I’ve always dreamed of owning a Peacock Mantis Shrimp (Odontodactylus scyllarus). They’ve always seemed so unique to me, so I set up a dedicated aquarium just for one.
This is my very first time owning any aquatic animal, so I was both nervous and excited. I set up the tank, cycled it properly, and when everything was ready, I started calling around to find one. Eventually, I found a local fish store that told me they could get a Peacock Mantis Shrimp for me. I specifically told them that’s exactly what I wanted.
A few days later, they said it had arrived. When I went to pick it up, it was much smaller than I expected. Since I’m new to the hobby (and they knew that), I assumed it was just a juvenile and that’s why it lacked the bright colors. I even asked the owner in person: “This is a peacock, correct?” He doubled down with, “Yes, this is a peacock mantis shrimp.” He even told me, “In about a month, the colors will start showing.”
So I purchased it, brought it home, and acclimated it to the tank. Later, while observing it more closely, I noticed the distinctive blue meral spots with sharp white rings on its raptorial appendages. I did some research and realized it’s actually a Gonodactylus smithii, not a Peacock.
My questions:
1. What should I do in this situation?
2. What are the main differences between G. smithii and O. scyllarus?
3. Do you think the LFS owner knowingly misidentified it, or was this an honest mistake?
