At this early age and small size, I feed mine constantly...when he looks like he is on the hunt, and will eat, I will feed him.
I change what I give him everytime he eats, that way he won't get spoiled on one or two certian things. I been gut loading Hikari pellets in everything to make sure he is getting a balanced diet. He also likes to have the pellets plain...
There will be a day in the future that he'll only get fed every 2-3 days...A big ol'prawn or 2-3 Crawlers at once...but for now ...ALL HE CAN!!
