The difference between dropsy and a goldfish being pregnant is that dropsy is a fatal condition caused by poor living conditions or an internal bacterial infection. This usually results in the body filling with fluid thus causing the fish to appear bloated. When goldfish get ready to spawn a female may appear slightly bloated or thick-bodied in accompaniment of the eggs in her abdomen. Goldfish use external fertilization to reproduce so therefore a pregnant goldfish is impossible.
In general, if the fish is acting rather sluggish and is staying at the bottom, or if they start looking like a pine cone, (raised scales) it is probably dropsy.
Huh? Come again? As far as I know, (sorry,) Goldfishes do not, um, become pregnant. Instead, they lay eggs. Your goldfish is most probably either down with dropsy (touch wood, okay? There is no cure for dropsy) or laden with eggs.
The goldfish will stay at the bottom, barely able to move, and will appear bloated. In the final stages of dropsy the fish's scales will stick up and the fish will resemble something that resembles a pine cone.
That is what Ryunkin Goldfish look like. If however, the fishes scales are sticking out like a file or rasp, the fish is suffering from a fatal disease called Dropsy. There is no known reliable cure for Dropsy. There are expensive medications available at pet shops that make the claim to cure Dropsy but in my experience they do not work.
Your Goldfish is not pregnant it has a deadly disease called 'Dropsy'. So the prognosis is very bad. This disease is usually caused by the fish being kept in poor water conditions. There is no known, reliable cure for this disease the fish will die.
In dropsy the scales stick out from the body like a wood rasp. If your female molly has been in a tank where there is a male molly present then it is almost certain that she is gravid (pregnant).
When a goldfish becomes bloated in appearance and all the scales start sticking up then the fish has dropsy, a terminal condition. Dropsy is the result of a build-up of fluids caused by organ failure. The reason for the symptoms of dropsy is either an internal bacterial infection or poor water quality. By the time the fish starts to have raised scales there's nothing else you can do for it - so don't waste your time or money on the types of medications you add to the water that say they "cure" dropsy-they'll only burn the fishes gills and make its last few days on earth even more miserable.
Don't get your hopes, high, because goldfishes DO NOT, umm... become pregnant. Most probably, it might have a case of dropsy. Quarantine it immediately (I don't know if dropsy is infectious, but don't risk it.) and examine it closely. If its scales are protruding, the fish is doomed. If there is no signs of anything like that, relax. It is most probably ... carrying eggs? and there is no disease infecting it.
It might be dropsy and this disease is deadly. I hope your fish heals. You should consult a local doctor though.
Dropsy Serious and difficult to cure, the fish's body can become so bloated that the scales protrude. It would just be at the bottom of the fishtank or pond and it would look like santa that has ate too many pies and he is sleeping on a bed with his eyes open
To my knowedge there is no proven cure for dropsy. Some pet shops carry medications that 'claim' to cure almost every disease and problem including dropsy but I have never heard of them working successfully on dropsy. I would euthanase the fish.
Dropsy is the former name for oedema
Most types of fish can get dropsy, although in my experience, it is more common in live bearers and tetras.
