I recently bought a powder blue dwarf gouramI and a honey blood red gourami. I got the blue one first and he was being bullied by my rosey barb. that soon stopped but then the gouramI staed in the back corner, hardly ever commin out. he seemed rele shy and nice. then I added the red one and the blue one chased him and nipped at him every time he tried to go to the back. now they stay away from eachother in seprate corners in the back. will they ever get along, and will they ever come out of the back more?
