Blue & Gold Cyphastrea

Cyphastrea is a popular small-polyp stony (SPS) coral, known for its distinct encrusting growth habit and often vibrant colour patterns. This variety features a deep blue base that perfectly contrasts its bright gold polyps. It's a good entry point into the world of SPS for many hobbyists, being a bit more forgiving than some of the more demanding branching species.

In the aquarium, Cyphastrea grows by spreading a thin layer of tissue directly over the rockwork, conforming to any shape it covers. The polyps are small and remain visible during the day, giving the colony a textured, bumpy appearance. The colour separation between the blue base and gold polyps is clean, creating a pattern that stands out well under both blue and full-spectrum lighting.

For care, this coral prefers lower to moderate light levels, somewhere in the 75-150 PAR range. Place it on the rockwork in the lower to middle sections of the tank where it receives moderate, indirect water flow. While it gets most of its nutrition from its symbiotic algae, it will respond well to occasional feedings of small particle coral foods. Like all SPS, it requires stable water parameters, with calcium at 420-440 ppm, alkalinity at 8-9 dKH, and magnesium between 1300-1400 ppm. It has short sweeper tentacles, so leave a few centimetres between it and its neighbours.

great species for adding colour to the lower light areas of a reef, where some other SPS might not thrive. Its steady encrusting growth can fill in bare spots on live rock, creating a very natural and mature look over time. It is generally peaceful, but its growth path should be considered during placement to avoid it slowly overgrowing sessile neighbours.

This is not a WYSIWYG listing; you'll receive a specimen of the same species with similar size and colouration to the one pictured, hand-picked for health and colour.

We take livestock seriously. That's why we don't sell anything we wouldn't be comfortable putting in our own tank.

As we are direct from source, we import and sell direct to the public. This means you can buy with confidence knowing EMA prides itself on excellent handling and conditioning protocols.

Fish

All our fish held in a quarantine system for a minimum of 3 weeks. During this time, regular water changes are performed, and twice daily (or sometimes more) feedings are performed.

Copper is dosed and checked twice a day for ich and velvet.

During this treatment fish are given formalin baths for brooklynella and a minimum of 3 praziquantel doses is performed for flukes.

Coral

Our coral is quarantined for a minimum of 3 weeks, just like fish. During this time, regular water changes are performed, water testing done, and once a month a Fauna Marin ICP Total is performed.

Corals are inspected for pests/general health and are provided with a pest dip once a week for at least 3 weeks.

If we see signs of pests, the quarantine period is extended and/or additional dips are performed

If coral is bleached/unhealthy, it will remain in quarantine until healthy enough to sell.
