Behavior

Filter feeder. Extends colorful tentacles to capture zooplankton from the water column. Stunning display animal. Requires excellent water quality and protection from aggressive fish.

Diet & Feeding

Filter feeder. Captures zooplankton and phytoplankton with oral tentacles. Requires regular additions of liquid zooplankton, phytoplankton, or Reef Roids directly into the water near the animal.

Cautions

EXTREME CAUTION: If a Sea Apple dies or eviscerates under stress, it releases potent toxins (Holothurin) that can kill all fish and invertebrates in the tank within hours. Never keep with aggressive fish. Requires pristine, stable water quality. Not for beginners. Have a plan for emergency removal if the animal appears distressed.
