Sorry for these very newbish questions but I'm wondering if I could breed and sell fish to the LFS for store credit. I am thinking about starting easy with guppys maybe? This is my first time trying to breed. I'm not in it so much for the store credit, but for the learning experience. I do how ever want to make some money in store credit that would be nice. How much money can be expected to make from selling guppies to a store? $.30 each, $1.00 each? I have no Idea the price range, I know it varies different fish but I need an Idea. My fish stores are Petco, Petsmart, and House of Tropicals. I prefer House of Tropicals any day.
