Hi Brandon.
Did you determine WHY the first one died before you got another one? If not, please PLEASE ask questions before buying another one of *anything* that doesn't make it, before buying more, and better still, PLEASE ask questions BEFORE buying.
Having said that, you have an anemone now, so let's try to help you keep this one alive.
FIRST of all, if you have any powerheads or intakes that do not have sponge prefilters on them....COVER them with foam ASAP. More anemones die from getting sucked into filtration or circulation devices than probably anything else....despite warnings to take simple measures to prevent it. This animal will wander around until it finds a suitable place that gives it proper light, and proper water flow, and depending what type of anemone it is, it might bury its foot in a crevice or in the sand. Do not interfere with it, unless it's in harm's way. Anemone-proof your tank as I mentioned by covering intakes.
Next, you need good lighting. Tell us about what kind of lighting you have, wattage, type, etc.
Also, it's recommended that you feed the anemone with meaty foods, at least once per week, more if your lighting isn't up to par. Chunks of squid, clams, silversides, etc. that have been thawed and (optionally) soaked in vitamins such as Zoecon or Selcon are good choices.
Hope this helps.
