The Slender Whitleyi Anthias is a popular fish among reef hobbyists due to their peaceful nature and attractive coloration. They are a schooling fish, so it is recommended to keep a group of at least six to eight individuals. These fish require plenty of open swimming space and live rock or coral for hiding and maintaining their stress levels. Overall, the Magenta Slender Anthias is an excellent choice for the home aquarium and with the right conditions, can be a long-term addition to any reef tank. Furthermore, they are quite hardy once acclimated and will not harm other tank inhabitants. Additionally, they can be kept in a community tank with other peaceful fish and invertebrates, making them a great all-around addition for the home aquarium.
The Slender Whitleyi Anthias is a beautiful, yet delicate saltwater fish that requires a specific aquarium setup to thrive. An ideal aquarium for them should be 55 gallons or larger and contain plenty of live rock for feeding and hiding. It is important to add them to the aquarium prior to the introduction of larger and more active fishes, as they should be the dominant species in the display. When housing them with other fish, only choose non-aggressive, relatively passive species. Otherwise, the Slender Whitleyi Anthias may continuously hide and not feed. It is also important to note that they should not be housed with larger, more active and aggressive Anthias species. With the right environment, these fish can make a beautiful addition to any marine aquarium.
Anthias species all share the trait of being hermaphroditic. This allows for the formation of stable social groups and the sharing of resources. If a dominant male perishes, the largest female of the group will often morph to take its place. Although because of the similarities in coloration, it can be difficult to tell the difference between the sexes.
