Alright so I have 2 Pearl Gouramis and another gourmi (I forget the name, looks just let the pearls, but orange) in a 20 gallon (long). The orange fish is really chasing the 2 pearls. He isn't harming them, but he chasing them, and they spend most of the day hiding, I also have 3 paradise fish in the tank, but they are getting along fine with everyone. Do I need to get rid of the pearls, or couldI try something else like putting more plants in the equirium or....
