2 Fancies And A Short-finned Goldfish?

[GoldfishAttentionSpan]

I think I have heard that long finned goldies can't be kept with short-finned goldies, am I right?

double tailed goldies such as orandas and moors are slower than the slimmer single tailed fish such as comets and commons, and can bite at the tails of the slower fish. Its not recommended to put them together for that reason.

You technically can keep them together, though comets and commons are faster and more aggressive and will likely eat most of the food and bully the slower fish. Commons and comets are really best suited to being pond fish while the fancies are suitable for aquariums.

Ok, what kind of goldfish is this, and could s/he go in with 2 fantail goldfish?

I know s/he shouldn't be with the tropicals, espcially in a 5-gallon tank (its my quarantine tank), but this is a very temporary set-up. Its a long story, but there were 5 goldfish, 2 fruit loop tetras, and 2 longfin danios in a filthy 29 gallon tank. I'm trying to find them homes. (Florida, if anyone is interested.)

Looks like a common. As long as the fantails are close to the size of the common it shouldnt be a problem, but 2 fan vs 1 common, I dont see a problem at all. I have 3 commons, 1 comet, 1 fan tail, 3 red tailed tin foils, minnow and a pleco, and they all get along great. My fantail is a fat little slow poke, but in a 55gal he has plenty of time to eat. Black moores dont stand a chance with there telescope eyes. I tried twice with them, there eyes dont allow them to get there fast enough, even the fat little fantail was faster, but he has regular eyes. But my guys are somewhat the same size give or take 2-4"

From what I understand, the fantails are a goodly bit larger than the common at this point. From pics, the fantials look to be about as big as a tennis ball, without thier fins of course.

They will all be fine together then

Its not the size of the fish that matters its the type. Slim type goldfish like common goldfish (which is what you have) are faster and more agile than fancy goldfish, and although not typically agressive fish in nature, if you put them in with fish which are slow swimmers and can't defend themselves easily like fancy goldfish, they'll sometimes take advantage of the slower fish and pick on it. Its a bit like neon tetras and long finned male betta's- neon tetras are typically peaceful fish, but have been known to fin nip the long flowing fins of male bettas because male betta's simply have no defence against them etc.
So just be careful when stocking such fish with other fish and have a back up tank in case anything goes wrong where you can imediately move the victum or bully fish too- goldfish also have a reputation for eating any fish smaller enough to fit into their mouths which is too slow to get away and common goldfish are no exception, so i would also be careful about that.

Common goldfish can easily grow to over 10inches long, i have a common goldfish which is 8inches long and still growing with no signs of stopping, so many people opt to keep them in ponds as to keep one in an aquarium you need a very large tank (i would personally say a minimum of a 5ft long by 18inch wide tank due to their large growing size and high activity levels).
If you lived anywhere near Somerset in England i'd be more than willing to take the goldfish off your hands if you are looking to rehome it .

Well, you are actually one rather long plane trip across the pond, but I appreciate the offer anyway.

I told the potential owner what all of you have told me, and they would like to go ahead and try, and if issues arise, I will take the goldfish back.
