Woah, 2 anemones and 1 urchine all in a 10g?
how long did ur frd keep that tank before giving it to you?
I would say 10g is too small for any anemone except those that too small for any clown fish to host.
Anemone need space to walk around and adjust to their best location to feed or getting enough light.
If you really have a condy ( not sure cuz i can't find the anemone as u type out in search engine). They need strong light a sinple 30watt NO
might not be enough for it , u need at least 4.5watt-5watt per gallon if u really want to do some calculation.
On the other hand, condy donnot or rarely host clown fish of any kind. It is possible to keepa pair of small percula in the tank but i will not put too much hope on they might host the anemone. To a beginer I would only suggest BTA as the starter anemone if u MUST include one in ur tank and want to see the great relationship between them and the clown fish.Otherwise I will not even try to keep the anemone especially in a 10g tank.
One more thing,Ur urchine might starve to death later cuz not enough LR
which will lead to not enough algae and not enough hiding place for it.
