Bubble Coral Care Tips

Welcome to Zeo Box Reef Aquaculture, your trusted source for high-quality Bubble Corals (Plerogyra sinuosa) and other similar species. Bubble corals are a favorite among reef aquarists due to their stunning beauty, relatively fast growth, and adaptability to various aquarium conditions. Despite their delicate appearance, these corals are remarkably resilient, making them an excellent choice for both beginner and experienced aquarists.


Physical Characteristics

Bubble corals, scientifically known as Plerogyra sinuosa, feature unique tentacles that have transformed into bubble- or grape-shaped vesicles. During the day, these vesicles expand and display an array of colours, including white, brown, bluish grey, green, or fawn, often adorned with an attractive "fingerprint" pattern. At night, the vesicles contract, and longer "sweeper" tentacles armed with stinging nematocysts emerge to aid in feeding and prevent neighbouring coral colonies from encroaching. The coral's skeleton, which is mostly hidden when the bubbles are inflated, possesses sharp, blade-like septa lining the top edge. The vesicles are directly attached to these septa. Finding a secure spot for the irregularly shaped bubble coral can be a challenge, requiring careful placement to prevent toppling and ensure the vesicles do not chafe against live rock. Adjustments to your tank's rockwork may be necessary to create the perfect niche for the coral.

It takes a lot to kill them

Bubble corals are surprisingly tough despite their delicate appearance. They can withstand minor accidents and recover quickly. Even after a tumble down the rockwork and landing upside down, these corals have demonstrated their resilience by fully re-expanding their vesicles within a few hours, showing no signs of damage.


While bubble corals can handle some rough treatment, it's important to note that they may not always survive severe abuse. Rough handling during collection, transport, or introduction to the aquarium can cause lacerations on the coral's tissue, making it susceptible to infections. To minimise the risk of damage, consider placing the bubble coral at the bottom of the tank with its skeleton partially buried in the substrate. However, avoid areas prone to detritus accumulation. If you notice sand or debris settling on the coral, gently lift it by its skeleton, invert it to dislodge particles, and then carefully place it back in its spot.  

Tank placement

Bubble corals are adaptable to a wide range of lighting conditions in the aquarium, as they are found in both turbid and brightly illuminated areas in nature. You can position them at different levels in your tank, taking care not to expose them to excessive light intensity right away. It's advisable to start with a lower placement and gradually move the coral upward, allowing it to acclimate to the specific lighting conditions of your tank.

Sweeper tentacles

Bubble corals have sweeper tentacles that, while not as long as those of other corals, still possess stinging capabilities. To prevent irritation or injury to neighbouring specimens, maintain a distance of approximately 15 centermetres between the bubble coral and other corals. If you observe neighbouring corals refusing to extend their polyps or signs of tissue damage facing the bubble coral, it is essential to relocate either specimen to a less volatile location.

Water Movement

Moderate water movement is beneficial for bubble corals. The gentle swaying and jiggling of the vesicles help keep them free from debris. Avoid direct blasting of powerheads onto the coral, as it may cause

Can I expect the coral I see online to match what I receive in my order?

Shopping for live coral for sale online can be a source of worry for reef hobbyists, who can never be entirely sure what will arrive in the mail. Will it resemble the coral they saw online? While there is no substitute for an in-person viewing of the coral, we offer What You See Is What You Get (WYSIWYG) corals to alleviate concerns. Our WYSIWYG corals allow you to preview the actual coral fragment or colony before making a purchase. We take pride in photographing all our corals under Ecotech Radion G5 LED Light fixtures. We use professional-grade Full Frame DSLR cameras and lenses to capture the highest quality representation of the coral. We also provide multiple photos of the coral under different light spectrums, including full spectrum (white light) and heavy blue spectrum. We also offer size approximations for every coral in centimeters. This measurement is taken when the coral is fully expanded, providing you with a better understanding of the amount of space the coral will occupy in your aquarium.
