Care
Red-black triplefins are relatively easy to care for. They require a well-structured aquarium with plenty of rockwork and crevices to provide hiding places and mimic their natural habitat. A varied diet of small live or frozen foods such as brine shrimp, mysis shrimp, and finely chopped seafood will help maintain their health and coloration.
Reproduction
In the wild, Tripterygion tripteronotum exhibits a fascinating reproductive behavior. Males become territorial and display their vivid colors to attract females. After spawning, males guard the eggs until they hatch. In captivity, breeding is less common, but providing the right conditions can encourage spawning behavior.
Habitat
Red-black triplefins are typically found in shallow, rocky coastal waters, often in tide pools or just below the low tide mark. They are adept at navigating the complex terrain of their habitat, which includes crevices and overhangs where they can seek shelter and forage for food.
