Stylophora, The Other Stoney Coral

Stylophora, The Other Stoney Coral

Whenever speaking about stoney corals, Acropora and Montipora seem to always be in the spotlight.  And with good reason given the amazing colors nature has created in these magnificent animals.  But if you will indulge me for a moment, I would like to visit the other...

Why Acropora

Why Acropora

Every coral reef enthusiast starts somewhere when a reef aquarium begins.  Many start with soft corals and easier fleshy stoney corals with great success.  However I have found a trend in long term reef aquarists with many focusing on Acropora species as they advance...

Tabling Acropora Allure

Tabling Acropora Allure

The tabling Acroporas have that special allure.  One that comes to mind is  the ability to appear as if they defy gravity as they table outward.  The negative space visible under the colony and the brightly colored pigments on the plane that is exposed to strong light...

This Acropora recieves a 5 to 10 minute exposure to air on a weekly basis.  I have been experimenting with exposing the tops of one of my reefs to air during the weekly water change duty.  This is done on purpose and can easily be achieved without exposing the reef...

Captive Grown Beauty

Captive Grown Beauty

The amazing beauty of this Montipora capricornis can not be denied.  It was grown from a tiny seed fragment into this small colony in approximately one year.  This species and genus of stoney coral is a rapidly growing animal and adds mass quite quickly provided...

Pigment Grafting in Stoney Corals

Pigment Grafting in Stoney Corals

Pigment grafting has interested me since the first time my mind processed the concept. The theory basically involves the transfer of a pigment from one coral to another of the same species. The image above is a Echinophyllia aspera that was growing in close proximity...
