I am interested in breeding some red cherry shrimp and selling them, obviously I won't get a lot of profit, but I'm hoping to be able to get some money which I will probably put to getting more fish tanks or supplies for my fish. I currently have a 2.5 gallon tank, but can upgrade them as I grow, so I am wonderin ghow hard is it to take care of them, breed them, and how many can fit in a 2.5g tank. I am hoping if the business grows some, I can also save up a little bit of money for getting a 5g tank or larger to help increase the business. Hopefully this can grow to a low stable income so I can upgrade and get more fish tanks (currently working on a 55g which is my main priority. Thanks ahead.
