{"product_id":"niger-triggerfish-sol","title":"Niger Triggerfish - Solomon Is.","description":"\u003cp\u003eThe Solomon Islands Niger Triggerfish, \u003cem\u003eOdonus niger\u003c\/em\u003e, is a striking saltwater fish known for its deep blue to violet coloration, flowing crescent-shaped tail, and distinctive red teeth that become increasingly prominent as the fish matures. Depending on lighting and mood, the body can shift between rich blue, purple, and blue-green tones, while pale blue edging along the fins adds further contrast. Mature specimens develop an especially streamlined, powerful appearance that makes them a dramatic centerpiece for large marine aquariums.\u003c\/p\u003e\n\u003cp\u003eThis offering represents \u003cem\u003eOdonus niger\u003c\/em\u003e originating from the Solomon Islands in the western Pacific. In nature, the species inhabits current-swept seaward coral reefs and commonly forms aggregations above the reef while feeding on zooplankton. This open-water feeding behavior distinguishes it from many more benthic triggerfish and contributes to its relatively good coral compatibility. Although generally less aggressive than many triggerfish, it remains a substantial, semi-aggressive marine aquarium fish best suited to large fish-only systems or carefully planned reef aquariums.\u003c\/p\u003e\n\u003ch2\u003eQuick Care Guide\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eCare Level:\u003c\/strong\u003e Moderate\u003cbr\u003e\u003cstrong\u003eMinimum Tank Size:\u003c\/strong\u003e 180 gallons\u003cbr\u003e\u003cstrong\u003eTemperament:\u003c\/strong\u003e Semi-aggressive\u003cbr\u003e\u003cstrong\u003eDiet:\u003c\/strong\u003e Planktivore \/ Carnivore\u003cbr\u003e\u003cstrong\u003eReef Safe:\u003c\/strong\u003e With Caution\u003cbr\u003e\u003cstrong\u003eRegion:\u003c\/strong\u003e Solomon Islands, Western Pacific\u003cbr\u003e\u003cstrong\u003eScientific Name:\u003c\/strong\u003e \u003cem\u003eOdonus niger\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eTank Requirements\u003c\/h2\u003e\n\u003cp\u003eThe Niger Triggerfish requires a spacious aquarium with extensive open swimming room. Adults can reach approximately 20 inches in total length, making a 180-gallon or larger aquarium appropriate for long-term housing.\u003c\/p\u003e\n\u003cp\u003eArrange sturdy rockwork to create caves, overhangs, and protected crevices while maintaining generous open-water areas. Like other triggerfish, this species can lock its dorsal spine into rockwork when resting or frightened, so shelters should be large enough to accommodate the fish comfortably.\u003c\/p\u003e\n\u003cp\u003eModerate to strong water movement and excellent oxygenation are particularly appropriate for this species because it naturally inhabits current-swept reef environments. Efficient filtration is also important due to the feeding requirements and waste production of mature specimens.\u003c\/p\u003e\n\u003cp\u003eSecure loose rockwork and decorations carefully, and use a secure aquarium cover, particularly during acclimation.\u003c\/p\u003e\n\u003ch2\u003eDiet and Feeding\u003c\/h2\u003e\n\u003cp\u003eThe Niger Triggerfish is primarily a planktivore and carnivore. In the wild, it feeds extensively on zooplankton in the water column while also consuming sponges and other animal material.\u003c\/p\u003e\n\u003cp\u003eOffer a varied captive diet including mysis shrimp, enriched brine shrimp, krill, chopped shrimp, squid, clam, mussel, and quality frozen plankton or carnivore blends. High-quality marine pellets can also become a useful part of the regular feeding routine.\u003c\/p\u003e\n\u003cp\u003eOccasional appropriately sized shell-on marine foods provide dietary variety and encourage natural chewing behavior. Feed once or twice daily, or divide the daily ration into smaller feedings for active specimens.\u003c\/p\u003e\n\u003ch2\u003eTemperament and Tankmates\u003c\/h2\u003e\n\u003cp\u003eThe Niger Triggerfish is generally considered one of the less aggressive triggerfish, but it should still be treated as semi-aggressive. Territorial behavior may become more pronounced as the fish matures.\u003c\/p\u003e\n\u003cp\u003eSuitable tankmates include appropriately sized tangs, rabbitfish, angelfish, larger wrasses, groupers, and other robust marine fish. Very small, timid, or slow-feeding species may be intimidated or outcompeted by a large adult.\u003c\/p\u003e\n\u003cp\u003eUse caution when housing it with other triggerfish. Multiple large triggerfish require substantial aquarium space, clearly defined territories, and carefully planned introductions.\u003c\/p\u003e\n\u003ch2\u003eReef Compatibility\u003c\/h2\u003e\n\u003cp\u003eThe Niger Triggerfish is best classified as \u003cstrong\u003ereef safe with caution\u003c\/strong\u003e.

Provide strong rockwork for shelter and exploration, along with moderate to strong water movement. A secure lid is a must, as triggers can jump and displace lids with their powerful jaws. Best kept in a mature tank with stable parameters and ample territory.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eColor, Personality, and Hardiness\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eJuveniles show brilliant blue-violet tones and grow into darker, iridescent adults with subtle green hues and a signature tail stream. Known for their high intelligence and curiosity, Niger Triggers will often \"watch\" you and interact with their environment.

Feed a mix of frozen silversides, squid, shrimp, clam, marine pellets, and occasional algae-based offerings. Multiple daily feedings support growth and health. Include shelled foods (like clams or krill) to help wear down their continuously growing teeth.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eTankmates and Behavior\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eWhile less aggressive than many triggerfish, the Niger Trigger can become territorial as it matures—especially in tight quarters. Best kept with similarly sized or larger tankmates that can handle its assertiveness. Avoid small, delicate fish and ornamental shrimp. Though not reef-safe in all cases, some individuals coexist peacefully with corals and large inverts in well-managed setups. Exercise caution and monitor closely.\u003c\/p\u003e","brand":"TSA Fish","offers":[{"title":"S","offer_id":52341412167978,"sku":"TRIGGERxNigerSoS","price":68.99,"currency_code":"USD","in_stock":false},{"title":"SM","offer_id":52341412200746,"sku":"TRIGGERxNigerSoSM","price":74.99,"currency_code":"USD","in_stock":false},{"title":"M","offer_id":52341412233514,"sku":"TRIGGERxNigerSoM","price":80.99,"currency_code":"USD","in_stock":false},{"title":"ML","offer_id":52341412266282,"sku":"TRIGGERxNigerSoML","price":110.99,"currency_code":"USD","in_stock":false},{"title":"L","offer_id":52341412299050,"sku":"TRIGGERxNigerSoL","price":158.99,"currency_code":"USD","in_stock":false},{"title":"XL","offer_id":52341412331818,"sku":"TRIGGERxNigerSoX","price":239.99,"currency_code":"USD","in_stock":false},{"title":"XX","offer_id":52341412364586,"sku":"TRIGGERxNigerSoXX","price":251.99,"currency_code":"USD","in_stock":false},{"title":"SH","offer_id":52341412397354,"sku":"TRIGGERxNigerSoSH","price":428.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/0873\/7322\/files\/NigerTrigger_c7235cba-6076-4057-a27c-0c2580249024.png?v=1787768894","url":"https:\/\/topshelfaquatics.com\/products\/niger-triggerfish-sol","provider":"Top Shelf Aquatics ","version":"1.0","type":"link"}
