Seriously? Apparently you are misinformed because Frogspawn DO in fact have sweeper tentacles, and they normally extend in the evenings! Any site you look at will have it listed in the description! I.E.: Frogspawn Coral - Branched
The Frogspawn Coral is a large polyp stony coral (LPS) often referred to as the Wall, Octopus, Grape, or Honey Coral. Its polyps remain visible throughout both the day and night, resembling a mass of fish eggs or frog eggs, hence one of its common names Frogspawn. Its coloration is green or brown to tan in color. With its appearance and coloration it would make a nice addition to any reef aquarium.
During the evenings, its sweeper tentacles can extend up to six inches beyond its base into the reef aquarium surroundings. It will sting other neighboring corals in the reef aquarium, therefore, it is best to leave plenty of room between itself and other types of corals. It is moderately difficult to maintain, but it is a popular coral that will thrive under the proper conditions. It will need to have moderate to heavy lighting combined with moderate water movement within the aquarium. For continued good health, it will also require the addition of calcium, strontium, and other trace elements to the water.
The symbiotic algae zooxanthellae hosted within its body provides the majority of its nutritional requirements from photosynthesis. It will also benefit from additional food in the form of micro-plankton or brine shrimp.
I went back and re-read my previous post. And I now realise that I made it sound like I said that they have NO sweepers. My post was ment to say that they don't use the sweepers for feeding. While Euphyllias DO infact have sweepers, they are seldomly seen.
Most Euphyllias close up at night and don't sent out sweepers. They are mainly used as defence and NOT for feeding.
Euphyllias will only send out the sweepers when something is encroaching on it. If no other corals are within normal distance when it's fully inflated, it won't send them out. If you move something close to them, or if something grows into it's space, it is POSSIBLE that you could see them.
