I have a 150g tank with 26 haps and peacocks male. About a couple of months ago, my lwanda would stay at the corner of the tank (seems to be hanging out higher and higher in the corner) in a slight diaganol direction upwards and just hang out there all day. If i get close enough, itll then swim around with the rest of the fish. But as soon as I leave, it goes back there to hang out. During evening, it would then swim with the rest of the fish. He eats and poops normally. Water is good, nitrates low, no ammonia. A little worried about him but everything else seems normal. Any ideas?

He is being harassed so make a change to manage aggression so he does not get sick and infect the tank.

Could he be a female? Do you have more than one Lwanda?

It's expected to have to rehome males with an all-male tank so the easiest thing to do is rehome him.

Agreed. The #1 of a fish being bullied or harassed is hanging up in a corner near like a filter or heater. Possibly even a female (do you know for sure if it's a Male?)
