BTA queries

[turkleton]

I don't really care if there is much else in the tank, a pair of clown's and an anemone are about all i'm looking for. I would maybe try a couple soft corals as well but nothing much, a few mushrooms maybe. Although I really like maroon clowns I would go with something smaller and more docile. I had a pair of maroons in my 65 when I initially set it up but when they got big enough they turned into quite the pain in my ass, especially the female. She would regularly attack my hand and knock over corals.

I've had this 33 gal set up for about 3 yrs. Lighting is 4 24w T5's.At one point there were 8 BTA's. It seems when it gets too crowded they move off the area at the left. I have my powerheads covered so there is not too much damage if they do.I have a HOB refugium with chaeto and a CPR protein skimmer.The main flow is one of the smaller tunzes.There is aquaclear powerfilter for chemipure elite.
Initially I had a tomato clown and a cinnamon . The cinnamon was larger and in the tank first. As the tomato grew,the cinnamon no longer tolerated him so he had to be removed.(they did have a couple of sets of eggs though).
After the 15 yr. old cinnamon died I replaced her with 2 percs. Since there was not much else in the tank for them to call home they took to the BTA's within 3 days.
Corals include,GSP,mushrooms,and leathers.There is now also a green goniopora,chalice and acan.
I think your 20 gal would be fine.

I forgot to say the tank is 22 inches tall and the anemones stay at the bottom so your 16 tall should be good.
