Overview: The Cobia (Rachycentron canadum) is a pelagic marine fish recognised for its streamlined shape and swift swimming capabilities. While more commonly found in open waters, it can be kept in very large marine aquariums by experienced hobbyists.
Care Level: Moderate to advanced. Due to its size potential and active nature, it requires a spacious tank and stable water conditions.
Temperament and Compatibility: Generally peaceful but active. It can coexist with other large, non-aggressive fish but may outcompete smaller or more timid species. Avoid housing with very small or slow-moving fish.
Diet: Carnivorous. Feed a varied diet including high-quality meaty foods such as chopped fish, shrimp, and specialised marine pellets to ensure optimal health.
Tank Requirements: Minimum tank size should be at least 1000 litres to accommodate its active swimming behaviour and potential growth. Provide open swimming areas with some hiding spots.
Water Parameters: Maintain stable marine conditions with temperature between 22-26°C, salinity at 1.020-1.025 SG, and good water quality with regular filtration and water changes.
Reef Compatibility: With Caution. Not recommended for reef tanks as it may prey on invertebrates or smaller fish.
Origin: Not Provided.
Maximum Size: Can grow significantly larger than the small variant offered; expect up to 1.5 metres in the wild, but smaller sizes are more manageable in captivity.
