I think it is too small. The minimum recommended is a 20 long, not just because of the bioload, but because of the footprint. I think a 15 is 24 inches (maybe?), but a 20 is 30 inches. Six inch difference is a lot of extra swim space.

If you have a fancy goldie in a 20, that's all you would have (bioload)

I thought the rule of thumb was 10 gallons per fancy and 20 gallons per singe tail, and then 10 gallons per additional fish?

Nope, 20 gallons for the first fancy, then 10 gallons for each extra.

For non-fancy, some people say 30 minimum for one, but I've seen people on here say that even 40 isn't big enough for the entire life, and eventually they will still have to go into a pond.

IMO a 29 is the minimum for a fancy. Even a 29 is tight when the fish is full grown.

12+ inches without the tail. And that's just their length, it says nothing for their girth and these guys get to be pretty round. Just to give you an idea....

The 20g long is 24"L I think it's 24"12"16" maybe.

A good way to tell if a tank will be big enough for the adult goldfish - take a 12 inch ruler and swim it around the tank. If it bumps into anything - the walls, the decorations, anything - then that tank is not big enough. Fancy goldfish can grow anywhere from 10 inches to 2 feet long. I believe the fantails are on the smaller end and grow to the 10 inch to 16 inch range. Also keep in mind that they are almost as tall and wide as they are long. Another good way to check size would be to use a volleyball, soccer ball, or basket ball to represent the adult fish. See how it moves and looks in the tank. In my opinion, a 29 (or 30) gallon tank would be the smallest for any fancy goldie. I have a 40 gallon breeder tank (longer and wider than deep) and I would not use it for single tail goldfish at all. They would not have swimming room. It would, however, comfortably hold one or two fantails - but that would be it.

Does anyone have pictures of these 12" fancies? I thought commons hit 12"+ and fancies were smaller.

Take a look at my thread [Gremlin's pond - again] and at the photos in my profile. You can see my goldfish. The majority of the larger ones started out as 'feeder' goldfish from WalMart and PetsMart. They are common/comet and some shubunkins. A nice little mix. Oh, and by the way, my sister has a pond also and her goldfish are about twice the size of mine. Since mine are about the 8 - 12 inch range you can imagine hers. I need to sneak over there with a 10 gallon tank and my camera and a net to get some pictures of hers. Some day...

Commons/comets and that type I understand hitting a foot. But fantails, moors, oranda etc I haven't seen any that big.

In my opinion, commons and comets need to be in ponds so they have room to swim. Once they reach the 6-8 inch length, they really don't fit well in tanks. Are you sure that the new comet is a female? She may have something wrong if her stomach is bigger on just one side. That is not normal. Do you have pictures of all three of your goldies? As for the injuries, Melafix is a good all around medication for goldie injuries. That and nice clean water. If you can get fairly good side view pictures of all three of your goldies, I might be able to confirm male/female. If the new one is a male, and Sid is a male, then they may be fighting over territory and/or the female. A bit more information would be helpful...tank size, pictures, water readings...
