Haha, I didn't either until I started to get REALLY into breeding betta. Just print out a few good pictures of betta, like and practice writing the anatomy they have down.
I agree with dq! Your spawn will come out great!
I have a mom and grandmother who LOVE to can food, because they both have huge gardens, and I am going to use some of their extra jars. But, not the little 6 oz ones, the biggest ones the make are about a gallon I think. You can also make a "holding pen" out of plastic canvas, I made one, and it took about a week to make, but it looks pretty good. Should suffice I guess.
