Presently I have two established tanks. Tank#1 : 75gallon stocked with White Tops and Yellow labs. Tank#2: 55gallon stocked with Saulosi and White Labs. I want to divide up these by adding a new 55 gallon tank I now have. Are the labs the only species that I shouldn't mix of these four? I know I need to move some Saulosi and am thinking of Saulosi,White Tops and either Yellow or White Labs in the new 55. Sound ok?
