Thick upright branches develop from a sturdy base, each covered in dense pointed hydnophores that give the coral its characteristic spiked appearance.\n\u003c\/p\u003e\n\n\u003cp\u003e\nUnder reef lighting the coral glows a vivid electric green, with small polyps extending between the skeletal projections to create subtle surface movement. As the colony matures, the branches thicken and develop into a bold branching structure that stands out strongly among smoother SPS corals.\n\u003c\/p\u003e\n\n\u003cp\u003e\nThis coral adds vertical structure and bright coloration to SPS-dominated aquariums. Its rugged branch texture contrasts particularly well with plating Montipora or finer branching Acropora, making it a visually distinct coral even in densely stocked reef systems.\n\u003c\/p\u003e\n\n\u003cp\u003e\nWe used the \u003ca href=\"https:\/\/ndaquaculture.ca\/collections\/reef-charge\/products\/hydroshock-3-part-complete-system\"\u003eHydroShock 3 Part Complete System\u003c\/a\u003e to grow this coral. It includes calcium, alkalinity, magnesium, and trace elements in the ratios that corals consume them.\n\u003c\/p\u003e\n\n\u003ch3\u003eCare Requirements\u003c\/h3\u003e\n\u003cp\u003e\n\u003cem\u003eHydnophora exesa\u003c\/em\u003e is generally considered a hardy SPS coral once established but benefits from stable reef parameters and consistent lighting. Moderate to high lighting and moderate to strong water movement help maintain coloration and keep the coral surface clean.\n\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLighting:\u003c\/strong\u003e Moderate to high reef lighting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow:\u003c\/strong\u003e Moderate to strong, turbulent flow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlacement:\u003c\/strong\u003e Mid to upper rockwork with space for branch growth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth Form:\u003c\/strong\u003e Thick branching with dense pointed hydnophores\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\nProviding space around the colony allows branches to develop naturally and helps prevent contact with nearby corals as the coral grows.\n\u003c\/p\u003e\n\n\u003ch3\u003eFeeding \u0026amp; Nutrition\u003c\/h3\u003e\n\u003cp\u003e\nLike most reef-building corals, Glowstick Hydnophora receives much of its energy through photosynthesis from symbiotic zooxanthellae. A balanced reef environment with dissolved nutrients, plankton availability, and active microbial communities can further support coral health.\n\u003c\/p\u003e\n\n\u003cp\u003e\nMany reef aquariums benefit from regular additions of live plankton and beneficial microbial populations.

Rapid parameter swings, nutrient instability, or stress during acclimation may affect newly introduced colonies until they adjust to the system.\n\u003c\/p\u003e\n\n\u003ch3\u003eShipping \u0026amp; Arrival Guarantee\u003c\/h3\u003e\n\u003cp\u003e\nAll corals are carefully packed to maintain stable conditions during transit.
