Advice:The bigger and longer the tank the better. Good water flow and a opened aquascape is a must in order to eliminate dead spots. A deep sand bed (minimum 4"), good quality live rock, powerfull skimmer, and a properly set up refugium with Macro Algae can help keep nitrates at 0 PPM, and water changes to a minimum. Read all marine keeping books, especially "The Reef Aquarium" Vol 1, 2, and 3. Last but not least, Dont shy away from this hobby on the first signs of trouble. Marine aquarium keeping gets easier and easier as the tank matures. If trouble arises, internet forums can be of great help when questions need answering.
Advice:Feed 95% Seaweed sheets 3 or more times per day. Only feed silversides once per week for eel and grouper. ALL other fish eat Seaweed. ALL are extremely healthy, fat and growing inches each year. Almost NO fighting, just mild pecking order. Feed well and fish are happy. Whenever I add a new fish I dose the tank with Nitrofurazone once and let it run in tank for about 3 days and then water change out. I've had core group of fish now for 2 years. I try to keep phosphates low.

Advice:Read, research and plan. Be patient, don't over feed and always think like a fish. YouTube is a great source for info as well. There are some great artificial resin polymer corals out there. Ocean Aquaria and Rock n Reefs are 2 great suppliers
