yup u were rite..is that an efficent size for 2 goldfish?? also how can u tell if ones a female and male??i noe annoyin much lol

I'd dare to say, yes, it's big enough for two, but there are several peeps here that would beg to differ and say that you should have a 40 gallon for two goldfish. So I think that's... a matter of your own measurement! I use this rule of thumb: about 1cm fish needs 1 liter of water. And since normal fantails (that's what you're having?) Are getting about 10 cm each, your tank is enough.
But then there are those who say that each mature fish needs 20 gallons. Which might be true for the bigger goldfish varieties. It's up to you (:

Determining the gender of goldfish is very difficult, and there are several methods described in books and goldfish sites! The easiest and most certain one is to wait 'til they are mature and will start spawning. The female will get rounder as she gets filled with eggs, and the male will start chasing her to encourage her to lay her eggs (can sometimes look aggressive). The male should develop white spots allover his gill covers and possibly fins, they should be rough to the touch, like sandpaper!
But then I've also heard that there are differences in pectoral fins (The front fins by the gills), males have bigger and females have smaller, but I'm not too sure about that yet d: And I also heard that males are longer with thinner body. And... then there's the differences in their anal openings, it's rounder on females.

Goldfish have a tendency to act hungry all the time! And they would easily eat until they explode, so therefore, it's better if you control the amount you feed them! Just feed them an amount they'd manage to finish in two minutes.
I suggest that you decide for certain feeding times! I use to feed my fish at 9 in the morning with pellets (Hikari Goldfish Staple), and around 4 in the after noon with blood worms twice a week, or a different kind of pellets (Hikari Goldfish Gold) and final feeding is at 10 in the evening with another dose of staple pellets I feed them this often since they are small fish and growing. The protein in blood worms is important for young, growing fish (: (But tubifex should work just as well!)
Don't forget to give them some vegetables! Like cucumber, lettuce or peeled peas occasionally, it'll clear out their digestive system (:

Anytime! (: I'm glad I could help!

I would hazard a guess that your smaller fish has dropsy. your bigger fish... do the white spots look like grains of salt?

Both your fish are sick with for sure a bacteria infection and the bigger one, probably a fungal infection as well.
You can treat both with aquarium salt, 1 TBS per 5 gallons of water, but I would do a 50% water change in your tank as well.  What size tank do you have?...Filtration?..check your water chemistry as well.
You can treat with melafix and pimafix according to bottle directions.  Melafix is for bacterial infections and pimafix is for fungus.  You can use both at the same time.

I'm guessing here that your fish is suffering from a water quality problem.  Have you checked the ammonia and nitrite levels?  It almost looks like a burn from maybe too high ammonia levels?
What size is the tank you keep your fish in?
Do you have any filtration?
How about extra aeration?
You first need to check your water chemistry and do a water change if necessary then add 1 TBS of aquarium salt per every 5 gallons OR 1 tsp of salt per gallon.  Add a bit extra water conditioner and I would also add melafix which is soothing on wounds etc.

My fishie has a Purple bubbly spot on her nose. What is it? Is my fish okay?  

Awww...I'm so sorry your fish died! :'(
I know I would feel very sad if one of my fish died.  You are right!  Some people just don't get it.  But fish are our choice of pet just like someone else might prefer a dog or cat or hamster.  And goldfish can live longer than a cat or dog too!
Maybe sometime after a while you might want to get a new goldfish.
I've had goldfish since I was 4 years old and never have been without at least one.

It's not very good, no... check if you can see any spots on him, or if his fins are clamped or torn! Is he eating well? It could be good asking your dad about that if you're not feeding him yourself...

its weird tho because he swims, and its not like hes just sitting on the bottom he swims, but in the corner, and every now and then he goes exploring around the tank haha. it seems like hes just attached to that corner? haha.
but every time i put new water in i put in water conditioner.  been doing that since i got them.
ill have to get a kit to test the water.
any suggestions on what kind to get or anything?
thanks.

hi

don't know if i am typing in the right place, I have 1 goldfish in a tank of 6 and 2 suckies as the family call them They have all swam happily for over 1 year, now 1 has got very fat, it's eyes are bulging and it's scales are starting to look different. At first we thought eggs maybe on the way but with her eyes popping out we are now not sure. Can anyone help me with an answer? PLEASE
Many thanks
Tracy

The bulging eyes have been discussed before (how to treat: (Link is not visible to guests. Please register to view.) ), but it might be that if she got "fat" and her scales changed (as if she looks like a pine cone), she could have dropsy. For which there currently is no treatment.

I have brand new gold fish very little and I don't know how much to feed them?? Can you help me please??

Goldies also like well-rinsed lettuce leaves and nibbling on live plants.  Does your tank have live plants for the fishies to swim through and hide in?   They enjoy those a lot.

plain frozen peas, thawed, shelled and cut into tiny pieces, so they can eat them
