Planaria worms will occur naturally if you have a well balanced/planted tank and continued occupancy by larger species of fish (like Cichlids) that will not eat them because they are too small.
Both would be appropriate, as long as the planaria can reach that food source.
With knowlege and all the right equipment a small tank can easily be set up in an hour.
The planaria class is Turbellaria
planeriacomes under kingdom animalea
They are "Planaria worms". They are harmless but they will become more numerous and eventually you will have to do a complete strip down and clean out of the tank in the not too distant future.
no because you just now set it up and it needs to cycle
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.

Planaria prefer dark environments
Provided the tank is clean and has been set up correctly there should be no problems.
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.
A leaflet should have come with your tank about how to set it up and the equipment you will need but here is how i set up mine....... put ur tank away from direct sunlight or sound systems, your tank needs to be near plug sockets. 1.Thouroughly clean the gravel, ornaments and sindes of your tank with warm water, (DO NOT USE SOAP) 2.set up your filter and air stone in the tank. 3. dose water with nitrate killing stuff that you can usually buy in all pet shops 4. add the water carefully as not to move the gravel at the bottom 5.leave your tank for about a week to settle before adding any fish 6. buy one or two little fish to see if they survive, if they are ok you can start to any other fish. HOPE THIS HELPED (these were the intructions that came with my tank, i did not make this up)
