palys, benign. Not really a fast grower/spread.

[leebo_28]

safe though?

I agree that they are palythoas. I have a couple that grow like crazy and a couple that grow real slow. They are safe. I have a bunch mixed in with my zoanthids.

Here is some information liveaquaria.

"They are very easy to maintain in the reef aquarium. Their polyps have the ability to sting other animals and are semi-aggressive, therefore, they need to have space between their colony and any neighbors. They also grow rapidly and will crowd out their neighbors including any sessile life. They require a medium light level combined with a medium to strong water movement within the aquarium. They will reproduce easily in the reef aquarium by budding (splitting off a portion of their base or mouth), which will increase the size of their colony. For continued good health, they will also require the addition of iodine and other trace elements to the water.

The symbiotic algae zooxanthellae hosted within their bodies provides the majority of their nutritional requirements through photosynthesis. They benefit from weekly feedings of micro-plankton or brine shrimp which should be fed to each individual of the colony. "

yes, benign. They do not roam around and kill other inhabitants. Their tentacles are used to hunt prey. As such, any drifting food that touches them will be eaten. But that does not make them virulent. LPS use the same mode of feeding. They are often seen amongst colonies of zoos.

double post

thanks for the info and ID guys/gals! So I will need to feed each one a brine shrimp(sea monkey??)once a week?

[AquaReeferMan]

What kind of lighting do you have? If it is enough than you dont have to feed them. They will sometime catch some food in the current but thats it. That was a little crazy, I didnt relize they said feed every singel polyp. If that were true I would have to target feed about 500 polyps/week.

lol...I see.....I have 2 20 watt 50/50's over a ten gallon with homemade reflector and canopy. a homemade overflow with a mag 5 as a return. Temporary fix til the 90 is complete :)

[leebo_28]

oh...30 gal sump with rubble and cheato also

[AquaReeferMan]

Yeah they will be fine. If they are spreading now then you dont need to change anything.
