The Randalli Pistol Shrimp, Alpheus randalli., also known as Snapping Shrimp, or Symbiosis Shrimp are marine invertebrates that have one extra large claw it uses to snap at prey to stun them. They are also known for forming symbiotic relationships with gobies - this can be an incredibly fun and rewarding relationship to watch in a home aquarium. The Gobies warn the Randalli Pistol Shrimp of predators and the Pistol Shrimp will share its food with the Gobies. It is reef safe and comes in many different colors and variations. It is best kept in tanks with ample amounts of rockwork, a sandy substrate, and and will scavenger for food as well as accept frozen aquarium foods. 

Tiny little shrimp but he was pretty. I bought him for my watchman. I haven't seen either since putting them in the tank. I haven't not seen any bodies so I suppose they are under a rock somewhere

Very Small, but very healthy. I would not recommend purchasing if you have large fish that pick at their tank mates. I purchased to pair with my Yellow Watchman Goby (about 2 times the size of the shrimp), it took approximately a week for them to find one another but they are inseparable now. Very interesting relationship to watch in your home aquarium.

This pistol shrimp arrived in great health and is flourishing in my tank. Would recommend.
