No, they don't have eyes or they're just blind.
A planaria obtains food by using eyespots and special "smelling" cells to locate food. Then the planaria inserts a feeding tube and releases digestive chemicals. Then the planaria sucks up the half digested bits of food. Lovely, isn't it!
Both would be appropriate, as long as the planaria can reach that food source.
No, planaria do not do photosynthesis. They are free-living flatworms that are primarily carnivorous, feeding on small organisms in their environment. They rely on external sources of food for their energy needs.
The planaria class is Turbellaria
Corys will eat planeria corys need small amounts of food

sp refers to a planaria where the actual species is undetermined...or sometimes because several species of planaria have similar appearance or behavior and have been used in a study.
Usually a planaria regeneration experiment involves cutting the planaria into different parts. The head can be separated from the tail or the planaria can be cut lengthwise, etc. After cutting the planaria, it will be observed for few days noting how the organism regenerate its lost body parts.

The auricles of a planaria serve primarily as sensory structures that help the organism detect chemicals and changes in its environment. These ear-like projections are equipped with chemoreceptors, allowing planaria to sense food sources and potential predators. Additionally, they assist in spatial orientation and can contribute to the overall sensory perception of the flatworm.
Planaria ingest food through a flexible tube-like pharynx that it can stick out from the middle of it's ventral side. The mouth is located at the end of this tube. The planaria sucks food in through this tube.
Planaria prefer dark environments
NaCl, also known as salt, can affect planaria by disrupting their osmoregulation. Planaria have a delicate balance of salt concentrations in their cells to maintain proper water and ion balance. Excess salt can cause dehydration, while insufficient salt can lead to swelling and bursting of cells in planaria.
