Aquarium shrimp can add vitality and interest to freshwater tanks. Two of the most popular shrimp breeds kept by aquarists are whisker shrimp and ghost shrimp. But what are the key differences between these transparent crustaceans?
Read on as we compare whisker shrimp vs ghost shrimp including appearance, behavior, care needs and suitability for home aquariums.
An Overview of Whisker Shrimp and Ghost Shrimp
First, let’s introduce the two types of shrimp:
Whisker Shrimp – Whisker shrimp (Macrobrachium species) are larger shrimp native to Southeast Asia. They are also called bamboo or flower shrimp. Whisker shrimp get their name from their long “whiskers” or antennae.
Ghost Shrimp – Ghost shrimp (Palaemonetes species) are small, pale freshwater shrimp native to North America. They are virtually transparent, giving them a “ghostly” appearance. Ghost shrimp are inexpensive and commonly sold as feeder shrimp.
Both whisker shrimp and ghost shrimp make interesting additions to freshwater community tanks. But there are some notable differences between them we’ll explore in this comparison.
Size and Appearance Differences
One of the biggest differences between whisker shrimp and ghost shrimp is their size and visibility:
- Size – Whisker shrimp reach 2-3 inches in length. Ghost shrimp max out around 1 inch and are often smaller.
- Body Color – Whisker shrimp have an opaque body ranging from tan to dark brown. Ghost shrimp are translucent with a faint greyish tone.
- Markings – Whisker shrimp have conspicuous bands and dots. Ghost shrimp lack any markings aside from tiny black eyes.
- Eyes – Whisker shrimp have stalked eyes that swivel. Ghost shrimp eyes are recessed and fixed in place.
- “Whiskers” – Both shrimp have long antennae, but whisker shrimp antennae are especially prominent, giving them their name.
So in summary, whisker shrimp are noticeably larger with bolder colors and markings compared to the petite, see-through ghost shrimp.
Behavior Differences Between Whisker and Ghost Shrimp
In addition to physical differences, whisker shrimp and ghost shrimp exhibit some general behavioral differences:
- Activity Level – Whisker shrimp are mellow and lumbering. Ghost shrimp are very active, darting around speedily.
- Temperament – Whisker shrimp are peaceful toward tankmates. Ghost shrimp can be more aggressive, especially to small shrimp.
- Hiding – Whisker shrimp spend more time openly grazing. Ghost shrimp tend to hide frequently, especially without plant cover.
- Hardiness – Both species are quite hardy, but ghost shrimp are expendable feeders. Whisker shrimp are more prized.
- Diet – Whisker shrimp are omnivores and scavengers. Ghost shrimp are primarily scavengers that eat microorganisms, plant matter and algae.
So in general, whisker shrimp have a calmer demeanor and eat a broader diet compared to energetic little ghost shrimp.
Comparing Care Needs and Tank Suitability
Caring for these popular shrimp also involves some key differences:
- Minimum Tank Size – Whisker shrimp need at least a 20 gallon aquarium due to their larger size. A 10 gallon tank can house ghost shrimp.
- Water Parameters – Whisker shrimp prefer soft, acidic water. Ghost shrimp are very adaptable to a wide pH range.
- Plants – Whisker shrimp appreciate planted tanks. Ghost shrimp absolutely require plant cover to feel secure. Floating plants are ideal.
- Substrate – Whisker shrimp dig less than ghost shrimp, so fine substrates are not mandatory.
- ** Tankmates** – Both shrimp can coexist with small community fish. Avoid housing with aggressive species that may attack shrimp.
- Breeding – Ghost shrimp readily breed in home aquariums. Whisker shrimp are challenging to breed in captivity.
- Lifespan – Ghost shrimp live just 1 year generally. Whisker shrimp can live 3-5 years with proper care.
So in summary, whisker shrimp require pristine water quality and ample space, while ghost shrimp are lower maintenance. Now let’s wrap up the key points.
Conclusion: Which Shrimp is Better For Your Aquarium?
When choosing between whisker shrimp or ghost shrimp, keep these summary points in mind:
- For large planted tanks – Whisker shrimp are the best choice given their 2-3 inch size and need for swimming room. They also appreciate planted setups.
- For small community tanks – Ghost shrimp are better suited to nano tanks since they max out around an inch and have lower care needs.
- For kids’ or beginner tanks – Ghost shrimp are the foolproof option here given their hardiness and adaptability to a wide range of water conditions.
- For short lifespans – Ghost shrimp live just one year generally, so are not a long term commitment. Whisker shrimp can live 3-5 years with proper care and conditions.
- For visible activity – Whisker shrimp spend more time grazing out in the open. Ghost shrimp hide often unless provided ample plant cover.
- For breeding interest – Ghost shrimp readily breed in home aquariums while whisker shrimp are challenging. Breeding ghost shrimp can be an interesting learning experience.
By understanding the key differences in appearance, behavior, and care between whisker shrimp and ghost shrimp, you can decide which is better suited to your particular freshwater aquarium setup.
