Okay so I am purchasing a 150 gallon tank in about 6 months (taxes yeah!). I am having the common problem of figuring which direction to go. I know a lot about fresh water fish but almost nothing about salt. I have been looking up a lot of fish that I like but keep running into the problem of them being incompatible or too difficult to keep (mandarins.....so sad, cool fish). So I need a generalization here. Is it generally easier to keep aggressive or non?? I should say which is hardier? If it helps I know I am going with a fish only tank. I do not want a reef tank. Any assistance would be really helpful.
