the info you are getting is helpful. First off, and not trying to sound critical, you don't even know what kind of anemones you have. Condylactis and some other rock anemones will do okay under moderate even low light. Most reef anemones and bubble tips and carpet anemones need very strong lighting to survive and thrive. The truth is that your lighting is not considered to be very strong. Compact fluorescents are bright but do not provide much PAR (photosynthetically active radiation) in deeper tanks. Your anemones may do okay for a time, over time they could lose their colors or more likely become a dull brown color.
Be cautious of any filter intakes or powerhead intakes and cover them...anemones move and often a powerhead intake is all it takes to kill one.
If you are truly interested in keeping mainly anemones, I would search around for some books that deal mainly with their husbandry. I don't keep any anemones and I'm not familiar with any books off the top of my head.
In the mean time, try to keep the water quality pristine, anemones do not tolerate high levels of nitrate. Try feeding the anemones with pieces of krill or silversides..have they been eating since you've had them. Look through some online retail sites or post a pic if possible to get a better ID
and some more specific advice.
