Mantis shrimp, also known as stomatopods, are a group of marine crustaceans that are closely related to shrimp and lobsters. They are called “mantis” shrimp because their second pair of appendages resembles the large, raptorial front legs of the praying mantis. There are over 500 species of mantis shrimp, found in shallow tropical and subtropical waters around the world.
Mantis shrimp are highly prized for their beautiful colors and unique behaviors. They have become quite popular in the marine aquarium hobby, but their expense depends on a few key factors:
Species
There is a wide range of mantis shrimp species and some are far more rare and desirable than others. For example, the peacock mantis (Odontodactylus scyllarus) is one of the most sought-after species. Their vibrant colors and striking patterns make them a favorite among aquarists. A single peacock mantis can cost $150 or more. On the other hand, more common species like the brownbanded mantis (Lysiosquillina maculata) usually sell for $20-40 each. The rarer and more colorful the species, the higher the price.
Size
Larger, mature mantis shrimp command a higher price than smaller juveniles. A full grown 6-8 inch mantis can sell for over $100, while tiny 1-2 inch juveniles go for $20 or less. The extra cost is worthwhile because larger individuals are healthier, stronger, and have more impressive claws and coloration. Buying a tiny mantis shrimp means waiting months for it to grow out.
Color Morphs
Some mantis shrimp species have color morphs – variations in coloration. For example, the zebra mantis shrimp (Lysiosquillina maculata) has a rare and expensive “harlequin” morph with intricate white spotting over its body. These rare color types can cost 2-3 times as much as the normal morph. Unique color patterns are highly desirable to collectors and breeders.
Captive Bred vs Wild Caught
In general, captive bred mantis shrimp are more expensive than wild caught individuals. Captive bred animals are already acclimated to aquarium conditions, they are less stressed by transport, and they have a higher survival rate. Importing wild specimens can be tricky and result in higher mortality. Captive bred mantis shrimp from reputable breeders cost $50-100 more on average.
Health & Condition
A strong, healthy mantis is worth paying extra for. Look for signs of good health like full fat reserves in the abdomen, bright coloration, alert activity levels, and intact limbs/antennae. Any signs of poor health or injury will decrease the value. Be prepared to pay premium prices for outstanding condition specimens. Damaged or sickly mantis shrimp should be avoided or heavily discounted.
Reputation of Seller
The reputation and expertise of the retailer or breeder matters. Pay more to buy from specialty aquarium stores or experienced private breeders known for consistently providing healthy, high quality specimens and proper handling. Avoid buying from unknown online sellers or big chain pet stores that may not specialize in marine species.
Cost Breakdown
To give a better idea of the range of prices, here is an overview of what different types, sizes and qualities of mantis shrimp cost:
– Common juvenile specimens ($10-$30)
– Medium juveniles of uncommon species ($30-$60)
– Large juveniles & subadults ($60-$100)
– Adult common specimens ($100-$150)
– Adult medium rarities ($150-$250)
– Adult large rarities & color morphs ($250-$500+)
The record price paid for a mantis shrimp was over $500 for a rare adult harlequin zebra mantis. Prices over $1000 have been seen at auction for exceptional6-8 inch peacock mantis shrimp.
Juvenile Mantis Shrimp
A typical price for a 1-3 inch long juvenile mantis shrimp is $10-$30. This will get you a common species like a brownbanded or zebra mantis. Pet stores and online sellers frequently stock juveniles which are cheaper, but come with some drawbacks. They take 4-6 months to grow to full size and need to be housed alone or with passive tank mates during that time. If you’re patient enough to grow out a juvenile, they represent the most affordable option.
Medium Juveniles
Slightly larger and less common juveniles in the 3-4 inch range cost $30-$60 typically. This size is ideal if you need something larger than a tiny specimen but don’t want to pay adult prices. Some of the more desirable species like peacock mantis may be available as medium juvis at a discount compared to mature individuals. You’ll still need to wait 2-3 months for them to fully mature.
Large Juveniles & Subadults
You can expect to pay $60-$100 for bigger juveniles and subadults around 4-5 inches long. These “teenage” mantis shrimp are enticing because they’re almost full grown, but still a little cheaper than adults. Large juveniles show good coloration but usually lack the giant claws that finish developing at 6 inches. If an uncommon species is available as a large juvenile, it represents a nice compromise.
Adult Common Species
Fully mature adult specimens of common species like zebra, boxer and brownbanded mantis shrimp cost $100-$150 on average. These adults are full sized at 6 inches or more and make impressive display animals. However, the coloration and behaviors of the common species tend to be less exciting than rarer varieties, keeping prices in check. An adult common mantis is the most affordable way to get a big showpiece creature.
Adult Medium Rarities
Uncommon but not ultra rare species in the 6-8 inch adult size range cost $150-$250 typically. Examples are the female ghost mantis (Lysiosquilla tredecimdentata), magnificent mantis (Copilius magnificus) and several Harpiosquilla species. These unique species display more interesting color patterns and behaviors than common mantis shrimp. Their moderately high prices reflect their scarcity and desirability.
Adult Large Rarities & Color Morphs
The most sought after adult specimens like peacock mantis, mischief mantis (Gonodactylellus affinis) and other $250-$500+ species show off vibrant colors and one-of-a-kind looks. Size is impressive at 6-9+ inches for adults. The rarest color morphs of otherwise common species also reach premium prices. These are considered collector’s items and status symbols for their outstanding beauty. Supplies are limited and demand is high.
Factors Influencing Mantid Shrimp Prices
Many factors influence the final price tag on a mantis shrimp. Here are some of the key considerations:
Rarity
How readily available a species is plays a huge role. Common species can be bred easily to meet demand. Rare species from remote coral reefs command prices 10-100x higher because few specimens enter the trade. Newly discovered and imported species often temporarily demand high prices due to scarcity and novelty.
Appearance
Vibrant colors, striking patterns and flashy displays drive up prices. Mantis shrimp with extravagant looks and behaviors simply cost more due to being visual showstoppers. More drab or small species have lower price tags. Rarity and appearance are linked – the prettiest species also tend to be the rarest.
Difficulty of Care
Some species have particular care requirements that increase costs. Delicate shrimp from deep water cost more due to the need for pristine water quality. Species that only accept live foods or have complex social structures require extra effort to keep successfully, which gets reflected in higher prices. Hardy, adaptable species tend to be more affordable.
Size
Larger mantis shrimp and maxed out adults command premium prices. Miniature species are cheaper simply because they’re smaller. Big adults also carry higher price tags because they’re closer to full maturity and their giant claws are intact. Large specimens make the biggest impression in an aquarium display.
Reproduction & Offspring
Due to difficulties breeding many mantis shrimp species, the cost is higher for guaranteed male/female pairs, mated pairs, or juveniles produced from home-bred stock. Proven breeders allow the possibility of generating your own affordable offspring. Wild-caught specimens or unsexed individuals tend to cost less since breeding potential is unknown.
Shipping & Handling
Expensive overnight shipping is often required to safely get mantis shrimp specimens to buyers. Special styrofoam boxes and cold packs keep shrimp alive during transit. Buyers usually pay these shipping fees on top of the listed price per shrimp. Local pickup saves costs when possible.
Purchasing Your Mantis Shrimp
Once you decide on a species and a price range, it’s time to locate and buy your mantis shrimp. Here are some tips:
Sources
Check with saltwater aquarium stores, contact mantis shrimp breeders, or search sites like AquaBid. Join mantis shrimp Facebook groups to find sellers and get guidance. For rare species, get on waitlists from online retailers like Blue Zoo Aquatics that can alert you when stock arrives.
Research Sellers
Buy from experienced, trusted sellers with a history of shipping healthy animals. Read reviews and ask around. Don’t risk buying from unknown sellers just because the price seems better. It’s worth paying more for a high quality specimen you’ll enjoy for years.
Order Early
Give 1-4 weeks lead time for sellers to source mantis shrimp after you order. The more flexibility on options and timing, the better – some species are seasonal. Be patient for the right shrimp at the right price.
Inspect on Arrival
Carefully acclimate and observe new shrimp for signs of health when they arrive. Look for full fat reserves, clear eyes, intact limbs & antennae, and bright colors. Refunds/replacements are sometimes possible on arrivals that suffer serious shipping damage.
Quarantine
Always quarantine new shrimp separately for 4-6 weeks to monitor health. Feed minimally and use a sterile tank with daily water changes. This prevents introducing disease to your main tank. It’s worth the extra space, time and care.
Saving on Costs
Here are some tips if you’re looking to add a mantis shrimp on a budget:
Buy Young Juveniles
Opt for a tiny 1-2 inch juvenile of a common species like Brownbanded or Zebra. These are widely available for around $10-20. Be prepared for slower growth and potential fragility at this small size.
Take Homegrown Specimens
Find a local breeder giving away young mantis shrimp. Home aquarists sometimes get surprise offspring and need to find new homes for them. This can let you acquire species you might not otherwise afford.
Join Swap Meets
Check for local fish swap meets or aquarium society meetings. You may find mantis shrimp at big discounts compared to retail prices – often just a few dollars for juveniles. The downside is limited selection.
Watch for Sales
Retailers sometimes run holiday sales or have temporary promo pricing on certain livestock species. Sign up for store loyalty programs and newsletters to get alerts on mantis shrimp sales. Discounts of 10-25% off can add up on pricier species.
Split Shipping Costs
If buying online, find other local hobbyists to split overnight shipping charges on your shrimp orders. Having your specimens shipped together cuts costs on the bulky, insulated boxes and cold packs required. Just coordinate quarantining carefully.
Trade with Fellow Hobbyists
Participate in local aquarium forums or Facebook groups to find trade opportunities. You can potentially trade corals, supplies, or other livestock to obtain mantis shrimp without having to pay full price. But always inspect anything obtained via trade very closely!
Conclusion
Mantis shrimp are relatively pricey crustaceans, with costs ranging from $10 for tiny juveniles up to $500+ for prized adults of rare species. Factors like rarity, appearance, size, and breeding potential drive prices higher for the most extraordinary species and color morphs. With some careful shopping and planning, hobbyists can find great deals on these amazing marine animals. While not cheap, their gorgeous colors, behaviors and intelligence make mantis shrimp well worth the investment.
