Why do you guys atempt to answer question with made up bull shiat?
Anemones of ALL species contain zooxanthellae algaes. Thes are light loving cells that produce food via processing light into food for the anemone.
Most ALL anemones in the hobby today save for conylactis and hatian's are ALL AQUACULTURED SPECIMENS.
If you would like to keep and anemone you should know three things up front.
one: they will move until they are comfortable, stinging every thing in there path.
Two: They require FEEDINGS OF MEATY FOODS as well as strong - medium light and flow.
Three: They will only survive long term in a matured aquarium. With VERY good, stable water quality.
Bulb tipped anemones are pretty easy to keep as long as you have the correct wattage and feed them regularly in a mature tank.
They split often when they are happy producing more baby anemones.
Carpet anemones are harder to keep as they require heavier feedings and alot more room.
Same for Crispa's.
Seabae anemoes are a little harder to keep as they are more tepmermental.
Hatian and condylactis and VERY easy to keep.
Tube anemones are light loving but easy to keep.
Ricordea mushroom anemones as well as antidiscoma, and discoma mushroom anemones are also good choices.
Curly Que anemones are to be avoided though as the have VERY long tenticles that can reach out in a 1 foot diameter.
Flower rock aneomes are an EXCELLENT choice for begginers as well.
A Clown will host in a carpet anemone, a seabae anemone ( which is very picky with water quality to BTW) even seen them host in BTA's, ricordea, hairy mushroom anemones. ect ect ect.
There are 100's of species of anemones for you to choose from.
My advice to you is to chose one with more less demanding needs, such as a hatian, or condylactis to start out with, or even a Flower Rock anemone, Also plann on dedicating the tank around the anemone instead of ploping one in there and hoping for the best. As I said they will move and kill of what is in there path more times than not.
Never mind the bs posted above and do your own home work if this dosent suffice.
Any one with the slightest knowledge or coral can tell you most all bta's carpet's and ricordea as well as most ALL other anemones are propogated now.
Its a matter of a simple google search.
"did you know that anemones are taken from the sea to be placed in an aquarium?" No shiat! Its called introducing wild strains for captive breeding.
LOL!!!!!
I would DEFINATELY upgrade you rlightin gto a 96w power quad for any anemone you plan to keep in your 10g too.
