I havent seen them any bigger in body length though ive heard 8 inches can be achieved.

So could I have 3 Celestials and 1 Bubble Eye in a 30g? It would be okay with the inch per gallon rule and I could buy good filtration systems. I know the rule of thumb is 20g for the 1st fish and 10g for each additional fish, but that's for common goldfish, is it not?

its 30g min for commons, 20g then 10g for each other fish for fancies. You could have 2 in a 30g

The rule you mentioned is for fancies not the common goldfish. You have three choices to keep your fish happy:
1. Keep 2 of the goldfish in that tank and give the other 2 away.
2. Upgrade to a bigger tank to keep all 4 of them in.
3. Get another tank the same size and keep 2 in the tank you already have and put the other 2 in the new tank.

You will need good filtration systems no matter what as goldfish produce alot of waste compared to other fish.

I would not put more than two fancy goldfish in a 30g; the waste output is the issue more than the size, and even with good filtration it may be hard to maintain adequate water quality. Goldfish are also quite active and enjoy plenty of swimming room, so two 6-8" fish in a 30g is really the max you could get while still maintaining a good quality of life for them.

As for commons, since it came up... Common and other single-tail goldfish should not be kept in anything but a pond at maturity; they have the potential to reach 24" in length, and unless stunted will undoubtedly reach at least 1ft. The 20g per goldfish rule, thus, does not apply to them - unless you want a fish whose tail sticks out of the lid for him to fit! From what I've heard, you need anywhere from 3-5 gallons per inch for commons, so the minimum tank size for one mature common given the growth potential, imho, is 75g. Obviously they can be grown out in smaller, but because they are a social species, they are best off in ponds upon reaching any reasonable size.
I personally can attest to how insufficient aquariums are for commons; I have two three-year-old commons myself. They are each about 9-10" in length and seem to grow every day, and live together in a 75g. Even with massive over filtration (think about 10x's what you'd need for two tropicals of that size in the same tank), I am searching for a cheap pond so they can each have a good 150g per fish.

Okay, thanksa lot. In that case I think I will get two celestials. Do you think they will be lonely?

 

[RandomWiktor]

I doubt it; goldfish seem to do well enough in pairs, and don't appear to become lonely unless kept alone. I have a special needs goldfish fry right now who has to be kept apart from his spawn siblings because he is so undersized. I feel awful about it, because all he does is pace! But his parents live together in a pair and get along fine, so I think you'll be good with two.

Ok, I have another question. What about a 55g? With the rule of thumb I could have.... 4 and a half goldfish. So is that 4 or 5? I would want celestials and bubble eyes.

And do celestials require specialized tanks like bubble eyes (no sharp objects)
