1. Dont put to many in the tank since they can grow pretty large. And they poop a lot lol so this can get the water dirty pretty quick if you have to many
2. as many as you can pack in it!!!!!!!
3. Three is about right. I have three in my thirty gallon - they have lots of room but don't feel like there is room for more.
4. safe, rule of thumb is one inch of fish per gallon of water.
5. forget the 1 inch per gallon rule, it's BS you can fit comfortably 2 goldfish in there not more
6. i would say about 2 to 3. You dont need to worry about aggression but cleanliness and space are key factors. 2 to 3 is optimum but keep the tank clean get a charcoal filter.
7. 2 comfortably...3 would push the limits..but you can still go with 2-3 if you are on top of water changes..25% water change every week...they will be very happy and healthy...get a Power filter recommended for 10 times the capacity of 30 gallons...like Marineland Penguin 350...trust me goldies need it..:)
8. Three might be alright while they are small, but I would suggest going with two since you will have to figure out what to do with one once they get bigger and begin to produce more waste. You might be able to fit the three if you use a very powerful filter that is rated for at least double your tank size and if you did water changes twice a week, but that would likely stress the fish. So pretty much I say 3 is okay but 2 is definitely better. Good Luck!
9. 2 will be perfect. The rule for fancy goldfish is 20gal for one goldfish and 10gal for each additional goldfish.
10. If your tank is very heavily filtered, cycled thoroughly and you have a couple of air stones, you can have a maximum of 2. When dealing with goldfish, you must provide a bare minimum of 10 gallons of water per fish. Your 30 gallon tank will not hold 30 gallons of water because everything you put in your tank takes up space. Never take advice from anyone telling you it's ok to stock 1 fish per gallon, 1" inch of fish per gallon of water or any other such guidelines. Goldfish must have a lot of water as they produce enormous amounts of ammonia which must be diluted in large amounts of water. Also, fantail goldfish will grow to be 8-10 in length (not including the tail), and they will live well over 15 years with optimal care. Good Luck!=
