I disagree with those expressing preference to do it with the lights out.
Just imagine yourself thrown in a dark room full of enemies. Where are you
going to hide? can't see!
There will always be fights even in compatible fish.

4. When? I prefer to add the fish half an hour to an hour before lights
out. At least they get the chance to find a hiding spot before lights-out.
In the dark, residents can travel around the tank easily. Again, there will
always be competition.

Yea I often do it that way, put the fish in, watch it long
enough to make sure it has time to get some familiarity
with it's environment (around 10 minutes), and then turn
off the light.
