Red Coris Wrasse - Adult Phase

Adult Red Coris Wrasse (Coris gaimard), showcasing the dramatic shift from its juvenile phase: 1. Appearance & Coloration Adult Coloration: Adults undergo a complete transformation. Instead of the bright orange-red body with white saddles seen in juveniles, mature adults feature a striking bluish-green to bluish-gray body speckled with vibrant blue or yellow dots. Their face turns an intricate mix of green and orange with distinct green lines, and they finish off with a bright yellow tail. Size: They grow into large, powerful fish reaching up to 12 to 16 inches (30 to 40 cm) in length. 2. Native Origin & Habitat Geography: Found widely throughout the Indo-Pacific region. Environment: Inhabits coral-rich reefs, outer reef slopes, and sandy lagoon flats where they have access to open swimming areas and rubble fields. 3. Tank Requirements Minimum Tank Size: Requires a very large system of at least 125 to 150+ gallons (with many advanced hobbyists recommending 180+ gallons) to accommodate their active swimming habits and large adult size. Deep Sand Bed: A deep sand bed (3 to 5 inches) consisting of fine aragonite sand is mandatory. Adults dive forcefully into the sand to sleep every night. Secured Aquascaping: Because adults aggressively flip rocks and rubble while hunting, all heavy live rock structures must be securely mortared or epoxied down to prevent dangerous rockfalls. Tank Cover: A tightly secured lid or heavy-duty screen top is essential to prevent them from jumping. 4. Diet & Feeding Natural Diet: Apex crustacean hunters that use their strong jaws and prominent front teeth to crush shells, turning over substrate and rocks to feed. Captive Diet: Voracious carnivores that require multiple feedings a day. Provide a heavy-duty diet of chopped marine meats, shrimp (mysis, krill, raw table shrimp), clams, squid, and hard-shelled or crunchy foods to keep their teeth healthy. 5. Reef Compatibility Status: Strictly Not Reef Safe Behavior: Adults will actively hunt and consume any ornamental invertebrates in the tank, including decorative shrimp, crabs, snails, and urchins. Furthermore, their constant rock-flipping and sand-shifting behavior can easily knock over coral frags and disrupt standard reef aquascapes. They are best kept in large Fish-Only-With-Live-Rock (FOWLR) setups. 6. Temperament & Tank Mates Temperament: Semi-aggressive to outright aggressive and territorial. As they mature into powerful adults, they lose the docility of their youth and can become dominant bullies. Compatibility: Best housed with other large, robust, and assertive fish (such as large tangs, triggerfish, or large angelfish) that can hold their own. Avoid housing them with timid, passive species, small community fish, or nano tankmates that will be harassed or consumed.
