I have three LFS Within 30 minutes of where I live. also have twice that many BIG BOX pet stores.
I raise guppies and bn plecos "for profit" This term cracks me up! All three of the LFS said when I started out, they will buy from me. One shop stinks and I will sell them nada! (worst thing in my life is walking into a pet store and it smells like a dirty cage. I know animals have odors,,, big difference!)
I told one friend, if all goes well, in a year I will be selling enough of the stock I raise to the LFS to pay for the extra electricity and water that is used each month! LOL "Breeding for Profit (insert joke here)"! I would rather deal with other hobbyist to get my best fish that I can not retain as breeders
Now, I do understand that thing I bought that pair or trio for $25... they had 2 or 3 drops of (guppy) fry and you end up raising 100 babies from that ,,,, You cull some for defects, some die, you keep the best for breeding, and end up with 50-70 fish you sell to LFS for $1, most often NOT at the same time, but over months, the same way the guppies were born.
So $25 fish get you 60 (?) in sales to LFS,,,, Great,,, Not really breeding for profit, but getting paid back a bit of the investment you have put into them, the hobby, Great.. parents paid for themselves WONDERFUL! You meet some GREAT People working in a thing like this, some will be your friends for life. some you run into them, pointing at each other saying "I know you..... ?" Again, wonderful!!
But let me point out another aspect. I did a similar thing years past, built a stable of breeders in several species, upgrading from what I could get in pet shops and from friends, other hobbyists. I had whole room built to spec and equipped for my hobby. In or years, I had a reputation, was working with several stores (even a small local chain) around the state. I had breeders from several other states seeking my stock and breedings , , , I was working almost as much on my hobby as I was at my full time job. Building up to 5th year, fr every $ i invest, i made 3... sounds great and was truly breeding for profit. But unless you have a large family and/or group of friends to trust in the care of your stock AND can rely on their dedication, well.... you hit the wall and just DO NOT want to NOT do it but start thinking about NOT taking it on at the level any more. And the market, loss of Ma&Paw pet shop places, I thought for about a year, and that old story, some one comes into your life and she changes it (no! she did NOT tell me I had to get rid of that stuff), but I made the jump. Decided to get out, passed a great bunch of lines of one species to a family that wanted to take them forward. (they got SUCH a deal, and though a state away, filled my niche for part of my state) Same with a few of my other species, but as scattered to the wind as it was or seemed.... I could now DO things like LEAVE home, take the dogs and not worry for a long weekend!!! Turned that room into a plant room and eventually a home theater decide to go somewhere, call the dog sitter and be gone for the night!!
