I am not doing marine fish yet. Because they 1. cost more 2. harder to sell >< A specialty fish store... wouldn't that be more expensive anyways?
And here, the main interests: space friendly fish (bettas), small animals for kids (hamsters), and mydogissospecialimustgethimacoat dog fashion :p So even if I do start small, it'll have what sells the best. It makes it better if I can do some of the stuff myself too :)
Plus, a specialty fish store... then the electricity goes up, water bill, buying the fish, buying tanks to use and sell....
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
