Lps corals are very easy to take care of, that is if you can keep water in your tank. They are beginner corals, not saying experts don't keep them, but they take a beating and keep going. Yellow torch corals are the expensive torches because they take a lot longer to reproduce. If you want to feed them because it gives you that fuzzy feeling in your heart, then feed them but it isn't a requirement. Low to medium flow and low level in your tank. They will tell you where they want to be on how extended they are.
