Novice Fish Keeper

Question
I am wanting to buy a fish and i have a couple of questions:
1. I want a freshwater fish that does breed but not at a fast rate. whats a good fish for that?

2.I have a 100 gallon tank, are all fish suitable for that?

3. I want to keep it under 10 dollars. What are the prices for the fish above?

Answer
Hi,
There are freshwater fish that can grow over 20 feet long, so not all a suitable for any aquarium. A 100 gallon is a VERY good tank to start with.

Fish that fit you're  lists 1 and 2:
Angelfish,
Halfbeaks,
Nearly all cichlids,
and there are literally thousands of others that will fit, but breed ether quickly or very rarely.

Fish for #3:
If you really want to enjoy the tank, you'll have to spend way more than $10.

Have fun!
