Look at those opea`ula eat all this food. There are hundreds of opea`ula in this tank eating their food. Looks like all those shrimp were hungry after they were shipped from the big island. They must of been hungry after that shipping. These shrimp are eating Spirulina powder. It looks like some kind of liquid but it is actually powder that they are eating. You can't see it in this picture but some shrimp are just resting on rocks that are on the bottom. Some are not even red! Maybe some shrimp did not eat enough food so its color would be bright red. Some shrimp are blurry in the picture because they swimming so fast they must have a lot of energy after eating some of the spirulina that are in their tank. Some are eating algae that formed in the tank and on the rocks!
