⚠️ Important Information — Please Read First
We want to be genuinely upfront on this one. This species genuinely prefers live foods, especially when newly introduced, and can be a slow, reluctant eater that's difficult to wean onto frozen fare. Please plan for live river shrimp or black worms initially, with a genuinely gradual transition to frozen mysis shrimp, brine shrimp, and chopped seafood, and be prepared to target-feed after lights out if necessary.
 
📋 The Marine Betta, also known as the Comet or Comet Grouper, has a genuinely striking dark, velvety body covered in small white spots resembling a starry night sky, with a large, rounded, lobe-shaped caudal fin and a prominent false eyespot near the tail. Despite its common name, this species is genuinely not related to freshwater betta fish at all, simply sharing a similar body shape and long fins.
Native to the Indo-Pacific and Red Sea, this species is genuinely found in coral reef caves and crevices to depths of around 50 metres, emerging at night to hunt.
A genuinely remarkable, scientifically documented behaviour defines this species: when hiding in a crevice, it reverses in partway, leaving only its rear exposed with fins flared, closely mimicking the appearance of a moray eel peering out from its den — a real example of Batesian mimicry believed to deter predators. This is a genuinely hardy, disease-resistant species once established, though we want to be honest that it's a naturally weak swimmer, so gentle water flow matters, and it's genuinely shy at first, becoming bolder with time. It's considered reef safe with caution — it's safe with corals, but adult specimens will genuinely eat small fish and ornamental shrimp.
