TIA Golden Coin Tenuis: Bright Gold With Green and Orange Highlights
The TIA Golden Coin Tenuis mother colony — the coral your frag is cut from — under Actinic Radion Mobius lighting. Colors shift under different lighting; each piece is cut to order.
What is TIA Golden Coin Tenuis?
TIA Golden Coin is an aquacultured Acropora tenuis and one of the most radiant golden tenuis TIA has grown. It carries an intensely bright gold, with subtle green and orange working across the branches for a layered palette. The color shifts with lighting and viewing angle, so it never quite looks the same twice.
The story
Golden Coin is one of the most radiant golden tenuis TIA has grown. Like Pineapple Express, it carries an intensely bright gold that catches the eye the moment it hits reef lighting. What sets Golden Coin apart is the complexity inside the gold — subtle green and orange work their way across the branches, giving it a richer, more layered palette. The color shifts slightly with lighting and viewing angle, so it never quite looks the same twice.
Care requirements
Care level: Intermediate to Advanced — recommended for aquarists experienced with SPS husbandry.

Buying a Golden Coin frag
Every piece is cut to order from the mother colony. After we cut your frag, we send you a video of it, and we recommend allowing about 14 days of heal time before expecting full recovery. Every order is covered by TIA's 3-day live-arrival guarantee, and TIA has grown and named collector corals since 2008.

Frequently asked questions
What color is TIA Golden Coin Tenuis? Golden Coin carries an intensely bright gold, with subtle green and orange working across the branches for a richer, more layered palette. The tones shift with lighting and viewing angle, so the coral never quite looks the same twice.
What is an Acropora tenuis? Tenuis is a classic Acropora form — upward branching with prominent axial (tip) corallites. Golden Coin shows that classic tenuis growth and does best in the upper half of a mature reef under strong blue-spectrum light.
How much light does TIA Golden Coin need? Moderate to high light, PAR 250–400. Strong blue-spectrum reef lighting brings out the gold along with the green and orange highlights. Pair it with moderate-to-strong random/turbulent flow in the upper half of a mature reef.
Is TIA Golden Coin beginner-friendly? No — it is rated Intermediate to Advanced, recommended for aquarists experienced with SPS husbandry. Target 76–79 °F, salinity 1.025–1.026, alkalinity 8–9 dKH, calcium 400–450 ppm, and magnesium 1300–1400 ppm. It is reef safe.
