Thank you. So the same rule applies in case of only one piece of demasoni in tank too with peacocks and labs and dolphins?I've been keeping demasoni for 14 years and peacocks almost as long. I would not mix, if the demasoni don't end up stressing the peacocks causing illness/injury/death then I would expect the peacocks would at least not show their best colors. Also I like peacocks in a harem or a single male with no other peacocks that look like him in the tank.
