Tiger Shrimp on nite dive

This Tiger Shrimp was found at Coral Garden in front of Paradise Hotel Tulamben, Bali during the night dive.

It was one small and one big. But this picture is the big one. They was hiding behind the Hydroid that grow around the the rocks.
Tulamben is actually rich with macro and other small creature. The topography are mostly black sandy bottom but at certain area there are some coral.
