Goldfish is swollen around the stomach and turning black?

Answer 1

Gold fish turn black because of exposure to ammonia. This is common in pet store gold fish, because they are kept in crowded fish tanks that are not maintained very well. The black color is like a scab healing over the damaged areas of the gold fish.

Answer 2

Erratic swimming, bloating or swelling in body, black patches on body or fins. Myxobacteriosis -- rare Medications, if any, are difficult to come by. Keep up on water maintenance to prevent it.

Answer 3

If a goldfish's skin is burned, irritated, or damaged somehow their bodies will produce a chemical called Leukine. Leukine stimulates cells so that the damage is repaired faster. The thing is Leukine especially stimulates melanophores (black pigmentation cells) and they begin to reproduce rapidly in that area. This is why the goldfish is turning black.

Answer 4

If the fishes scales are sticking out and look a bit like a rasp or file then your fish sounds like it has dropsey and is terminally ill. If on the other hand the scales are sitting down smoothly as per normal then it is possible at this time of year that the fish is female and is ready to spawn if a male goldfish comes along. If that is the case, after a few weeks the chubbyness will go away as the ova are re absorbed into the fish and it will return to looking normal. The reason why your goldfish has a red belly and is looking bloated is because it is sick with an internal bacterial infection caused by aeromonas. This is treatable if you catch it early enough. The bacteria causes the fish to look red on its belly and has ultimately caused organ failure which explains the build-up of fluids that are causing it to look fatter than normal. Although its probably too late if the fish is looking bloated the best thing to do with a fish that has a red belly is to take it to a piscine vet and have then give the poor thing some anitbacterial injections(or any fish exposed to the fish). The next best thing is to feed the affected fish some medicated antibiotic food.

Answer 5

The black appears when tissue is healing after being severely burned by ammonia, seeing this pretty much means you need to stop being so careless with your fish and do more major water changes.

Answer 6

The skin on the fins was irritated somehow. When this occurs, the fish's body releases a chemical called Leukine to stimulate cells thus repairing the damage. In some cases, however, the melanophores (cell responsible for black pigmentation) are especially stimulated by this chemical which causes an abnormally high amount of black pigmentation on your fish's fins. After awhile the melanophores will eventually recede and your fish's fins color will return to normal.

Answer 7

It is probably ick and you need to treat it quickly.

All there doing is growing thats all that just means he growing to an auldt
