It really all depends on if you like the taste of them. if you dislike eating them, then might as well look at pretty golds or kois.
tilapia I've had is always good. love it with lemon and black pepper
Won't the newly born tilapia fry spend most of their time in moms mouth and she feeds them somehow. If baby guppies would eat the powder I guess they will also. My 1 inch baby ate the small pellets from day one and also munches on crushed food when I use that. The pellets I got this time are very small, less then the diameter of a toothpick. Yet they float and even the smallest of babies picks one out and holds it in its mouth till it is soft and then gulped down. That takes about 3 minutes. With so many minnows I like the fact that everyone gets fed. They all hit the pellets on the surface and take it down to crew on. The gold fish take big mouthfuls. I am hoping my new larger jugs come in tomorrow as promised.
I am hoping to get something that lays eggs so I will have many of something. 30,000 snakehead babies would be cool too. They are really good to eat so I am told and read.

If you mean that when the eggs hatch they carry a bit of it around with them. Ok, lots of fish can do that and it would give them the extra time needed for eating and growing. I would guess that moms mouth will be a good chewed up feeding ground for them. They suck them in right from birth and keep them there for a log time.
No, the yolk-sac is a little different than a bit of the egg from which they hatched being carried around:
Even human embryos go through a stage where they've got a yolk-sac:
Eventually it gets incorporated into a primitive gut.
Several sites seem to confirm that Tilapia fry leave the mouth after yolk-sac absorption after which they are no longer called yolk-sac fry and are called swim-up fry. While they may return to the mouth for a few days for protection, they for the most part are on their own after leaving the mouth.

Tilapia larvae can accept artificial feeds right after yolk sac absorption. The first feeds must be high in protein and energy to match the high growth rate potential of the larvae.
