Sounds like you put his proverbial nose out of joint! Keep your eyes on them tho, I have 3-spots that make smaller fish go missing without warning. Wilst they will tolerate some others they kill outright. I've had 4 danios (one full grown) and a number of otos go awol in joining their tank. But mine do breed and that does make the male more aggressive.

That is typical behaviour for most gouramies. They are territorial (males particularly) so will consider new additions to be 'intruders' and chase them around. Thankfully, pearls are one of the more tolerant species and quickly calm down. I wouldn't expect any more trouble now.
