Aquarium Fish Deformities

Most deformities are caused by one or more faulty genes. In the wild these handicap the fish in question, so it either starves or gets eaten long before it has a chance to breed. But under aquarium conditions handicapped fish are given all the food they need and are kept secure from predators, making it much more likely they’ll survive to sexual maturity. This is why deformed fish are so much more common in ponds and aquaria than they are in the wild.

Wise aquarists will ensure that deformed fish don’t breed by either removing them from their own kind or else destroying any eggs or fry produced. Isolating deformed tetras, barbs,  danios and other egg-scatterers isn’t usually necessary because any eggs they produce in a community tank will probably be eaten very quickly. But egg-guarders (such as cichlids) and livebearers are often able to breed successfully under community tank conditions. Deformed specimens of such species are best isolated or, if that isn’t viable, destroyed humanely.

Q&A: My fish is swimming with its belly up and it is fat. How do i ...

This is called Dropsy. The Pine-coning you are seeing is because of the swelling/bloating. Dropsy is more of a symptom of an illness or disease rather than a disease itself. There is no documentation of a fish recovering from it at this stage. I would strongly suggest Euthanasia with Clove oil.

I suggest you immediately take this fish out and put it in a quarantine tank. Also, you may want to do double cleaning for the next week to get as much poo out of the gravel as possible. It can be contagious if other fish come in contact with it’s body or feces.

If you can’t euthanize, I would suggest to use 1/8 teaspoon of Epsom salts to every 5 gallons to help soothe the fish and ease the pressure of the bloating. Do NOT use any other type of salt because it will make it worse. If you really want to try to save it which is almost impossible, you can use Maracyn or Maracyn ii which contains a broad spectrum anti-biotic, Maracyn being for gram positive bacteria, and ii being for gram negative. There is no guarantee that they will help.

    Obviously there's no cure for old age, though it should be stated that elderly fish often remain surprisingly active even if they do look a little moth-eaten! Vets will normally euthanize fish using an overdose of an anesthetic called MS-222.
