I completely empathize with your desire for keeping an anemone and feel bad about your situation but I agree with everyone else...waiting until you have everything ready, including yourself, before attempting to keep an anemone will increase your chances of success greatly. As ccCapt points out, Sebae anemones require a lot of attention and careful planning, including a lot of light.
Speaking of light though, no matter what photosynthetic life you want to keep, whether it is anemones or corals, there is a lot more to the story than wattage. For this reason, it would probably help to know more about your entire system as a whole...for example:
- What are the dimensions of your tank?
- What are your long term goals (other than keeping an anemone) regarding having a reef tank?
- For example, are you interested in corals in general, or do you have some specific types of corals in mind?
- The reason I ask is because it is usually cheaper to upgrade once versus upgrading every other month like some people I know (i.e. myself )
- Do you have live rock in your tank and/or are you able to position future coral/anemone purchases closer or farther away from light as needed?
- What temperature does your tank water usually maintain?
- Do you need to use a heater or chiller to maintain that temp?
- Do you have any budget in mind....both in terms of money and in time? (i.e. do you really want corals now, or are you willing to wait and save up for a few weeks, months, or years?)
Of course, any other information about your current set up, as well as a description of what you envision this tank would be like in order to qualify as being "perfect" for you in the future would really help others help you make the best decisions and maybe even the best purchase(s).
