I have small colonies of favia (or favities), brown
variation taken from the seashore of Florida Keys... They look nice, dark brown with polyps extending from the rocky ball of their skeleton... They are doing fine without target feeding, but I have heard they could benefit from feeding zooplankton during night - they hunt plankton with sweeping tentacles. I have inspected these corals at night with a flashlight and I have never seen any sweeping tentacles... Here is a short movie of the coral taken during the day just to show you what coral I am really talking about: http://www.darmoland.com.pl/pszemol/...6/Favites1.avi http://www.darmoland.com.pl/pszemol/...6/Favites2.avi (it might not play directly from the link - then save the file on your local machine and play it from there...) So my question would be: anybody here has this or similar coral in your tank? If so, do you observe sweeping tentacles? Do you have any pictures of them to share with the group? |

I'd have to say that the presence of the food will bring out the feeding behavior. |

I have inspected these corals at night with a flashlight and I have never seen any sweeping tentacles... I had my favia for over two months befors I saw tentacles extended. Maybe they're just slow waker-uppers. -- Toni http://www.cearbhaill.com/reef.htm |

Where did you hear this; "I have heard they could benefit from feeding zooplankton during night - they hunt plankton with sweeping tentacles" I have heard and seen statements similar to his but just assume that don't understand the real deal about sweepers and are just assuming they are lookin' for food Sweepers are for defense, fighting and attacking other corals. Why would there be a need for sweepers to do this, when the regular ever day tentacles do this ? They are not out as they sense no near-by threat to be out. They also are not structured right to catch food. It is like you trying to catch a fly with your hand while your whole body is covered with sticky fly-paper :-) You might like this bud http://www.reefkeeping.com/issues/2003-09/rs/feature/ http://www.biolbull.org/cgi/reprint/179/1/96.pdf -- Boomer Want to talk chemistry ?

Where did you hear this; "I have heard they could benefit from feeding zooplankton during night - they hunt plankton with sweeping tentacles" Looks like I made old mistake of listening to wrong people :-) I am new to SPS and instead of reading stuff in a reputable sources I trusted one of my "all-knowing" friends who has reef for 5, maybe 7 years :-) When do I learn not to do it ? ;-) I have heard and seen statements similar to his but just assume that don't understand the real deal about sweepers and are just assuming they are lookin' for food The thing is I tried to feed my favities and they do not accept zooplankton... How can I stimulate them to eating ? What food ? Sweepers are for defense, fighting and attacking other corals. Why would there be a need for sweepers to do this, when the regular ever day tentacles do this ? They are not out as they sense no near-by threat to be out. They also are not structured right to catch food. It is like you trying to catch a fly with your hand while your whole body is covered with sticky fly-paper :-) I see... sometimes, when I feed my hermits with some pellets some of them land on the coral and stick to it... I am not sure if coral can benefit from this kind of food, can it ? You might like this bud http://www.reefkeeping.com/issues/2003-09/rs/feature/ http://www.biolbull.org/cgi/reprint/179/1/96.pdf Thanks - I will read it tonight. |
