Green Mandarin Dragonets exhibit slow, deliberate swimming, often hovering near the substrate. They are generally peaceful, but males can be territorial, especially during breeding. Socially, they are best kept singly or in mated pairs due to male aggression. They are compatible with non-aggressive tank mates but may be outcompeted for food by faster fish. They prefer well-established tanks with abundant live rock for grazing on copepods and amphipods, which are their primary diet.
