Description
Bush Soft Coral – Red (Neospongodes sp.)
(Also known as Red Tree Coral or Red Bush Coral)
Overview
The Red Bush Soft Coral (Neospongodes sp.) is a striking and colourful soft coral known for its branching, tree-like structure and deep red to pink polyps. It forms dense, bushy colonies that sway gracefully in the current, adding vivid contrast and texture to marine aquariums. While beautiful, this species can be moderately challenging, as it often prefers moderate flow and occasional feeding to thrive. It does not contain symbiotic zooxanthellae, meaning it depends more on direct feeding than light for nutrition.
Origin
Found throughout the Indo-Pacific region, including Indonesia, the Philippines, and the Great Barrier Reef. Typically inhabits shaded reef slopes, overhangs, and deeper waters where light is dim and currents bring abundant plankton.
Lighting
Low to moderate lighting. Unlike photosynthetic corals, Neospongodes species derive little to no energy from light. Too much direct light can cause tissue recession. Best placed in shaded or lower regions of the tank, such as under rock ledges or overhangs.
Water Flow
Moderate to strong, indirect flow. This keeps polyps extended and helps deliver planktonic food while preventing detritus buildup. Avoid direct blasting from powerheads, which may damage delicate branches.
Feeding
The Red Bush Coral is a non-photosynthetic (NPS) or partially heterotrophic coral that requires regular feeding. Provide small, frequent feedings of:
-
Phytoplankton
-
Zooplankton
-
Marine snow or coral-specific micro foods
-
Finely minced meaty foods (rotifers, copepods, or cyclops)
Feed 2–4 times per week, ideally when polyps are fully extended (usually during low light or night hours).
Placement
Position in the lower to mid-section of the aquarium in an area with gentle to moderate water movement and indirect light. Mount securely to live rock, as colonies can become top-heavy as they grow.
Tank Mates
Compatible with most reef-safe fish and invertebrates. Avoid:
-
Aggressive coral species with strong sweeper tentacles (e.g., Euphyllia, Galaxea)
-
Predatory fish or invertebrates that may nip soft corals
Aggression
Peaceful, but can release mild chemical deterrents (allelopathy) when crowded by other soft corals. Allow space and ensure good water circulation and carbon filtration to minimise chemical competition.
Experience Level
Intermediate to advanced. Requires stable water parameters, supplemental feeding, and appropriate low-light placement. Long-term success depends on consistent feeding and good nutrient export.
Water Parameters
-
Temperature: 24–27°C (75–81°F)
-
pH: 8.1–8.4
-
Salinity: 1.024–1.026 SG
-
Hardness (dKH): 8–12
-
Calcium: 400–450 ppm
-
Tank Size: Minimum 50 gallons (190L) for stable conditions
Maintain excellent water quality with regular partial water changes and protein skimming, as overfeeding can raise nutrient levels.
