Do Maroon Clownfish absolutely need an anemone to survive?

No, they do not require an anemone to survive in a home aquarium. However, providing a Bubble-tip Anemone (*Entacmaea quadricolor*) encourages their natural symbiotic behaviours and provides them with a sense of security.

Why is my Maroon Clownfish biting my hand during water changes?

Maroon Clownfish are fiercely territorial, especially mature females protecting their host anemone or a clutch of eggs. Biting is a natural defensive response to what they perceive as a large predator invading their space.

Can I keep two Maroon Clownfish together?

You can only keep them together if they are a bonded pair. Introducing two random adults usually results in extreme aggression, leading to the severe injury or death of the smaller or weaker fish. It is safest to purchase a pre-bonded pair or introduce a tiny juvenile to a resident adult.

Can I mix Maroon Clownfish with Ocellaris or Percula Clownfish?

No, this is highly discouraged. Maroon Clownfish are the most aggressive of all anemonefishes and will almost certainly hunt down and kill other clownfish species sharing their aquarium.

Why does my Maroon Clownfish have gold stripes instead of white?

The Gold Stripe Maroon is a natural geographical variant primarily found around Sumatra. The stripes begin white in juveniles and gradually turn a vibrant yellow or gold as the fish matures.

About the Maroon Clownfish

Historically classified in its own genus (*Premnas*), the Maroon Clownfish has recently been grouped into *Amphiprion* by many modern taxonomies. It is the largest and arguably the most formidable of all anemonefishes, characterised by a deep maroon body crossed with three stark white or vibrant gold stripes. Unique among its peers, it possesses prominent preopercular spines on its cheeks, earning it the alternative name of Spine-cheek Anemonefish.
