Coral Identifier: Reef Corals helps you identify marine and reef corals from photos using AI-based image analysis. Simply take or upload a photo and receive a suggested coral identification designed specifically for saltwater tanks and reef aquariums. This app is built for reef aquarium hobbyists who want a practical tool for photo-based coral identification while understanding that coral identification from images can be uncertain. Coral Identifier analyzes visual features to suggest possible coral species commonly found in marine aquariums, including SPS, LPS, and soft corals. Identification results are presented with confidence levels and should be treated as guidance rather than guaranteed results. For each identification, the app provides structured coral information such as coral type, general lighting and flow preferences, reef tank suitability, and basic care considerations to support reef aquarium decision-making. Photo ID works best with clear, well-lit coral photos taken in reef aquariums. When confidence is low, the app avoids guessing and may return limited or no identification to ensure transparency and trust. Coral Identifier is designed to support learning and decision-making for marine aquarium enthusiasts, not to replace expert knowledge or professional coral assessment. Key features: AI-powered coral identification from photos Photo ID for saltwater tanks and reef aquariums Recognition of SPS, LPS, and soft corals Structured coral information for reef tanks General coral care guidance including lighting and flow Confidence-based identification results Clean and easy-to-use interface This app is ideal for reef aquarium hobbyists, saltwater tank owners, marine coral enthusiasts, and anyone looking to identify reef corals from photos in saltwater aquariums.
