First of all, hi and welcome to AA!!!. She definitely pregnant alright and I would say she is very close to giving birth, no more that a week away. She seem to squaring off nicely. She will be pregnant for 4wks, every 4wks. She only needs to say hello to a male and she will be pregnant...haha. They can also store sperm for a few months usually around 3, so she can be pregnant even with no male around....
Don't worry, you'll have plenty of fry in no time!!!
Great stuff. They seem a decent size and active, which is always a good sign. What size tank are they in and is the mother still in there with them??
No, your doing everything perfect. First bites is a great food, I use it with my fry. Just keep an eye on the water quality as they grow. Ideally you should have a bigger tank for them but after about 4-6wks, they should be big enough for you main tank. As long as they are bigger than your biggest fishes mouth, they will be fine. As they are young, they will be sensitive to poor water but you are definitely on the right track. You could look into a food called Repashy gel food. It comes in a community and meat pie variety versions. I use both, in rotation. I use this after about 2wks. I mix some of the first bite power into it. The fry go mad for it...
