Here is another video.
In the middle you can see that I move the camera to the tank beside it, this also has the same ‘infusoria’ development, but here it seem they are smaller and not so dense. In this tank I also discovered two small ornaticauda fry, – and I have not fed these, so I think in a way the fact that there are small live particles in the tank is helping ‘undiscovered’ fry to grow up.
The fry is young harveyi 🙂
