There is maybe a 50/50 chance they may host it. Mine ignored the one I had and choose instead to host an expensive australian elegance coral, almost to death. I had to give the coral away to save it.
What type of nem did you get? They almost ALWAYS do best in an established system with pristine water and super lighting. What type of lights do you have? Do you have a liquid test kit, like the API one? You need to monitor more than just the Ph.
When I had my anenome I fed him every few days a piece of frozen silversides. A small piece too, you don't wanna give them huge chunks as they can have serious trouble with it. After a few days after you feed them they sometimes "ball up" which is their way of pooping. LOL
In the future, if you have any questions it's easy enough to start your very own thread as you will get more viewers. But I'm happy to help you with this here if the OP doesnt mind. ( and the moderators don't either) LOL
