Their cultures tend to crash when the water temperatures go outside of a certain range and the water quality declines too far. They can be fun to culture on their own as a school project as well! In the photo above, the yellow is the digestive tract. The black is a forming egg. The second photo is the top view. The antennae they use to swim with can be seen. Tips 1 to 3: 1.
