Dive Deeper: Info & Tips for Non-Reef Safe Fish
Non-reef safe saltwater fish may be predatory, coral-nipping, or simply incompatible with the peaceful ecosystem of a mixed reef. However, many of these species are ideal for dedicated FOWLR systems or aggressive community tanks. They’re often hardier and more interactive than their reef-safe counterparts, making them popular for aquarists who enjoy bold, behavior-rich displays.
These fish vary widely in size, diet, and care needs. Some, like large angels and butterflyfish, are occasional nippers that might thrive in soft coral tanks with caution. Others, like triggers, lionfish, and puffers, are true non-reef safe predatory fish and will actively eat small inverts or tankmates. Planning your aquascape and tank mates carefully is key to long-term success.
Some saltwater fish simply aren’t suited for reef aquariums—and that’s okay. Our Non-Reef Safe Saltwater Fish collection includes bold, fascinating species that may nip at corals or invertebrates, making them better suited for fish-only or FOWLR (fish-only-with-live-rock) systems. These fish often exhibit vibrant coloration, strong personalities, and unique predatory behaviors that make them stand-out additions to the right setup.
At Top Shelf Aquatics, we curate our non-reef safe fish selection to offer a range of options for aquarists looking to build tanks without coral or delicate inverts. Whether you're interested in a striking angelfish, an assertive triggerfish, or a show-stopping puffer, this collection focuses on species that thrive in environments where their natural behaviors can be expressed freely.
Top Non-Reef Safe Saltwater Fish
Queen Angelfish – One of the most visually stunning angelfish, known for its size and coral-nipping behavior. Best kept in large FOWLR tanks.
Clown Triggerfish – A predatory, aggressive species with striking markings. Should be housed with equally assertive fish in larger systems.
Porcupine Puffer – A personable, intelligent fish with a curious nature. Will eat inverts and needs room to grow.
Emperor Angelfish – Gorgeous as both juvenile and adult, but not reef safe. Requires ample space and a mature tank.
Lionfish – A slow-moving, venomous predator that can be a centerpiece in predator tanks. Avoid housing with small fish or shrimp.
Butterflyfish – Many species feed on coral polyps and require specific diets. Best kept in species-specific or FOWLR environments.
Ideal Parameter Range

- pH: 8.1–8.4
- Ammonia/Nitrite: 0 ppm
- Nitrate: Less than 20 ppm
Setting Up a Tank for Non-Reef Safe Fish
When keeping non-reef safe fish, aquascaping becomes especially important. Use stable rock structures to create caves and territories, and ensure there’s plenty of open swimming space for larger, active species. Filtration should be strong, as many predatory fish produce more waste than reef-safe counterparts.
Tank mates should be chosen carefully. Avoid combining overly aggressive species with timid fish, and always consider adult size and behavior when planning your livestock. A tight-fitting lid is also essential for many species prone to jumping.
Feeding Non-Reef Safe Saltwater Fish
Most non-reef safe saltwater fish are carnivores or omnivores that need protein-rich diets. Feed a mix of frozen seafood (like squid, shrimp, and clam), marine pellets, and occasional live foods for enrichment.
Feed 1–2 times daily, depending on species and tank dynamics. Use tongs or target feeding for fish with poor vision or unique feeding habits, such as lionfish or puffers.
