I've had the larger for ~6 months and the smaller ~4 months. Larger of the two is transitioning to blue. Weaning the smaller onto frozen was a major pita but they are now both eating a rotation of salmon, halibut, flounder, cod, amberjack, mahi, and tuna. They will occasionally eat octopus and squid but not as aggressively as the fish offerings. Won't touch thawed silversides.
