Running out of space to put new frags, but don’t want to remove or trim back other corals in order to make room? If restructuring your live rock layout is also impossible, then do what most cities do when they get overcrowded, go skyward. Instead of having to rely on a small empty space on the rocks, if you can find it, glue a frag to a magnet and move it up into the water column a bit. There are product specifically designed for this, or you could use an old algae magnet or leftover powerhead hardware. The possibilities are endless, and you can move the coral to wherever you like. Just keep in mind that down the road, the coral may overshadow whatever lies beneath it.
