To me that question indicates "not really". Corals are complex animals and require a very stable aquarium. You need to know all your water parameters, alkalinity, calcium, magnesium, phosphate, nitrate, etc... parameters should be stable for some amount of time. Light and flow should be adequate also.
You should google the different types of corals - soft, lps, and sps - and learn what each one needs to survive, then prepare your tank accordingly. When the light and flow and parameters match what the coral needs to survive, then the tank is ready. Google the beginner types of corals, there are hundreds of threads on beginner corals on this forum alone.
You got to do a bit of reading and have some base knowledge. Water testing and researching are very important to success with corals.
