how betta fry go from egg to fully grown bettas |
| This page would not have been possible without the wonderful help of Wayne Schmidt, who came up with this wonderful idea, took all the photos and wrote the data. He was kind enough to allow me to publish it on the bettatalk.com website. Many thanks to you Wayne ! | |

I thought it might be interesting to post a photo chronicle of a betta's growth from egg to adulthood. Every week I'll add a picture set to display at full size for a monitor setting of 72 ppi. This way visitors who haven't raised bettas can view the growth process. As a reference, the line below is one inch long. ________ If it looks one inch long on your monitor, you'll be seeing the fish at their actual size. Be warned, young fry are so small that they will appear as little more than specks. . Betta egg: 0.03 inches in diameter
After eleven weeks of growth, the amount of week-to-week change is too little to be interesting. From then to seven months of age the betta's body shape stays the same with a very slow increase in size. The fins grow at a glacial rate, eventually developing their full length at seven months.
