Heh... they eat newborn pinkys and lg fuzzies, respectfully, every five days because they are TINY! My Anery is @65g and my HypoBlood is only @6g. That's my whole problem! If they were adults, I wouldn't need to wait 2-3 years to start breeding my corns...hence the question of how old/large males can be to still breed effectively. I want my boys to still be able to work effectively in that long a time.
