Very well done video by EliteBetta.
I don't know if I would go through all that trouble to make a pureed cow heart mixture for the newborn betta fry.
Anyone who wants to try to make that enriched fry food.......
Be aware all the ingredients & the supplements should cost you at least $35-$50.
I thought this video was made for the people who are raising FRY & juvies.
I'm a bit surprised EliteB fed the heart mixture to his adult betta. It seemed like that betta had enough belly fat to last a whole month without food.
Also the trimmings of connective tissue & fats that EliteB removed from the heart, can be cut up into medium sized (Parmentier) 1/2" chunks & frozen. You can use the leftover heart trimmings to treat your "ACTIVE" dog over the course of 2 weeks.
While it is considered WASTE material, it should still be more nutritious & healthier than feeding your pooch doggie treats filled with grains & mechanically separated proteins, full of all sort of preservatives and other unlisted chemicals.
If you want to feed your betta a NATURAL diet, then maybe you shouldn't offer them Omega 1 products since they contains SALMON & ROCKFISH instead of the bugs/worms that bettas eat in their natural mud filled rice puddles.
Here's what a rockfish looks like.
