Thanx for the nice comments everyone!
Reefbaby- The male cardinal holds the eggs in his mouth for about 20-28 days. During this time he does not eat. He is not doing anything "special" during this time with the eggs, just protecting them from being eaten.
He does tend to consume a few eggs during incubation. So really the male is not needed after the fertilization is done. By forcing him to spit the eggs out early he is given the opportunity to continue eating and remains heathy. It also allows me to get a higher yield per nest and allows the next mating cycle to occur in a shorter time.
TRS- Feeding them is not difficult. I use decapsulated (hatching) baby brine. No shells, no muss, no fuss. And just what is wrong with Boston?
I wanted something just to cover the loud background noise of all the pumps and water gurgle at the shop.
Glad you are all enjoying the video. More to come.
