Like I said earlier though, I would never want a tank bigger than a 55gal, so maybe I should just stick with pet store fishies. What % of the water needs to be changed each time, and how do you do it? I know for my betta I just fill up the bucket with dirty water, dump it out, fill it with clean water, and add it to the tank. done. But even that bucket with 2-3 gallons of water in it is getting kinda close to my limit as far as weight I can carry, so I could PROBABLY carry a bucket with five gallons of water in it, but that's really pushing it, and that's only 10%!

Ideally, you don't want the goldfish to munch on your plants as you want them to grow and remove a lot of ammonia. I've found that slipping the plants in when they are young helps reduce their propensity to snack on them. Also adding large mature plants usually stops them.
For water changes, I do a 50% PWC weekly. I don't use buckets anymore as it gets rather backbreaking with my 4 aquariums. I use a
python water changer; it has been one of the best investments in fishkeeping I've ever made. You remove the water using the 25 ft hose and then replace it directly from the faucet. You add the decholrinator directly to the tank as it works instantly to remove the chlorine. I honestly cannot imagine maintaining my goldfish tank as I do without my python.
There isn't really a good way to tell just how large a goldfish will get that's why we give the range of between 6 and 10 inches. Some breeds have a tendency to get larger than others. Like telescopes and fantails usually get rather large because their bodies are longer than that of a ryukin or ranchu. Oranda also have a tendency to get big. Breeding, food, and environment all play a role in adult size. While we can control two of those, the third is our wild card. Who knows what kind of stock your or my pet store goldfish came from. So that's why we can really only give you an estimate.
