Lots of good advice and so on given, I have not read through everything but will give my thoughts as someone who mostly kept fish in his highschool years. Now at Uni I have scaled down significantly.
Making money outright from fish is difficult. You either have to breed something that is high in demand and high in value, which usually means difficult breeders or a lot of investment. Or you have to breed lots of cheap animals to break even. It's an economy of scale. I had small catfish worth $8 each but I did not have many and after some mistakes never got fry far in development before I had to sell them for uni.
Also, you have to spend money to make money. 4 shrimp are going to take forever to lift off, 40 shrimp and you'll be overrun in no time. I found having lots of extra plants is always handy for trading and so on. To create any setup worth putting the effort into to make money your capital investment will be fairly significant and will take a lot of time to manage. If it were easy anyone would do it. I make significantly more now working part time at Uni than I ever would have working with fish.
Shrimp are fairly easy and are always in demand so I would definitely try stick with that. Sponge filters are preferable as they don't suck in shrimp and give lots of grazing area. Good luck
