Will hopefully be moving 11 fish (6 tetras, 5 small Bolivian rams) from their 20 gal isolation into my 55 tomorrow. Seems like it would be a huge pain to bag all of these fish so I was hoping that I could put them and some of their old tank water in a 5 gal bucket, then gradually add some from the 55. My concern is that this may not be enough space for 11 fish. They'll only be in there an hour, 80 min at most, so I'd think they'd be fine but anybody else have thoughts?
