge filters are awesome as an extra filter too, goldies need high oxygen, and that extra surface movement will help, plus help break down all the ammonia they make. Good luck! Can't wait to hear what you decide and see it when it's done!
 
filters already taken care of, have a nexx filter with 2 additional units, bought it all new off craigslist for $75, very nice setup, medias kinda expensive but you dont have to rip the canister apart to replace it, and with extra units you dont need to replace it all at once, plus theres no internal pump to burn out, its a seperate unit that can be replace, im tossing the orignal submersiable pump for a external eheim unit so all i need to hide in the tank is the plumbing which is getting hard lined in with some prefilters for instakes.

im leaning towards the large plant as well. i have a very large fake amazon sword that im going to try(think its around 15" high and about 12" round) i agree more stone would probably be too much, but with the natural supply around here i can play with the idea cost free.

will def post pics of the progress, i dont expect fish until the fall thou.
 
i say cichlids :) why not go with some malawis ( there are colorful species ) or tangs? maybe a trio of peacocks or haps? if haps, go with either 1 male 3 female elec blue ahli haps or 1 male 3 female zebra obliques :) i love my two females ( elec blue ahli and zebra oblique ) trying to get a male for those two. or get some peacocks ( i have eureka reds ) 1 male 4 females or if malawis, go with yellow labs ( 6 ) and one other specie that doesnt get more then 6 to 8 inches..... or tangs, go with shellies or rock dwellers ( i have multies, which are shell dwellers ) and get some julidocromis which are rock dwellers :) 6 of each :)

I don't know if that would be a good idea in a column tank...you really should do like half stocking in columns with the dimensions, IMO, unless you're doing little fish. Big fish like that just won't have enough room otherwise.
 
in this tank, should be fine.

OP. or do some groumies :) they are also fun! with some corydoras for the bottom.
