goldfish and loaches

[Phoenixphire55]

So I want to have a 50 - 60 gallon tank with several goldfish in it sometime in the not so distant future. I'm trying to think of how I'd do the tank as far as plants? tankmates? etc. I'd like it to be a pretty cool looking tank because I want the goldfish to add to how sweet the tank is, not be the only thing to look at. However, I know the amount of waste goldfish produce causes some limitations. With those in mind I'm trying to figure out what plants could be in a goldfish tank without being eaten. The plants would be for ornamental purposes, not there to oxygenate the water or for spawning, so I wouldn't need a bunch of plants. I was thinking of putting some in pots. Also, tankmates. I think the idea of having a school of corys in the tank would be awesome. Any other ideas for goldfish tankmates?
