I've been trying to talk my dad into letting me build a 6x4x2 or a 6x3x2, and he was having trouble with some of the fish I came up with to stock it...We finally found a fish we agree on. Goldfish!!

I have a bunch of goldfish who were needing more space anyways, so this works out perfectly!! They get a nice big tank (269-359 gal) I get my nice big tank (lol) and my dad doesn't have to worry about his grandkids when they come over.

When my job picks back up, I'll be gathering my building materials. How many goldfish can be stocked comfortably in a tank that size? I currently a carefully mixed group of fantails, comets, and a single pearlscale, with 2 tiny corydoras (14 fish). I plan on adding more cories, definately, but I may only add one or two more goldfish, since I try to collect the odd colored fish (all/mostly white) I may try to get some gray comets, even though I don't have the best of luck with them... ><

I also want to decorate the inside of the tank to look like a pond, so you can see the fish from above, and from the side!! ^^
 
What are the sizes of the goldfish? It is generally recommended to not mix normal and short-bodied goldfish because the short-bodied ones are slower and have problems feeding. The long-bodied ones can be aggressive with the round-bodieds. If it is working so far then it is working, but I would keep a good eye on it or try to split them up if that is a possibility.

What temp are you keeping them at?
What type of cories?

I think twenty or so goldfish should be a nice school and they would do very well in there.
 
I think I got lucky with mine. All of our golds (except the 3 newest members) were purchased in similarly sized pairs. (usually 1 fan, and one comet)

My black moors, who I mantain are very pokey-poke (slow) are accepted, and left to their own devices!!

Even the pearlscale -who is the WORST swimmer in the world- is left alone!! The crazy comets even slow down when they swim past her!! When the fans swim by her, they don't, and it flips her over, but if she wiggles her tail too fast, it has that effect on her!!

My fiance has the 2 biggest fish in our tank (pool comet and r/w fantail), and the male (a 7-8" pool comet) is so gentle that he doesn't even bother the smallest fish (a 1" fantail)

Here's a pic of my horde at dinner time, sorry if it looks bad, the walls are green (which reflects off of the tank) and the flakes cloud my water (never let a laymen do a fishkeepers job!! lol)

Oh, I forgot, my cories are Pandas (I think) I don't have any clear pics of them....yet
 
I would feed pellets. They are much cleaner and usually higher quality. I highly suggest looking into New Life Spectrum, it really is the best thing out there.
 
Yea, we were thinking about pellets.....they just sink too fast, and my fish prefer eating off of the surface.

Then again, they are also very good bottom feeders...

In addition to the flakes, I also feed F/D baby shrimp, which I find to bring out the colors in my fish. The moor are rich black, the whites are white and not pink, and as you can see, the oranges glow!! ^^ They also get veggies (frozen) from time to time, since I was told the pearlscale had some digestive issues (none since I've had her) and I know the veggies are good for them anyways ^^
 
NLS's site is really informative. Check it out. I get great colors with it. You can see some of my fish on my PhotoBucket page.
 
i'm a bit late on this, but i thought i'd add my .02.

it's important not to feed a floating food to goldfish, especially fancy types. they are prone to swimbladder issues and floating foods can trigger it, since they are eating off the surface and swallowing air in the process. i feed my goldfish Omega One sinking pellets - the best i've come across so far. the ingredients are top-notch, no ingredient splitting, no land-based meat, all fish protein. theyre slow-sinking, too. i highly recommend them.
 
i've heard conflicting reports on the floating fish food theories, usually that the swim bladder problems aren't cause so much by the air swallowed but because flake foods tend to be low in fiber and high in protein. either way the best food i've come across so far(in stores, haven't looked online) has been tetracolor sinking granules, both my comet and fantail variety(in separate tanks) love it so i don't use flakes although my goldies do get occasional spirulina flakes as a treat. as for stocking about 12 full sized ones would nicely fill the tank.
