Size: 0.75 inch Raven Blasto is a Blastomussa merleti known for its red/blue coloration and micro polyps. Its small and encrusting growth form make it a standout choice for reefers looking to add a more variety of LPS coral to lower areas of a mixed reef or dedicated LPS aquarium. This listing is for a frag of our Raven Blasto. Photos may include the parent colony for reference, so the coral you receive may vary slightly in size, coloration, shape, and number of heads. Each frag will be selected from the same coral strain and should be fully healed before shipment or pickup. For best results, place this Blasto in lower lighting with gentle, indirect flow. Avoid strong direct flow, which can prevent the polyps from expanding comfortably. Raven Blasto does best in an established reef aquarium with stable salinity, temperature, alkalinity, and nutrient levels. Color may vary depending on lighting spectrum, camera settings, screen settings, shipping stress, acclimation, and aquarium conditions.
