General Description
Rainbow Wrasses, scientifically known as Coris caudimacula, belong to the Labridae family. These fish undergo a significant transformation in appearance from juvenile to adult stages. They are known for their large size and vibrant colors.
Aquarium Suitability
The Spottail Coris, also referred to as Tailspot wrasse, Spot-tail wrasse, or Spottail coris, is considered suitable for aquariums with caution. They are hardy fish with a minimum tank size requirement of 800 liters. However, their potential aggressiveness towards smaller fish and tendency to hunt crustaceans and worms need to be taken into account.
Demands
As hermaphroditic species, the Spottail Coris has the ability to change gender from female to male. They prefer deep sandy substrates of at least 2 inches for burrowing when threatened or resting. These fish have a preference for hiding initially and may rearrange rocks and sand in their environment.
Care and Hardiness
Rainbow Wrasses are known to acclimate better as juveniles and require a varied diet that includes larger crustaceans and small invertebrates. They are hardy marine fish with a temperature range of 22.2-25.6 degrees Celsius and water conditions of pH 8.1-8.4, KH 8-12, and specific gravity of 1.020-1.025.
Reef Suitability
The Spottail Coris is not considered reef-safe due to its hunting behavior, which can pose a threat to small invertebrates and other tank inhabitants in a reef setup.
Aquarium Setup
Setting up an aquarium for Rainbow Wrasses should include a deep sandy substrate, securely placed rocks to prevent toppling, and ample swimming space. Providing hiding spots and ensuring the fish have the opportunity to dig into the substrate are essential for their well-being.
Behaviour
These wrasses exhibit a tendency to dig themselves into the substrate for sleeping or when feeling threatened. They are known for their hunting behavior, which involves foraging for food beneath objects. When introduced to a new environment, they may initially hide until they acclimate to their surroundings.
Feeding and Diet
Rainbow Wrasses require a diet consisting of larger crustaceans, small crustaceans like mysis and artemia, and other invertebrates. Their feeding habits may include hunting for prey such as pyramid snails.
Habitat and Distribution
These fish are indigenous to the Indian Ocean, ranging from the northern Red Sea to East London, South Africa, and extending eastwards to the northwest coast of Australia, including areas like Shark Bay and Green Island.
