Fish Fanatic
If you want to make money breeding fish, you need to breed something unique. Run of the mill fish just will not be profitable.
For example, there is a guy who is breeding INSANELY rare clownfish in Australia. He is the only one in the world. He stands to earn a lot. But he also put a ton of effort and money into it. There is a thread floating around another forum regarding his "adventures"
Breeding BN Plec's is something i've put some thought into. They sell them for a decent price at the LFS($25), and from what I hear, they're very easy to breed.
Mine sells them for $6 in the US. Unless they are full adults, they're overcharging. Although, I don't know what your local fish "economy" is like in Nova Scotia.
They sell the adults for $25, the baby's for $20. I think a big reason for that is the fact that they have trouble getting them in. There's 3 major Pet Store's around here with fish. One of them I don't think has ever carried BN's, and the other 2 get them in whenever they can, but they usually go very quickly.
