Also if a fish seems slow once you put it back in the water, you can kinda run it back and forth a couple times to get water through its gills and that will help em.
Small panfish and stuff, try and get them back in the water within a couple min. Big carp and catfish we get around here can last hours out of the water, it's fucked up.
