I am upgrading from a 46 gal
to a 125 gallon 60 X 24 X 20. I have a pair of percula clowns. They are mated. I REALLY want a pair of Half Onyx Clowns and I know I would be asking for trouble adding them to my existing tank, but.....would I be able to have them coexist in the new tank if I added both pairs at the same time. hence, no territories set yet.
I don't want to harm or stress my existing pair unnecessarily. What would work - if the new clowns were smaller/same size, introduced first, etc. Or, am I asking for trouble.
Thanks for the input.
