Hi all! Quick question. I was given a giant gourami at about 4-5 inches. It was as placid and chilled out as you can get, not a problem at all to keep. Once it hit the 9-10 inch mark it started acting very aggressive and bashing other fish up, over night it demolished my 12 inch indian shovel nose and it attacked my oscars. Now someone told me this a almost a phase they grow through. I'm wondering is it a phase, or do i just have a violent fish?
