The fish start growing small white pin-prick like growths on their fins or skin and this is often mistaken for infection by Ichthyophthirius multifiliis in the early stages. It soon clumps together to form a cauliflower-like growth on the skin, mouth, fins, and occasionally the gills .
It causes a disease commonly referred to as white spot disease due to the macroscopically visible trophonts (up to 1 mm in diameter) in the skin and fins. The trophont, continuously rotating, is surrounded by host cells (epidermal cells and leukocytes), producing a minute elevation of the skin. These light-reflecting nodules are recognized as ...
Lesions begin at the base of the dorsal fin on the back of a fish and spread over time, hence the name saddleback disease. Ulcerations on the skin, and subsequent epidermal loss, identifiable as white or cloudy, fungus-like patches – particularly on the gill filaments, may appear. Mucus also accumulates on the gills, head and dorsal regions.
However, the disease can also develop without the fish showing any external signs of illness, the fish maintain a normal appetite, and then they suddenly die. The disease can progress slowly throughout an infected farm and, in the worst cases, death rates may approach 100 per cent. It is also a threat to the dwindling stocks of wild salmon.
Rosacea is a chronic skin condition that causes redness, flushing, and small bumps on the face that may be pus-filled, swollen, tender, [and] acne-like, says Dr. Kamangar. The rash can occur ...
Small, itchy bumps: These may be red, white, or yellow and can appear around the hair follicles. They can be mistaken for acne . Pain or tenderness: The affected areas might be sore or painful to ...
The following is a list of aquarium diseases. Aquarium fish are often susceptible to numerous diseases, due to the artificially limited and concentrated environment. New fish can sometimes introduce diseases to aquaria, and these can be difficult to diagnose and treat. Most fish diseases are also aggravated when the fish is stressed.
HLLE begins as small pits of receding epithelium (skin) around the fish's head and/or lateral line, and sometimes onto the unpaired fins. Rarely fatal, it does cause disfigurement, making the fish less suitable for public aquarium display. At least 20 families of fish have been identified as having developed HLLE in captivity.
