Reef Life Identifier: ReefIQ
Sea Shell, Coral, Fish AI Scan
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Identify any fish, coral or invert in your tank or on the reef, check a sick fish or coral, and track your reef tank's water against reef targets.
ReefIQ identifies any fish, coral, invert or shell from a photo, checks a fish or coral that looks sick, and tracks your reef tank's water. Made for reef keepers, and for divers, snorkelers and beachcombers too.
IDENTIFY ANY SPECIES
Snap a fish, coral, shrimp, snail, crab or shell, in your tank, on a reef or in a tide pool. ReefIQ names it and tells you its size, diet, depth range, conservation status and a fun fact. For species kept in aquariums it adds the care level, the minimum tank size and whether it is reef compatible. Spotted a pest or hitchhiker? It says how harmful it is and how keepers remove it.
HEALTH CHECK
Worried about a fish or coral? Photograph it and get the most likely problem, how urgent it is, the signs to look for, the first steps for the next 24 hours and whether to quarantine.
MY TANK
Log your water tests: alkalinity, calcium, magnesium, nitrate, phosphate, salinity, temperature and pH. See each parameter against reef targets, how many are in range, a trend chart for each one and how much alkalinity your tank uses a day.
ASK A REEF EXPERT
Chat about an identification, your tank, stocking, pests, coral care or marine life in the wild. The chat knows your latest water test.
Every identification is saved in your history.
Available in English, German, Spanish, French, Italian, Japanese and Brazilian Portuguese.
