not too hard,but just most likley all anemone will die in max 2 yrs,if u want some long term corals, should go for some more hardy coral such as polyps or zoaths
even some of the LPS
works fine.Oh, sometimes clow will search for diff type of coral to host such as mushroom which is another great hardy coral and mushroom actrually quite good looking sometimes(of course the price will be high sometimes also depend on the coloration).But trading for another anemone in 10g is always an bad idea, unless u really don;t care ur "pet" die or not.To me I would rather spend time try to keep wat i have alive instead treating them as pure decoration.
EDIT: I might sound harsh soometimes,but really its the truth, I jusy hope most people getting in SW
know what they are dealing with and whats the out come of some of their decisions.
