What is the grass in the background? I believe the Fauna is the Dwarf Sea Horse (DSH) Hippocampus zosterae. The Sea Grass Might be the so called Turtle Grass (Thalassia restudinium) but I am not sure. The reason I would like to lnow is that I would want to keep both in my Aquarium. But if it is in fact Turtle Grass I would have to have a 10 inch sand bed. That is something I don?t want to do.
