I will definitely support you. though not a large scale, during my school days, I use to breed Guppy, Platy, Molley, Zebra danio, Rosy Barbs and have supplied to local stores (in Orissa) to keep my hobby alive and to earn little pocket money. After 5 years of successful business, I closed my home aquarium and the breeding tanks for higher education. after 7 years I started tank again( but no breeding tank)
This is how I started my little business:
I used to buy my aquarium stuffs from 2 local stores and I developed that relationship with these stores. I had a big backyard at home. So bought few cement tanks 4' x 1.5' and started with plants ( cabomba & Vallisneria). my local store was very happy to take my stocks because my plants were fresh (no damage by transportation). I think my 1st batch of plants was about Rs 200 (in 1990). That encouraged me to start a fish supply. I used the Plant tanks as breeding tank and started with Molly. It was a quick win and then I added many more. I also used to get small sharks from store grow them in my planted outdoor tanks and then sell them to the same store. After few months my supply chain was streamlined and I had to supply once per week based on pre-orders. I think I had small but successful business. Most important, I enjoyed my little business.
if you are looking for a large scale production, you may have to do a little research on how you are going to market them.
I am currently developing a website (http://aquariumhomecare.com) dedicated to Indian Aquarists. I would be glad to have you as a member. You can use my site to promote your new Business.
