Can corals move?

Corals cannot move. They are immobile, and they are stationed in the same spot. They are able to reproduce by releasing sperm and eggs into the water to create baby corals.

Corals has no gender and they do not need female corals?

The ‘sex pattern’ for coral polyps is that about 71 per cent of them are genuine hermaphrodites: they have both sexes (male and female) in each polyp. But about 26 per cent are either male or female. And about 3 per cent have mixed sex patterns and/or they can swap sexes during their lives.
