4 - fish: C56B14 / R2356 noting B25 and C56 locking 2/4 candidates as true:
when 5A is true the strong links setup a 2ndary 5A as true, leaving 5a cells as an X-wing {also note that it implies 5B as false}
when 5A is False then 5B is true and the strong links setup a 2ndary 5B as true leaving 5b cells as an x-wing
all common cells of 5a x-wing and 5b x-wing can be removed.
interesting to note is that the only spot this occurs in also house 2 of each 5a,5b set.
coincidence don't think so.

hypothesis rule:
when a fish has multiple sectors that are Bi locals and these locals are peers of other bi local sector, then the fish has at least 1 digit locked into n-1 sector
when this occurs
any Sector that has >=( N - 1) fish cells in a sector that sector can only hold the fish , all other cells of the sector <> fish digit.
