What size is your tank? Also what size is your female motoro? I am hoping to breed my male flower with a motoro. Trouble is my male flower has overtaken my female motoro. He has gone from 11" across to 17" across(30" long) in one year and is only just maturing now. Mine is incredibly active and will eat 500g of prawn or mussel in under 3 minutes.Also he is very aggressive. He has almost outgrown my 8 x 3 x 2 in 10 months. I now think tigers and flowers really are only suitable for ponds or wide tanks.
He has started biting my female and am starting to worry more for him than her as she already killed one immature agressive male motoro by stabbing him in the stomach. Good luck in your plan.
