I was wanting to get done soft corals. Are these advisable to get early on in a tank? What kinda of disease can they bring to the tank, infect fish and other corals? I read some people quarantine and others don't. The last thing I want to do is spend a month or more quarantine fish just to get them sick from a coral I bring in. Since I have fish in qt right now can I buy some soft coral and put them in my display tank now and the tank will be good to go by the time my fish go in?
