Care
Delta Chromis are relatively easy to care for, making them suitable for both beginner and advanced aquarists. They thrive in well-established aquariums with stable water conditions and plenty of swimming space. These fish are omnivorous and will accept a variety of foods, including small pellet and flake foods, as well as frozen and live meaty foods like mysis shrimp and brine shrimp.
Reproduction
In the wild, Delta Chromis reproduce by releasing eggs and sperm into the water column, where fertilization occurs. In the aquarium, breeding can be a challenge, but with optimal conditions and a well-maintained environment, it is possible to observe spawning behavior.
Habitat
Delta Chromis are found in the Western Pacific Ocean, where they inhabit coral reefs and lagoons. They prefer areas with strong water movement and are often seen in groups hovering above stony corals or branching corals.
