Oh, and the best way I have found to train lions onto frozen foods, works with ANY lion. Float a bag in the tank with the feeder fish in it, the lion will eventually swim over to investigate, then let him watch it for a while, then scoop out the fish and drop it near the lion in the tank. Pretty soon the lion is snapping it up before it hits the water, and then you start dropping frozen foods in, then pretty soon you can stop floating a bag with a feeder in it and just drop food into the water and it will be eaten readily. Worked for me countless times, although to be honest, its probably a longer process than most people use, but i doubt it has less than 100% success rate and an extra week or two of fresh water fish cant really hurt in the long run Id think.
