Info on coral
The TK Ultra Stag is an Acropora Staghorn - which actually only means that it grows branched. The exact species is not known. It was given the name 'Ultra' because its growth tips are very different in color from the rest of the coral. While the core is greenish to reddish in color, the tips are long and have a light base tone with red/purple counters.

There are usually several mother corals. To give you a better idea of what the offshoot can become, here are a few photos of larger corals of this species:

Unfortunately, you have to be patient with the offshoots. If you cut the coral, the offshoots first take on the base color and only show the light colors again when the coral starts to grow again.
