I am new to coral and a little nervous about taking care of them. I just bought a bunch of different coral from a guy tearing down his tank. I don't know the names of the coral, but I have always loved the way they bring your tank together. I know that I bought a lot of soft coral, and the guy said I don't feed them that they get what they need from the lights. Is this true? Any help would be appreciated on how to take care of them. I have a 180g with 20g sump that I have used as a fish only tank for about 3 years (though it looks about empty because I only have a picasso trigger, lemon peel angel, and a snowflake eel and red mangroves). I recently obtained a reef breeder LED light, and have a 48" T5HO with 2 atinic and 2 white.
