The blue one is of Omlette, he was my model. It's actually so realistic when you see it that when I showed it to my sister she screamed because she thought I killed Omlette. The second one is a make-believe marble white, black, red, and blue veiltail betta that I just made up when I was bored. Both fish are made from polymer clay (Fimo and SculpeyI, II, and III) and baked in a toaster oven at 200 degrees set on medium. The marble fish is a little lumpy though because I made him too thin and he burned and got all lumpy. Thankfully I made him out of scrap clay and just painted over him! I've been "working" with clay for around 5 years. When I was 8 my mom found a giant bag of clay at a yard sale and bought it for me. Even earlier I played with reusable kid's clay. Polymer clay isn't very expensive, but Fimo is very hard to work with because it is so hard.
