How large is your tank, what is your lighting looking like? Your tank is still cycling so you have at least 3-4 months to go before adding an anemone (some may say 6 months at least). Not familiar with snowcassos, but I believe they are A. percula. Natural hosts for percs includes S. gigantea, H. crispa, H. ritteri, and S. mertensii. None of these are easy to keep however. If this is your first anemone than I would look into a bubble anemone or maybe even a LTA if you have a deep sandbed.
