Can anyone suggest to someone just starting out which types of aggressive species should not be put together with non aggressive species? I don't want to purchase something exotic only to have it used as bait.
That is some useful information reeferlady. You must be really knowledgable about the subject. In another setting, the username "reeferlady" might be mistaken for something else entirely!
Busybee, Have you looked at the charts that reeferlady posted? They really are very detailed. Some aggressives can live well with some non-aggressives quite well.
careful with those charts not all species act the same. just have common scence when is time to buy. all depends on the environment like the tank space and how you set the tank(live rock ornament ect..)also their diet.
I highly recommend getting the book Marine Fishes by Scott W. Michael. You can take this book with you to the LFS and identify and choose fish with no doubt as to compatability and identification.

I didn't even think about it until you mentioned it. I'm not that knowledgeable, I just stumbled upon some info when I was researching what fish I should get for my tanks.
I thought it was as simple as you not putting small fish with the big fish. Because usually the bigger fish are more aggressive and could possibly kill the smaller fish.

Not even close. Damsels & dottybacks right off the top of my head are both small and HIGHLY agressive.
In this case size doesn't matter. Any size fish can be aggressive. I know they aren't saltwater fish, but Beta's aren't neccessarily large compared to other fish, but are highly aggressive, they can't be put in tanks with other fish including their own species.
