Possible coral identification

Coral group uncertain

A clearer close-up may be needed to distinguish visible growth structure.

Example visible condition

Reduced polyp extension

Extension can vary with lighting, flow, feeding, and recent disturbance.

What to do now

Record temperature, salinity, and alkalinity with suitable tests.
Review recent lighting and flow changes before adjusting the tank.
Compare photos under consistent lighting and seek specialist advice if tissue loss progresses.

Illustrative guidance, not a diagnosis of the pictured reef. Identification and possible contributors need verification; improvement is not guaranteed.

Clear expectations

Use guidance with care

Photos can miss important detail, and aquarium lighting can change how colors appear. Check readings with appropriate test methods and consult a qualified marine specialist when a coral is at risk.

Do I need an account to begin?

No. You can start an image analysis as a guest. Sign in to save it and organize tank history.

Is a coral name or health result guaranteed?

No. Coral identification and condition guidance are AI assisted and may be uncertain. Use the visible evidence as a starting point.

Should I change my tank based on one result?

Verify water measurements and consider recent changes before adjusting aquarium conditions. Do not use this service as a substitute for qualified specialist advice.

Ready to take a closer look?

Begin with one clear coral photo. Tank details and water readings are optional.
