do you have time to watch the pair spawning and recording the actions all day for two-3 days?
do you have enough space to raise up to 1000 fry?
do you have time to feed each fry 3 times a day?
do you have enough water and conditioner and medicine and time to do weekly water changes in each jar?
PLEASE think about this before you start, or you will be very dissapointed when all of your fry and/or the parents die. it's a VERY long involved process adn shouldn't be taken lightly. If you are having trouble raising goldfish, maybe betta breeding isn't the right thing for you at this moment. i'm not saying don't do it, but just be totally prepared for it. remember, learn learn learn and THEN try!!
