so I did my 1st freshwater dip today that was unnerving. It took 45 min to catch the sucker from the tank 1st off. He needed a "factory reset" anyway.. he was getting way to aggressive with the other tang so into a QT bucket he went and then I rearranged the rock a bit. Then the freshwater dip. I'd be lying if I didn't say I was freaked out. 2-3 min then back to qt bucket. Yep saw "sesame seeds" in the freshwater bucket. Put some mardel in qt bucket with him. He'll be there until I don't see any more twitching or scraping then 1 extra week for good measure. Probably another freshwater dip in a few days too. No one else has any issues in tank but will keep prazi-ing it for 1 more 9 day cycle to be safe. I thought for sure I was gonna kill him with that dip. I washed freshwater bucket with scalding hot water and net too.
