I went to the LFS looking to pick up a clown fish but they didn't have any left - so I took home frags of torch and hammer corals. I have a 30 gal tank with 285 watts of VHO lighting. Where should I place them? The guy at the LFS said they would do OK low in the tank. Right now, I have the torch on the sandbed and it is expanding nicely. The hammer is still shriveled up. How much current will they like? Will they hurt each other if they touch or is it only with other species?
