its stronly discuraged keeping an anenome in a tank let alone in a small tank and it being your first saltwater tank. Anenomes can live decades (estimated) in the ocean but many strugle to live longer than 1 year in an aquarium.
For an anenome I would say lighting in the range of 5W+ per gal
. So for a 10 gal
tank at least 50watts of actinic and 10K specitrum.
For many soft corals you can get buy with less light. On average I would shoot for 3 - 5 watts per gal
With out a filter you need plenty of live rock (for a 10 gal
tank i would shoot for 15lbs of LR
) and a sand bed of 3-4" in depth.
For water movement you can use power heads.
Dont forget a heater to keep the tank at 80F or there about.
