I currently have one Pearl Gourami male in my 45 gallon tank. He is a bit aggressive a feeding time: when all surface food is done, he will go and harass the cories on the bottom. (I will get three more peppered cories as soon as my LFS gets some but I don't know when that will be. I am hoping that with a larger school, the pearl will let them be!) In the meantime, I have been diligently researching the internet for the 'ideal' number of pearl gourami to suppress aggression, but opinions are divided about 50-50: half say keep one pearl, the other half says more (then, some say get 1 male - 2 female ration, other say get a pair). I really like my male, he has nice colours and is the king of the tank. Can anyone share their experience with one or many pearl gouramis?
