A well-mounted frag grows; a loose frag tumbles, gets stung, and dies. Three techniques cover almost every coral mounting situation.

Cyanoacrylate gel

Best for SPS frags on plugs. Apply a pea-sized blob, press in place underwater for 20 seconds.

Two-part epoxy

Best for LPS and large softie colonies. Knead until uniform color, press into rockwork crevices.
