My Blue Gourami was the first fish I put in my 55 gallon after it finished cycling. I have been slowly introducing new fish over the last few months, but the Gourami has always been my favorite fish. Very peaceful, he has always kept to himself (and has gotten fat). Well today I decided to buy a Opaline and Dwarf Gourami. Blue went nuts, all he has done is chase them since I put them in there. He will chase one, stop to take a breath at the surface and then chase the other one. Round and round the tank - the other fish have hidden ever since it began. Help!! Will this calm down after they have been in together for a while? Any advise?
