Need some plastic frag plugs? Here are the Coral Cradles! No cure time and they work great in egg crate. Add some to your order and we'll put them in the same box as your corals. We have worked with Coral Cradle and have exclusivity on the color purple! These guys look GREAT. We chose a shade as close to coralline algae as we could get. Of course coralline comes in many different shades, but these guys blend in great.
