I need some opinions as to what color of sand is more ideal for african cichlids. I havent decided yet if Ill be keeping Malawi or Tanganyikans. Im reading conflicting ideas on this. On one hand Ive read that white sand is best because it more closely resembles the substrate in the rift lakes. On the other hand, Ive read that darker substrate is better because the fish's color will be more pronounced. And also because the fish will feel less stress due to less reflecting of light off of the substrate. Im really confused as to what to go with. Thanks!
