i just bought some more corals for my ever growing colection. i got a very nice and big cup coral, branching hammer coral with 5 heads, candy cane coral with 11 heads, a different type of star polyp, and some red mushrooms. the candy cane and hammer is my first hard coral ever. so i am hoping all will be well.

i am just wondering if i have to feed the hard corals? or will just my 5 gallon water changes (i have a 75 gal) every 4 days do the job of putting what they need back into the water?

any answers will be appreciated.

thank's, jesse.
