6 Common Fish Problems That Could Affect Your Pond

Lightbulb moments - ah so that's what that xxx is stuck on my fish!!!

We arm you with the knowledge and resources you need to identify the most common fish ailments and ensure an optimal living environment for your fish – from goldfish to Koi. Here they are – in no particular order.

fish bacteria

Bacterial Infection

If your fish are having a bacterial infection they may appear lethargic and display a lack of appetite. Their colour may also become pale, and it’s highly likely that you’ll see skin ulcers or skin haemorrhages on your fish. Although most bacterial infections can be treated effectively, you must not neglect the symptoms.

Anchor Worms

Have you seen tiny green or red worms attached to your fish? Or have you spotted ulcers on your fish? If so, this may be a case of anchor worms. Your fish may also look like they are having difficulties breathing as well as performing constant rubbing or flashing.

fish fungus

Fish Fungus

Have several of your fish died simultaneously in your pond? Or have you noticed that your fish look stressed and have mucus-looking substance on their gills? This could be caused by fungus. Another tell-tale sign of fungal attack is when your fish change colour.

Fish Parasites

There are a number of symptoms that can provide evidence of the fact that skin parasites are hurting your fish. Look out for lethargic-looking fish,  frequent gill movements, ulcers and sores, or a milky look on your fish. If you notice any of these, it’s possible that you have harmful skin parasites in your pond.

fish lice

Fish Lice

If your fish seem to display heightened stress levels and constantly rub themselves against objects, this can mean that you have a case of fish lice in your pond. Fish lice will also cause fish to develop open wounds as well as tiny black or red spots on the skin.

Fish Viruses

If your fish have an enlarged spleen or kidney, develop lesions on their gills, display ascites (a distended or swollen body with protruding scales also known as Dropsy due to a build up of fluid in its body cavity and internal organs), or a darker change in skin colour, these are all signs that can point to a possible case of virus attack on your fish.
