Could anybody perhaps tell me how to keep control of pulsing zenia's? They are really beautiful, but they are starting to take over my tank and I would like to bring them under control before they smother everything in my tank.
Frag viciously and swap out for stinging coral which you can then place in amongst them to subdue their growth!
But generally they like a nutrient rich system.
Oh and yes, frag by simply cutting off the rock with a sharp blade or pointed tip scissor, try cut just beneath the surface they're attached to so it makes easier for you to mount to new rocks/plugs. Good luck
