El ghost shrimp, also known as crystal shrimp (Palaemonetes paludosus), is one of the most popular freshwater shrimp species among aquarists. Originally from Asia and coastal areas, these invertebrates inhabit the bottoms of rivers with well-oxygenated water, especially in areas with abundant vegetation near the banks of streams.
These shrimp have earned their name thanks to their almost transparent appearance, which gives them very effective natural camouflage. However, their transparency can vary depending on factors such as food and water quality, and may present shades brown, green or even blue.
Physical appearance and size
The body of the ghost shrimp is cylindrical and slightly curved downwards, as is the case with other crustaceans of the Decapoda order. Its claws, although small, are quite agile and play a key role when collecting food in the aquarium. Its size ranges from 5 and 10 centimeters, depending on the quality of care received.
The life expectancy of these invertebrates is approximately two years, although under ideal conditions they can live a little longer. It is important to provide them with a suitable environment to maximize their longevity.
Ideal parameters for your habitat
The aquarium environment is a determining factor for the health and well-being of ghost shrimp. Optimal parameters include:
- Temperature: Keep the water between 22 and 28 degrees centigrade. This ensures a warm and suitable environment for your metabolism.
- pH: Must be between 6.5 and 7.5, slightly acidic or neutral.
- Water hardness (GH): Between 7 and 15, preferably at medium levels.
In addition, the water must be well oxygenated and free of contaminants such as ammonia or nitrites. The use of filters and regular partial water changes is essential to maintaining a healthy aquarium.
While these shrimp tolerate variations in water conditions, they are especially sensitive to chemicals such as copper, common in some fish medications. Therefore, it is advisable to handle treatments in separate aquariums.
Feeding the ghost shrimp
One of the simplest aspects of ghost shrimp care is their feeding. These invertebrates are omnivores and scavengers, capable of consuming almost any type of food available in the aquarium. Some common choices include:
- Fish food: In the form of flakes, tablets or porridges.
- Blanched vegetables: Vegetables like zucchini o spinach, ideal for offering them an extra supply of nutrients.
- Microscopic organisms: Detritus and suspended particles found at the bottom of the aquarium.
El smell These shrimp have a highly developed diet, allowing them to quickly locate food. Although they are excellent aquarium cleaners, they can compete with other inhabitants for food, so it is key to ensure they receive a sufficient amount of food. Diet balance.
Behavior in the aquarium
In terms of behavior, the ghost shrimp is peaceful with fish and other invertebrates, but they can hunt fry and larvae if they have the opportunity. For this reason, it is important not to place them in aquariums where they coexist with developing fish, unless the necessary measures are taken to separate them.
Males may show some territorial aggressiveness each other, especially in the presence of females, which highlights the need to provide them with adequate space with vegetation, logs and caves where they can hide.
A tank of at least 1000 litres is recommended. 40 liters to prevent overcrowding and ensure that each shrimp has enough room to move and shelter.
Reproduction
Breeding ghost shrimp in captivity can be challenging, as their larvae require Brackish water to develop properly. Females are smaller than males, making them easier to identify.
The reproductive process usually begins with the release of larvae into the water, which require additional care. This makes their reproduction difficult in a standard freshwater aquarium.
The ghost shrimp is not only an attractive option for aquarists because of its appearance y unique behavior, but also for their ability to keep the aquarium clean. With proper care, these small invertebrates bring vitality and functionality to any aquatic environment.
