Relevant Information:

There are a few similar looking species such as L096, L160 and L375. It is not known yet if these are distict species or just geographical variants of P. spinosus. Aquarium care: Would need a large tank as they grow big and are territorial. Diet: As with all of this genera they are carnivores and would need to be fed on frozen foods such as Artemia, mosquito larvae, mysis and shrimp. They can also be fed pellet and tablet foods.
