20 years or so ago i bred VTs. i kept the ones i liked and gave the rest away. we used to have a free newspaper that i was able to post a free ad. i gave them away no problem. i did not have huge spawns though. maybe less then a hundred.
i would guess that an ad in craigslist might have the same effect today but im only guessing. you may or may not be stuck with alot of bettas.
im not saying that everyone should depend on being able to give away their fish on craigslist.
i am planning to breed some HMs in the future and have already talked to a lps. whether i start with high or lower quality fish i want to be able to sell them. he said that he would buy any fish i had but only at 65 cents each. this is because he can sell 150 VTs a month and make $1-2 each while he could only sell 2-3 HMs a month. he doesnt want to carry higher quality fish.
if later i do end up with high quality fish. then i will sell them for more whether it be to stores or online. but at least for now, i know i can sell them for 65 cents to a local pet store.
The fish i do plan to breed in hawaii, come from either a lps or local breeders. i will try to improve on what is available here but i might be biting off more then i can chew. ill prob start a log and people will be able to see how much work it is and if i succeed.
