many sharks are at least moderately social, and if a specific species of shark has the ability to breathe without actually swimming and tends to have a lot of sharks in a fairly small area, well.
they are just going to Pile. and there is simply nothing you can do about it.
also, fun fact! whitetip reef sharks in particular are SO damn cuddly with each other that they’ll actively seek out a buddy or ten when they get sleepy!
it’s pretty much slumber party or nothing for these guys. you won’t find a whitetip sleeping alone except in the most dire and tragic of shark circumstances.
