I don't think you need to put either in the tank if it is still cycling. In fact, I'm told that you should wait at least 3 mos to even think about an anemone. I have had my 50 gal
tub set up for 10 years.... water checks out fine... 36" strip of LED
lights (reef capable). My $60 beautiful long tentacle did great for @ 1 wk then just shriveled up and died... very, very depressing... for me & for the clown that loved him so
They also tend to do this at the most inopportune times ... I was going out of town for the week-end... trying to decide whether to take him out or leave him in.... just in case he was just "being an anemone"... they do strange things. Anyway, he ended up dying.... I now have a very pretty plate coral and my clown has hosted in him and seems pretty happy. ... not as excited as he was with the anemone but happy.
