Yes this is in the right place as far as I can tell.
On the question of other fish, I started of with platys as they are quite easy to breed and it gives you the experience of raising fry, I think a couple of platy spawns, or even guppy spawns would be a good experience before trying to breed bettas as they are considerably harder to breed, the best thing you can do it read read and read some more!You can never prepare yourself enough, also you need to think about food cultures and research those for feeding any fry, I do daily 25% water changes for all my fry.You need to know this is a LOT of work, from one single spawn bettas can produce up to 600 fry (in my experience, someone else may have had more!) you need a massive grow out tank, seperation jars for the males. I'm not trying to put you off I just think people need to know what they're letting themselves in for! I have to say though there is nothing quite like raising a baby and seeing it grow up into adulthood!Good luck, I hope I helped!
