With this stocking, I've got issues at the moment with the P. taeniolatus "red empress" who is very aggressive towards both the C. borleyi, and the P. taeniolatus "tangerine tiger".....the tiger is pretty wimpy, but the borleyi without the empress is pretty strong. still deciding who will go in the end.
Just thought I'd give you an idea of my stocklist as you work on yours.
