Upside Down Jellyfish

(Cassiopeia sp.)

Cassiopeia jellyfish are found in warm coastal waters, particularly in shallow lagoons, bays, and mangrove areas of the Indo-Pacific region. These Jellyfish typically rest upside-down on the seafloor, exposing their photosynthetic algae (zooxanthellae) to sunlight. This behavior allows them to maximize their exposure to light and nutrients for mutualistic symbiosis with the algae. It's essential to avoid using copper-based treatments in a tank with invertebrates, as it can harm them. Always follow the recommended guidelines for medication use in marine aquariums.

Cassiopeia Jellyfish are commonly referred to as Dwarf Cassiopeia or Upside Down Jellyfish. They are occasionally collected for the aquarium trade. The coloration of Cassiopeia Jellyfish can vary but often includes shades of brown, green, or cream. They may have mottled patterns or other markings on their bell, which can help them blend in with their surroundings. They can grow to up to 1'.
