Breeding Zebra Danios

I am currently breeding Zebra Danios and I have a couple of questions. I found a really good site but then it turned out that modelling my fry's life cycle is not even close to his.
My first two fry are 24 and 22 days old, their eyes have become much bigger, they are wider, about 2mm longer than when they first came up and their internal organs are bigger and pinker. I fed them infusoria (3 drops 3 or 4 times daily) until yesterday when I started feeding them freshly ground food. They are living in a 0.866 gallon tupper ware container at the moment and I'm wondering if this is a normal rate of growth or are they growing slower than this person's model because they were in a 10 gallon tank and they were fed grindalworms, microworms and newly hatched brine shrimp as well? According to that guy's model my fish are around the "7 day old" mark - 5mm with a neon stripe. Has anyone had any experience with breeding zebra danios than can help me with that?
Secondly, I have 165+ fry in a 10 gallon tank which is about 3/4 filled with 2 inches of marbles on the bottom and a sponge filter. I started feeding them infusoria yesterday with meals of 6-8 drops 3 or 4 times a day. I am not sure if I am feeding them enough, is there any way to know?? I bought a brine shrimp hatchery and I'm going to set it up on Wednesday night to have it ready for Thursday morning feeding. Has anyone had any experience with those?? The model I was following says that if you do everything properly than at day 28 the fry should be moved to a growout tank of ~50 gallons. My early 20 day old fish are certainly not ready for the bigger tank because their mates would make lunch of them. I only have a 23 gallon tank that is currently occupied by 10 adult fish available and I may be getting another 10, a 5, and if no goldfish survive the summer than another 5. So is it the size of the tank that matters or the space? Adult fish only grow to ~1.5 inches.
Any advice would be appreciated!

I used the brine shrimp hatchery and it worked because for 24 hours I had more than enough food but a lot of the eggs never hatched, which I thought was quite weird? My fry look a lot bigger after being fed brine shrimp for two days. I moved my two 30-day-old fry to the 10 gallon tank downstairs, they are much larger than I thought. Probably ~7mm and their tail fins are developing really well. They are much whiter than the other fry and they have these startlingly beautiful turquoise eyes. My LFS agreed to purchase my fish at the price of .25/pair. Better than I thought! I thought they'd be like 5 cents a fish? Anyway, so that's like 20$ store credit. I guess if you breed them often enough eventually you'd break even.
For these fry I bought: infusoria @ 6.99$, brine shrimp hatchery @ 20$, dry fry food @ 2.99$, sponge filter @ 10$.

The sponge filter I can use again and again, I didn't even put a dent into the dry fry food, the brine shrimp hatchery can be used again but refills are 8$/3 packs of eggs. The infusoria is probably 75% done so I'd have to buy more..

8+7$ =15$ so I could technically start making 5$ each time I sell a batch! Hurray! lol.. 2-3 months of work for a 5$ profit. Ah well, it's really fun to watch them start off as lil eggs inside their mum and end up like my month old fry who actually look like mini-fish. I will probably keep the two oldest fry and sell the others in 2 months or so to Big Al's. They told me to just call a week ahead and they'll prepare some tanks but how the hell am I supposed to bring in 165 1.5 inch fish? They told me to just bring them in a bucket but the largest bucket I have is 2 gallons... eeek!! Luckily it's only a 15 minute drive but it will be QUITE interesting to watch me do this... lol..... Does anyone have any experience doing this??
