Clove Polyps

[Sean]

Hey,

Does anyone have some tips or tricks for these little guys, I made the mistake of impulse buying them thinking they would be as hardy as regular polyps or zoo's but it seems they are a little more tricky.. I increased my light time in the tank for them and a few heads are starting to come out. Its only been a week so i'm sure they need time to adjust.. I guess my main question is do they just feed off plankton and light.. or should I be adding something in there for them.
