@Fish Fan has you covered but It took so long to type my reply below because I type so slow there's no way I'm deleting itExcuse my ignorance, but what’s the issue with 3 clowns? Should I only keep 2. They were included in the tank tho. I have notice one at the corners of the tank often, but I don’t see aggression …
All clowns are born male. As they mature one transitions to female. Usually it is the most dominant fish that changes but often the other doesn't agree and they fight to see who wins and gets to become female. Often its a quick process but it can result in death if one does not submit or the female chooses not to except the other as her mate.
Normally it doesn't work with 3 because after one transitions to female and chooses a mate there is an odd man out and the pair generally does not tolerate an second male. It can work in large groups called a harem but typically does not work with a trio.

I'm much the same way, I don't type correctly, I use like three fingers, but I'm mostly on a PC or MacBook and less on my phone, so I'm able to reply quickly most times.
