If your goldfish is lying on its side at the top of your tank, or floating with its tail up, it probably has fish's bladder. to fix this you should try feeding your fish mashed up green peas (i know it sounds gross but it works) for a couple days instead of its regular fish food. also take a look at its fins. if they look shredded or inflamed, and you have other fish in the tank, TAKE THEM OUT IMMEDIATELY! they might be attacking your sick fish. when you transfer your other fish, be sure to put them in a tank or bowl with a lid, or else they will jump out. this happened to me and i found my fish dried up and dead. if it is on the bottom of the tank, it probably has ich. get some water treatment drops, and test the nitrates level. Hope this helps! I've had goldfish for six years, they have died of every disease imaginable.

Fantail goldfish are a hardy breed, strong swimmers and they compete well for food with the ryukin, shubunkin, comet or common goldfish; making these goldfish breeds good tank mates for your fantail goldfish.

My fantail Goldfish has been alone in good size tank now for one year I put a common Goldfish into the tank just yesterday and the fantail seems to be 'bullying' the common Goldfish What is happening?

The fantail goldfish is asserting it's dominance over the common goldfish. The fantail goldfish has already established in its mind that the whole tank is its territory and will fight any other fish that try to change that. This is normal when adding new fish to an established tank and they will usually continue to fight for a couple more days. During this time make sure to give the fish plenty of food to eat and some place for the common goldfish to hide. If they do not stop fighting after several days than I would recommend moving the common goldfish to its own separate tank of at least 20 gallons. Another reason (though not as likely) is that the common goldfish is a female and the fantail is a male. A male may chase a females rear- this is normal but if he harrasses her- remove her immediately.

Can an oranda goldfish live in same tank with regular goldfish?

Yes, but your tank size needs to support it. If you mean that a regular goldfish is a long single-tail goldfish, then you need at least a 40 gallon tank just for the 2 fish due to the size potential of the common goldfish. If you mean a regular goldfish as in a round bodied fantail, or perhaps a ryukin, then you need at least a 30 gallon tank for the 2 fish.

Do you need to separate sick goldfish from healthy goldfish?

Depending on what your sick goldfish has, it will either be specific to that fish, which you should place in a separate tank to treat, or it's something that will spread to other fish in your tank, in which case you will need to treat them all.

You have a fantail goldfish and it has been alone in a tank for 6 weeks you added another fantail today and the new one is attacking the old one Is this normal?

The only time I know of when goldfish become territorial and attack other fish is when they are overcrowded and are struggling for life itself. Is your tank big enough for 2 goldfish? The basic rule/calculation for keeping fish is "1 inch of fish needs a minimum of 1 gallon of water". A goldfish commonly grows to 10 inches or more so the minimum sized tank you NEED for 2 goldfish is a (Nominal) 25 gallon tank in order to have an (Actual) 20 gallons of water.
