Sea Squirt (Polycarpa aurata)

Overview

The Sea Squirt (Polycarpa aurata), also known as the Golden Sea Squirt or Peacock Tunicate, is a vibrant, filter-feeding invertebrate prized for its stunning blue, purple, and yellow coloration. With its bulbous, vase-like body and vivid contrast, it adds a splash of natural beauty and uniqueness to established reef aquariums.

Origin

Native to the Indo-Pacific region, Polycarpa aurata is commonly found attached to rocks, coral ledges, and reef walls in shaded or low-light areas.

Feeding

A non-photosynthetic filter feeder that requires regular feeding of phytoplankton, marine snow, and other micronutrient suspensions. It relies entirely on suspended organic matter in the water, so a nutrient-rich environment and consistent feeding are essential.

Tank Mates

Completely reef-safe and peaceful. Best kept with other non-aggressive tank mates such as small reef fish, shrimp, and corals. Avoid predatory fish or those that may nip at sessile invertebrates.

Aggression

Peaceful and non-invasive. Does not compete for space or harm nearby corals or invertebrates.

Experience Level

Recommended for advanced aquarists due to its specialized feeding needs and sensitivity to water quality. Requires stable, mature reef systems with good flow and regular plankton feeding.
