Ya I’m figuring this out quickly, my BD are a little bigger and aggressive with food and spook my pearl into flying around the tank like a mad man. Gonna divide them soon if it keeps up.
I’d separate if I was you, Get some weight behind the pearl n him get bigger then try again.
We lost our pearl cos we left it too long, he was eating, and a very aggressive eater, all of a sudden he stopped eating n I watched him starve himself to death, we separated n took him 8 weeks to die, was awful to watch. Not sure if he went into a deep depression or the bullying lowered his immune system and a parasite took hold... we’ll never know...
Good luck n keep us updated.
