 Almost speechless.
I wouldnt use the ammonia remover, it may affect the bacterial populations which you will need to keep the ammonia in check. Nitrates arent a huge issue for the fish, but for the anemone they could be a problem. This tank really isnt appropriate for an anemone.
I think the fish stocking is going to be a problem in the long run when the fish grow up possibly even sooner. Thats alot of fish for a 120g tank.
