Pricing is the same in our Renton location. Emerald Crabs are an opportunistic feeder that will eat many types of algae and scavenge for meaty foods as well. They have been occasionaly known to eat or damage small fish. In aquariums with algae problems these crabs can be extremely helpful. They also eat Bubble algae (Valonia sp.). Quantity discounts available and may be combined with Peppermint Shrimp. If combined we will issue a credit after the purchase is processed.
