Slow growing soft corals

[cristata.reef]

Blue Green Sympodium...i find dont grow rampantly fast

I think it depends on the tank. Mine spreads kinda fast. A quarter sized frag became the diameter of a golfball in under 3 months. Then again, I do feed them an have them in high light

What are some slow growing soft corals?
In other words what corals will take more than 6 months to a year to cover over a rock and wont overgrow everything in a tank?
