Temperament - Fish, Corals, Invertebrates & Anemones
CCREEF Classification	Peaceful
Peaceful Species
Behavior	Peaceful species coexist well with others and do not exhibit territorial aggression. They thrive in stable environments and are generally tolerant of neighbors. Some peaceful corals may grow rapidly under ideal conditions, occasionally shading out smaller organisms.
Examples Fish	Clownfish – Social fish that forms bonds with anemones and rarely show aggression. Royal Gramma – Passive but will defend its hiding spot if threatened. Gobies – Bottom dwellers known for their cooperative nature with tank mates. Blennies – Calm, reef-safe fish with minimal territorial instincts. Chromis – Schooling fish that thrive in peaceful community tanks. Tangs – Generally peaceful but may display minor territorial behavior, especially toward other tangs.
Examples Corals & Invertebrates	Soft Corals – Non-aggressive and fast-growing, providing movement in reef tanks. Zoanthids – Hardy coral that spreads easily but does not attack neighbors. Feather Dusters – Filter feeders that add diversity without displaying aggression. Cleaner Shrimp – Actively clean fish and maintain a symbiotic relationship with tank mates.
Semi-aggressive Species
Behavior	Require extra space as they grow. Some species expand significantly and may use chemical defenses to maintain their territory.
Examples Fish	Flame Angelfish – May nip at corals and other angelfish if kept in confined spaces. Six-line Wrasse – Active and territorial, especially toward similar fish. Hawkfish – Perches on rocks but can become dominant over smaller fish. Dwarf Lionfish – Prefers solitude but may prey on small tank mates when hungry.
Examples Corals & Invertebrates	Candy Cane Coral – Grows in clusters but does not actively sting neighboring corals. Bubble Coral – Inflates large but is primarily defensive rather than aggressive. Brain Coral – Large-growing but does not use sweeper tentacles for defense. Anemones – May capture small prey but do not actively attack other corals. Crabs – Some species may challenge smaller fish or corals for territory. Large Leather Corals – Can release toxins in confined spaces to deter competitors.
Aggressive Species
Behavior	Use sweeper tentacles (acontial filaments) or chemical defenses to deter competition. Some species can sting and kill neighboring specimens within hours.
Examples Fish	Undulated Triggerfish – Highly territorial and prone to attacking tank mates. Green Moray Eel – Large predator known for its powerful bite and ambush hunting. Puffers – Inflate when threatened and may nip at other fish or invertebrates. Groupers – Aggressive feeders that may consume smaller fish in the tank.
Examples Corals	Torch Coral – Uses long sweeper tentacles to sting and kill neighbors. Frogspawn Coral – Expands aggressively and defends territory through stinging mechanisms. Hammer Coral – Can sting and kill nearby corals if placed too close.
Examples Aggressive Invertebrates	Mantis Shrimp – Powerful striker capable of cracking shells and even aquarium glass. Fireworm – Venomous bristles that sting corals, fish, and even humans. Large Carpet Anemones – Can capture and consume small fish or crustaceans that come too close.

Care Level Classification for Fish, Corals, Invertebrates & Anemones
CCREEF Classification	Easy
Easy
Behavior	Species are hardy and low-maintenance, thriving in a wide range of water conditions. Fish: Typically adaptable and peaceful, requiring minimal special care. Corals: Fast-growing with little sensitivity to parameter fluctuations. Invertebrates: Hardy cleaners like snails and shrimp, requiring basic care. Anemones: Beginner-friendly varieties with stable environmental needs.
Moderate
Behavior	Species require consistent conditions and moderate care to remain healthy. Fish: Can become territorial, requiring proper tank space and monitoring. Corals: Sensitive to major water fluctuations and require moderate lighting. Invertebrates: Some crabs and shrimp may display aggression or require species-specific diets. Anemones: Require stable water conditions but tolerate minor fluctuations.
Difficult
Behavior	Advanced care needed for delicate species with specific requirements. Fish: Often aggressive or large predators requiring specialized diets. Corals: Require precise lighting, flow, and nutrient levels to thrive. Invertebrates: Some species have unique feeding habits or need pristine water quality. Anemones: Need consistent lighting, controlled parameters, and long-term stability.
Expert
Behavior	Extremely challenging species, recommended for expert aquarists or research institutions. Fish: Require highly specialized care, feeding schedules, and monitoring. Corals: Most sensitive species, demanding highly stable environments. Invertebrates: Rare or exotic species that require continuous care. Anemones: Highly specialized requirements, often needing dedicated systems. Fail-safes, backup power systems, and advanced monitoring equipment strongly recommended.
