LPS Coral
Green Pearl Bubble Coral.
An LPS (large-polyp stony) coral whose grape-like bubble vesicles inflate by day to a soft green glow, then retract at night. Best for an intermediate reefkeeper — it wants gentle, indirect flow (strong current tears the bubbles) and moderate light, with room to expand.

Live animals are sold in store only — we do not ship fish, coral, or invertebrates. Every animal is acclimated and health-checked in-house before it reaches the sales floor. This is a species we carry — it's most likely in the tanks around delivery days, but live stock changes daily. Please call (814) 456-9445 to confirm availability before you drive in.

Good tank mates
A large-polyp stony coral that inflates pearl-like vesicles by day and extends long, stinging sweeper tentacles at night, so give it wide clearance from all other corals to avoid stings. House it with peaceful reef-safe fish and invertebrates, but avoid coral-nipping fish and keep aggressive neighboring corals well out of reach of its sweepers. Pearl bubble corals are closely related to bubble and anchor corals and can fight with them, so don't crowd them together.
Good to know
Pearl bubble coral inflates its bubble-like vesicles during the day to soak up light, then deflates them at night to deploy long sweeper tentacles for catching food and defending its space.

Firefish Goby
Universally reef-safe and thoroughly docile. Does not nip at or disturb LPS tissue. Confirmed safe with fleshy LPS corals across multiple care sources; its skittish, hover-at-cave-entrance behavior means it spends no time near substrate-level corals.
Royal Gramma
Rated 100% reef-safe by all major sources; ignores corals and large invertebrates entirely. Territoriality is directed at conspecifics and cave rivals, not at corals. Stays in rockwork, well away from a bubble coral placed on the sandbed or lower rockwork.
Banggai Cardinalfish
Confirmed reef-safe; will not graze on, nip, or disturb sessile invertebrates or LPS tissue. Slow-moving and planktivorous in captivity, posing no physical threat to the coral's delicate vesicles.
Green Chromis
Planktivorous water-column feeder; does not nip corals. Multiple reef-keeping sources confirm it is fully coral-safe. Intraspecies aggression (establishing a dominance hierarchy within the group) is the only documented aggression and is irrelevant to coral safety.
- N
Neon Goby
A cleaner fish explicitly rated safe with soft, LPS, and SPS (small-polyp stony) corals. At max 2 in. and focused on ectoparasite removal from fish, it has no behavioral or dietary reason to interact with bubble coral tissue.
