I believe you have a severe case of reefers disease..it's a combination of mild obsessions...collecting of beautiful things, staring at a glass box for hours, reading endlessly on the internet (even at work), and OCD. there is no cure, no in between.
Seriously, if your tank is mature enough....one year seems reasonable, go ahead and add what corals you like. if these 'large' corals are wild caught, you will have less of a chance of succeeding. For some reason, a majority of them(wild caught) do not do well in hobbyists tanks. I suggest you keep the same mindset, but make a big effort to buy larger pieces from local reefers or aquacultured, even if it's at a slight premium, and you have to wait for the right opportunity to come along, verses impulse buying. end of the day, the name of the game is to not kill anything, or else your throwing $$$ out the window.
if you feel guilty about 'cheating', I musta already gotten my life sentence. I'm in the Marshall islands. I literally leave my back door, and go get whatever I want. corals, clams, fish, etc. the return policy is awesome as well.
since there's zero coral export from here, most of the corals are indigenous to this area only...stuff I've never seen in the states.
