Sorry a bit late but just to add smthing.

The grey ones, malay called it 'Udang Lipan'. Direct translation would be 'centipede shrimp' but more like a mantis than a centipede. This colorful ones should be corals inhabitant. The grey ones i love eating them steamed. Slruppp.. delicioussss.. and cheap too... the grey ones...

It's good that you have this one, although it eats other fish. try isolate it. pretty thing though..
