They filter feeds more so than excepting solid foods IMO. I do give them a little brine shrimp juice or a formula 1 cube about a couple times week and they have been going strong for 2 years. I would keep a pretty close eye on the condy though because my $6 condy is now worth about $150 from all the fish/inverts that it's stung to death or eaten. I ended up having to remove it. Also you want to make sure you have enough light for them as well as they harbor zoolante and get a lot of their nutrion from symbiotic alga. also make sure you have good water quality to assure the success of these beautifull animals. You did make a very good choice for a first anemone they are very hardy ,"for anemone."
