Info
These pycnogonids feed on the tissue of corals, similar to the related zoa-eating sea spiders. In this case it's however SPS they are after.
Oftentimes they are not really apparent during the day since they hide near or under the coral. One only notices the damage they cause on the corals.
They do not lay eggs but the males breed them and release fully developed small sea spiders. This is an advantage when fighting these animals: if you remove the adult siders you also remove the eggs.
There is no good in-tank treatment except manual removal - except one wants to try a wrasse or similar.
Prevention is quite easy: a preventative iodine dip makes sea spiders let go of corals and substrate.
