So my plan is to let the new 5G run on its own for a few weeks and let the CPD's get used to their new home. I plan on feeding the CPDs a mix of crushed flakes and frozen food. Once the new tanks is stable I'm thinking of taking 2 of the bigger CPD's and letting them do the mating dance in the planted 5G for a day or two then moving them back to the big tank. The 5g will become the new home for the frys until they are big enough to move into the 12G with the others. Has anyone on the forum tried breeding CPD's before? Is there anything special to do or just let nature take its course..
