Is a Green Slimer a Good Starter SPS?

Green Slimer
Though the classic green slimer isn't the SPS I recommend as your first (I think birds nest are much easier) they are most certainly the one I recommend for the first acropora (pronounced a-crop-uh-ruh and not acro-pour-uh). The name comes from just what you would expect, a slimy coat of mucus the coral excretes. You will get quite a bit of it in the bag when you get your frag home. Because of thi...

This study highlights a very important truth in reef keeping. Every...

Coral Fighting and How it Affects Placement and Purchase

Corals Fighting
Corals are vicious animals Many people still don't know that corals are animals, alive and adhering to the Darwinian principle of survival. Since Victorian times, or perhaps even before, many corals were confused for plants. To this day I sometimes have trouble getting guests to comprehend that they are alive. But this fact is vitally important to the aquarist. Corals are downright violent and wi...
