Good point I'm most likely gona stock all the fishSomething that wasn’t mentioned but might be something to consider is...are you being over cautious and building up too big of a BB colony?
If you have too much BB and you only transfer one fish into the new tank and say this new fish doesn’t produce enough waste for the BB to survive will the die back of the BB cause problems for your tank? (I’m not an expert of the sorts but wanted to put that out there in case someone else might know)

You bring up a good point
