Reading the Information Captured in a Single Photo
In online live animal purchases, listing photos are virtually the only means of communication with the seller. Since you cannot hold the actual specimen in your hands, the amount of information you can read from photos greatly influences most of your purchasing decisions. However, "beautiful photos ≠ healthy specimens." Because lighting, angles, and backgrounds can be manipulated, you need to systematically understand the key points to look for.
This guide explains tips for health checks common to live animal photos, from corals and saltwater fish to freshwater fish and reptiles.

First, Check the Body Surface, Skin, and Scales
The most important thing is the condition of the body surface. For fish, check whether the scales are arranged uniformly and whether the mucus membrane maintains adequate luster. The "pinecone condition" where scales appear raised, or white spots and cottony deposits are signs of infection. If the photo is clear, even white spots as small as a tweezers tip can be visible in the image.
For reptiles, pay attention to signs of incomplete shedding. If old skin remains on the fingertips or tail tips, it may indicate insufficient humidity management. Additionally, if the skin texture is uneven and has patchy discoloration, it could indicate viral disease or burn scars.
For corals, color contrast serves as a health indicator. Check whether the polyps are fully extended when photographed. If the polyps appear retracted or bleached, it indicates water quality stress or insufficient light. On the other hand, photos that are overexposed with fluorescent lighting may be intentionally emphasizing fluorescent colors, so ask the breeder to confirm the actual colors.

Check the Condition of Eyes, Gills, and Fins
The eyes are said to be "a mirror reflecting the condition of the specimen." Fish eyes should be clear with a glossy appearance, and the eyeball should not protrude (no popeye condition). If the eyes are cloudy or different sizes on each side, infection or injury is suspected.
The gills are difficult to confirm in photos, but if the image is taken from the side, you can check whether the gill cover is closing normally. If the gill cover is consistently slightly open or opens asymmetrically, it may suggest the presence of gill disease or parasites.
