They would rarely ask for food when I would approach the tank. Now every time I come up they get excited and think it's feeding time It's good to starve Mbuna for one day of the week to help their digestive system catch…

I feed them randomly really. what about you ?

Juvenile sharks have to do the same? They have to keep swimming from birth? Yes, they are hatched in the mothers womb and are active when they leave.

Does this also mean they don't sleep? If I remember correctly most of their brain sleeps, just a part stays awake. Just like how horses can sleep standing up.

Shark constantly have to keep swimming to keep water passing over their gills.sharks need many things, including a certain shaped tank to allow for this glide pattern. For human its hard to keep this all things up
