Safety: handling bubble coral

Low hazard

How do you care for bubble coral?

Placement

Sand or low rock, secured, as it is top-heavy typical, check

Flow

Low to moderate; strong flow tears the bubbles typical, check

Feeding

Occasional meaty foods

Growth

Slow

Water quality

Moderate

How much light does it need?

Sources put it at about 75 to 150 PAR, measured where the coral sits. No figure was published for this coral itself, so this is the usual range for its group. Start a new coral at the low end and raise it over weeks.

Shaded lower rockwork suggested. typical, check

Which neighbours are safe?

Night sweepers 7.5 to 10 cm typical, check

12 to 20 cm (5 to 8 in) typical, check

Take care (3)

These checks follow the reasons fish and invertebrates clash: same species or genus, similar shape, mouth size, temperament, food, burrows, tank size and the order they are added. Individual animals differ; every source agrees on that.

Pests, dips and quarantine

Few specific

Gentle dip; avoid tearing tissue

No dip reliably kills pest eggs, so a dip lowers the risk rather than removing it. Inspect new frags with a torch after lights out, including the underside and the plug.
