If the FH population is doing well and you are going to use it as a forage pond then leave it as is. Feeding a few pellets would help grow the FH and good spawning structure would help also.
You should give them a salt bath before putting them in another pond.
I bet the dark stripe becomes more obvious when spawning starts. Check and let us know.
