Back for more great advice.

I have two tanks one 150g set up since December08 and a 180g set up 1 month both tanks read Amonia 0, Nitrite 0, Nitrate 0, Calcium 420, KH 8 in the 150 and KH 10 in the 180. The 180 is a used tank that came with very mature rock and water but I am using new sand and has upgraded lighting so has some brown algae on the glass.

I have been considering getting a rbta but have had a hard time finding a nice healthy one. Today my store had a beautiful long tentacle and a carpet anemone. I could get a good deal if I took both and I had planned on a carpet later in the 180.

So questions, are long tentacles more difficult to keep than an rbta? Is my 180 too new to meet the needs of a carpet? Any thoughts?
