Safety: handling birdsnest coral

Low hazard

How do you care for birdsnest coral?

Placement

Mid to upper

Flow

Strong but indirect; a direct jet snaps thin branches typical, check

Feeding

Takes a range of particle sizes typical, check

Growth

Fast

Water quality

Hardy if parameters are stable typical, check

How much light does it need?

Sources put it at about 150 to 400 PAR, measured where the coral sits. Start a new coral at the low end and raise it over weeks.

150 to 300 in one guide; 200 to 400 in another. typical, check

Which neighbours are safe?

Low

Room; branches are brittle

Fish

Fish known to nip this group of corals, or small enough to be caught by it.

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

Red bugs possible

General SPS dip

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.
