[i have crabs]

im not selling mine but if your looking for them to breed and sell i cant see it being a worth will venture. ive raised 2 batches over the last year and a bit and the amount of time,food and tank space you would need would make thing real hard to profit from.as far as just doing it for yourself, its lots of fun in a sick hard work aquarist kind of way but its not really that hard you just need a mature pair (over 2 years old) and feed the heck out of them.
