Medium Red Cynarina Coral – Radiant Colour and Elegant Form for Reef Tanks
The medium Red Cynarina Coral, also known as Cynarina lacrymalis, is a showstopping addition to any reef aquarium. Its vibrant red colouration and softly textured, inflated body create a mesmerising presence under actinic or blue-spectrum lighting. The coral’s signature dome shape, central mouth, and expanded folds provide dynamic appeal and a sense of vitality within your aquascape.
This coral is solitary and slow-growing, making it an excellent centrepiece for small to mid-sized reef tanks. It does not require aggressive lighting or intense water flow, and it is compatible with a wide range of peaceful tank inhabitants. Due to its semi-aggressive nature, sufficient spacing from neighbouring corals is essential to avoid tissue damage from sweeper tentacles.
Lighting Needs:
-
Performs best under low to moderate light intensity (75–125 PAR)
-
Enhances red tones under actinic or blue LEDs
-
Avoid placing directly under high-intensity lighting without acclimatisation
Water Flow:
-
Thrives in gentle, low water movement
-
High flow may prevent full polyp expansion and cause stress
-
Position away from strong directional currents
Aquarium Compatibility:
-
Suitable for nano, medium, and large-sized aquariums
-
Requires at least 5–10 cm spacing from other corals due to potential stinging
-
Best kept in systems with stable water conditions and peaceful tank mates
Feeding Recommendations:
Though largely photosynthetic, the Red Cynarina benefits from occasional direct feeding. Ideal feeding times are during low light periods when feeding tentacles extend.
Feed 1–2 times per week using:
-
Mysis shrimp
-
Brine shrimp
-
Marine pellet pastes or coral-specific blends
