I was going to do Qt tank transfer method ? And I wouldn’t be tricking mandarin if I got biota raised ones that eat frozen ? I just don’t want any chance of parasites or ich in my tank so I’m qting everything.
If you buy direct from Biota you do not need to do any of that. I'm partial to isolation when ordering captive bred or raised due to the size. However with Biota and buying direct (key - no middle holding system life online retail or lfs) you remove all that. Plus it is already eating prepared foods so will eat that plus natural.
