2 cynarina almost touching ok?

[pitmindi]

Hi, does anyone know if 2 cynarina corals can be placed within inches of each other? I just got a red one and a green one and placed both on rocks on the sand (so they are not irritated by the sand) and they are with in 2" of each other when expanded. Thanks

I have had a couple of cynarina before. Placing them next to each other touching with no problem. Only concern I had at first was "Will their feeding tectacles touch and kill each other?" Found out, at night when they have their feeding tectacles out, they are only half the size when they were fully open at day time. So their feeding tectacles never touched each other.
