SPS Question

[Stones]

Typically, maricultured SPS are produced from frags originating from wild caught colonies and then grown out to a specific size in large frag racks located in the ocean. Maricultured SPS colonies very often do much better and adapt faster to life in the aquarium than do wild caught colonies. Maricultured SPS also significantly reduce the impact of harvesting corals from natural coral reefs so thats another benefit as well. Wild caught SPS colonies typically do not fare well in the aquarium and commonly suffer from RTN(rapid tissue necrosis) and STN(slow tissue necrosis).
