LOL! I wish I could frag my purple haddoni for you!

Hummm... tough decision but I would only put a carpet in either the 55 or 75 gal tank because they get HUGE. The 75 gal has the strongest lighting so I would have to vote for that reef. Yes, they eat fish but only fish that run into them. Beware that they might also 'walk' around the tank until they find a spot THEY like. I've had mine to walk a lot but it never killed anycoral.
Keep in mind haddoni anemones like a lot of flow, low/no nitrAtes, strong light (MH) and a sandy bottom with adjacent rocks to hide their foot in. Mine has its foot wedge in the sand between two rocks.

The polymnus will find it within a day and the sixline will stay far away from it then.... or else... lol
