Fish Crazy
Here are the symptoms of the most common diseases and their names:
Skins and Fins
Obvious Parasites
Spherical or Oval, smooth yellowish cysts, up to 1cm (0.4 inches) across, on skin, fins and gills - Nodular Diseases
Dusting or Gold on skin and fins. Skin peeling away in strips - Velvet Disease (see also White Spot)
Worm-Like parasites, up to 4cm (2 inches) long, attached to skin and fins by sucking discs at each end. Reddened areas indicate previous attachment points. Generally in ponds only - Leech Infestation
Fungus-like growths, especially around the mouth. Reddened ulcers on the body and frayed fins - Cotton wool disease (See also Fish Fungus)
Cotton-wool-like tufts on the skin, usually white but possibly grey or brown in colour - Fish Fungus (See also Cotton Wool Disease)
Black Spots (cysts), up to 2mm (0.08 inches) across, on skin and fins. Yellowish cysts also occur - Black spot, etc.
White, maggot-like parasites, up to several millimetres long, on gills, gill cover and inside mouth - Gill Maggots
Elongated, twig-like parasites, up to 2cm (0.8 inches) long, deeply embedded in body wall. Distinctive twin egg sacs at free end - Anchor Worm
Sprinkling of white spots, each up to 1mm (0.04 inches) across, on skin, fins and gills - White Spot Disease (See also Guppy Disease)
Disc-shaped parasite, up to 1cm (0.4 inches) across, clinging tightly to skin and fins. Reddened lesions where parasites have fed - Fish Lice
Skins and Fins
Lesions, Lumps and Bumps
Protruding scales and swollen belly, often giving a 'pine cone' effect, reddening at fin bases or vent - Dropsy
Split, ragged or stumpy fins, often with a white edge - Finrot (See also Cotton Wool Disease)
Grey-white film of excess mucus on skin, plus scratching and/or rapid gill movements - Sliminess of the skin
Grey edges to fins and/or gills with no other symptoms. Only in fish that have been kept with freshwater mussels - Glochidial Infestation
Small Holes in the body, particularly in the head region. Lesions may enlarge and produce yellowish mucus trails - Hole-in-the-head Disease
Rough raspberry- or cauliflower-like growths on skin and fins - Lymphocystis (See also Fish Pox)
Lesions, ulcers or sores on the body, plus reddening at fin bases and vent - Ulcer Disease (See also Physical Damage)
Smooth White, grey or pink growths on skin and fins often looking like molten wax. Extreme growths may take the colour of surrounding tissue - Fish Pox (See also Lymphocystis)
Obvious signs of damage, such as loss of scales, bleeding, split or ragged fins - Physical Damage
Unusual growths or swellings clearly visible on any part of the fish's body - Tumours
Pale shallow lesions on skin, plus other symptoms such as hollow-bellied appearence, 'pop-eye', colour loss and listlessness - Wasting Disease/Fish TB
Eyes
Cloudy lens, with no other symptoms - Eye Fluke
Bulging eye or eyes, together with swollen belly and raised scales - Dropsy
One or both eyes protrude in an abnormal way, but no other obvious symptoms - Pop-eye
Bulging eye or eyes, together with skin lesions and emaciation - Wasting Disease/Fish TB
Cloudy eyes, together with poor growth and bleeding at fin bases - Nutritional problems
Eye lost from socket, with no other obvious symptoms - Physical Damage
Shape, colour and Behaviour
Unnatural swimming behaviour, 'listing' to one side or even floating on side or back - Swimbladder Disorders
Long, pale, faecal cast, perhaps with darkening of colour, pop-eye, and loss of appetite - Dropsy (See also Hole-in-the-head Disease)
Loss of colour, unusual swimming behaviour, emaciation, spinal curvature and finrot - Neon Tetra Disease
Thin emaciated appearance without other obvious symptoms - Worms in the intestine
Thin appearance, gasping gills, gasping at surface, listless behaviour - Water quality problems (See also Gill Disease)
Bulges apparent within body (and also perhaps on the outside) - Nodular Diseases
Thin, emaciated appearance, listless behaviour, anaemia and perhaps bulging eyes - Blood Parasites (See also Wasting Disease & Hole-in-the-head-Disease)
Bloated body, darkening of coloration and lack of appetite - Dropsy
Firm noticeable swellings that distort the body shape - Tumours
Red 'paintbrush' of worms protruding from vent, perhaps associated with emaciated appearance - Worms In The Intestine (Camallanus)
Peculiar swimming behaviour, rapid gill movements, gasping at water surface, inactive on bottom, generally 'off colour' - Water Quality Problems
Swollen belly and impaired swimming behaviour. Scales do not stick out - Worms In The Body Cavity
Pests
Green water, green threadlike growths, brownish filmlike growths and/or dark green slimy sheets over rocks, plants and substrate - Algal Problems
Bean-shaped creatures up to 3mm (0.1 inches) in size. Scuttle over the substrate and plants - Ostracods
Larval beetles, such as Dytiscus marginalis, with fearsome-looking curved jaws. Up to 5cm (2 inches) long - Beetles
Adult Beetes, such as Dytiscus marginalis, up to 3cm (1.2 inches) long - Beetles
Dragonfly nymphs with retractable jaws, such as Aeshna, up to about 4cm (1.6 inches) long - Dragonflies
Large numbers of snails - Snails
Masses of whitish, coral -like polyps profusely ringed with tentacles. Up to several cm in height. Only in marine tanks - Aiptasia
Soft-bodied, stalk-like polyps, each with a ring of tentacles, attached to plants and rocks. Up to about 2.5cm (1 inch) in height - Hydra
Hordes of tiny, insect-like creatures about 1mm (0.04 inches) long clustered on the damp glass just above the waterline - Mites
White, cream or orange flattened worms with arrow-shaped heads. Up to 1cm (0.4 inches) long - Flatworms
If anybody has any good pictures of any of these diseases, please send them to me so I can add them to this post.
