In this video I discuss 4 corals that I was led to believe were great "beginner" or "starter" corals. Corals that were supposedly very easy to grow. However, little did I know, they would soon overrun my reef tank and make it very difficult to grow out my other more prized mini colonies. Come check out what 4 corals I am referring to and take a look at some evidence as to why you should NEVER put them in your tank!
