If you have enough light, feeding your anenomes will not be needed. They will get smal chucks of food at feeding time. What are you currently feeding? As for the light, it would be helpful to know the type and wattage you have. Are you using the single light strip that probablly came with the tank? If so it is most likely NO
flouresent light. It is not enough to support an anenome long-term. If you do not upgrade your lighting, they will die. You will need at least 4-6 watts/gal
or even MH
lighting to keep them going.
