A. tenuis

Scientific Name: Acropora tenuis
Classification
: SPS - Bushy/corymbose species

Description:
Grows with straight outwards oriented round branches.  Coloration light brown or green with very attractive blue tips and edges to the radial corallites.  Axial corallites are prominent and radial corallites are a flattened and fairly distinct.  Polyps are large and fleshy, tan in color in this specimen and prominent day or night.

Veron: Colonies are corymbose clumps, usually with neat evenly spaced delicate branchlets, but branchlets may be irregular and prostrate.  Axial corallites are long and tubular.  Radial corallites are arranged in a neat rosette and have slightly flaring lips.  Color is yellow, cream, green or blue.  Colors may be bright with distinctively colored corallite lips..

Natural Environment:

Veron:  Upper reef slopes.

Care:

Lighting: Requires fairly strong lighting to maintain coloration. Recommend Metal halide or strong VHO/PC lighting. 

Water Current: Does well with medium to high water current levels.  This coral does not require as much water motion as some other SPS.

Temperature: Does well within a range of at least 75º to 84º F

Aggressiveness: Low. All corals can sting adjacent corals, but it does not have elongated stinging tentacles, so they can live in fairly close proximity to other non-aggressive corals.

Feeding: A. tenuis is photosynthetic and requires no direct feeding. That is why it is important to provide the proper lighting.  It will presumably take small zooplankton type foods if provided.

Supplements: Correct Calcium (400 – 500) and Alkalinity (3.2 – 4.5ml/eq.) levels are important for health and growth.  Low alkalinity levels can cause loss of blue color as can insufficient lighting.

Tank Positioning: Best if kept in the middle to upper portion of the tank where it can get maximum light and moderate to high water flow.  If your tank has very high intensity lighting, it is best to place any new coral on the bottom of the tank for a week or two to acclimatize it to your tank lighting conditions before moving it to it’s final location.
