So far I have learnd that there are 2 typs of coral. But I dont know what they are called, nor Do I know the differnce. whats the differnce between them? are the only two types soft corals and hard corals?

Is one coral, one animal, or does a coral consist of many types of animals in one block thing?

I am very new at this. I dont even know where to begin. People online keep saying do research and read on forums...however, I dont know where to start other than by asking qustions.

I need help on learning things like....what a coral is...to the "anatomy" of a coral...to "feeding" a coral...to takeing care of them...learning all the biology behind them...what they are compatible with....why they have difernt colors...how to atach them to live rock...if thats what your suposed to do with them?

I just orderd my new custom made sump today. Im buying a Skimmer tomrrow...I have the 14 K lights...Im planning on buying a calcium reactor soon...So, I have all the equitment, but that is not going to do me any good if I dont know what im doing...I just know that i pretty much have everything I need to HAVE reef tank, except, i dont understand THE part of a reef tank...corals.
