New to clams, advice needed

[Dwarfpufferfish]

I am setting up a 65 gallon ALL Zoanthid tank. I am considering adding a clam or 2 to the substrate! What is a good calm (smaller is better) to have in my set up~

Lighting will be 2x175 watt MH 10,000k, 2x96watt actinics.

Also what fish are good companions??

Squamosa and Derasa if your plans are to keep them at the bottom(sand).Maximas and Crocea can be place into the rocks(closer to the lights) For fish IMO any clown/tang, in my case I have a Flame and a Pigmy in my 75 knocking on wood no issues with my clams/LPS:D
