Habitat

It is not natural for something to be considered "artificial." Additionally, different wild Caridina cantonensis populations can be found throughout Hong Kong, including hidden among vegetation and in river backwaters with mild currents.

Description

Rich, contrasting stripes of black and white or red and white with clear edges are painted on the Crystals’ bodies. Shrimp cannot be distinguished until they are sexually mature.

Female adults have a curved abdominal line and are larger overall. Because the eggs are nearly invisible because they are red, it is challenging to identify the female by the saddle.

Men can grow to be 2.5 cm long, while women can reach 3 cm.

Crystal Classification

Red and black crystals fall into the following classes: S+, SS, S-higher, A, B, and C-lower.

The amount of white space and the color saturation determine the class. Transparent or translucent regions of red or black color are seen in shrimp of lower classes. Crystals can change color, rising or falling one classification point, depending on the keeping conditions.

The color of the rostrum, abdomen, cephalothorax, and caudal fin determine which class a fish belongs to.

Highest class SSS

Shrimp are a rich white color with a few tiny red spots on the shell. Some people’s abdomens have red dots. Exclusive forms, such as crowns or flowers, are occasionally bred in Japan with a unique shaped spot on the shell.

Class SS

White shrimp with a possible white spot on their red shell. The shrimp’s name is determined by the shape of this location. Shrimp in this class have a solid white tail, rostrum, and abdomen; the latter may have tiny red dots shaped like a v that stop short of the edges.

Class S+

There is very little red on the shell; the tail and rostrum are white. Color boundaries are distinct. There are white spots on the narrow red stripes that run along the edges of the abdomen, and the v-shaped red spots extend to the edges of the abdomen. more white in appearance.

Class S

The shell is mostly red, with a red rostrum as well. The abdomen has saturated white stripes. The color of the shrimp is visually striking, with no areas that are transparent.

Class A

Shrimps belonging to the first lower class exhibit a decrease in color intensity and have less bright and uniform color, even though the red stripes on their belly have distinct boundaries. The rostrum and tail are red. On the white stripes, there are visible transparent sections, particularly where the colors meet.

Class B

There is a lot of transparency on the white stripes, the red stripes on the belly are uneven, and the tail fin and rostrum are reddish.

Class C

There is not much red on the tail or rostrum; they are translucent. The thin, unevenly painted white stripes on the belly have the potential to be totally transparent. There are a lot of transparent spots and poor painting in the red areas. There is instability in the number of colored stripes.

Arrangement and parameters of the shrimp tank

Due to their high requirements, only seasoned aquarium keepers should attempt to keep crystals. Higher class shrimp are particularly erratic; even the smallest variations in temperature or water composition can cause diseases, mass mortality, or color changes.

It is necessary to have a small aquarium, no bigger than 10 liters, with a sizable bottom area. Any small, neutral substrate will work. Shrimps need a lot of driftwood in their living area, ideally mangroves and stones. More plants are preferable. As the primary source of food for Crystals, they organize the area and create dead biomass. When pruning fast-growing forms in the shrimp tank, only low-growing plant species are planted to minimize interference. Certain plants release juices that are toxic to shrimps during this process.

The water’s chemical composition should not be altered by the natural metabolism of vegetation because this would severely harm the crystals. Ideal plants include a variety of ferns and mosses, pistia, hornwort, carpet algae like cladophora, and floating and ground cover plants. Although anubias and cryptocorynes are undesirable in the shrimp tank, if they are present, their leaves—especially the internal roots—should not be removed. Toxins released by cut plants cause a mass death of shrimp in a matter of days.

Water parameters: pH 6.5–7.5, GH 4-6, kH 1-2, and 21–26°C.

Ideal acidity 6.5-7; low classes are comfortable with higher hardness levels of 8–14 and acidity levels of 7–7.5; the highest classes, on the other hand, need soft water, 1-3, and they can’t stand sustained temperature increases.

The stability of the parameters must be closely watched; even slight variations in the allowable indicators negatively impact the health of the Crystals (Caridina cf. cantonensis sp.).

Installing a heater, aerator, and filter is essential. There is constant aeration even with the filter intake tubes closed. Every week, one-third of the water with the same specifications as the aquarium is replaced.

It is not possible to keep Crystals from different classes together, particularly with shrimp from different species in this genus. Uncontrolled crossing will cause the species’ purity to disappear.

Nutrition

Crystal power supply – algae. Healthy shrimps constantly move around the aquarium in search of food. If there are a lot of plants, they will most likely have enough food, otherwise you can feed them with specialized high-quality plant-based food, less often treat them with frozen cyclops, daphnia and brine shrimp. They happily eat spinach leaves, Indian almond, oak, apple, peach, ash, hazel and mulberry, pieces of fruits and vegetables. The latter should be washed well and boiled a little to get rid of the nitrates they contain. You can put willow and alder driftwood in the shrimp tank and the crystals will eat the decomposed top layer with appetite.

Shrimps cannot be overfed protein-rich foods because they cannot process and absorb them in large enough quantities. But, they should consume food within 30 to 60 minutes because too much of it is unhealthy for them. To prevent water pollution, the remains are taken out of the aquarium.

White Crystals are lost due to poor nutrition and either turn transparent or take on a grayish-yellow hue. On the other hand, foods high in iron and minerals support the preservation of a deep contrast in color.

Caridina cf. cantonensis, the scientific name for Red and Black Crystal Shrimp, is a truly beautiful addition to any aquarium. They’re a unique option for both new and seasoned shrimp lovers because of their vibrant colors and complex patterns. Their vivid colors give your tank a sense of dynamic beauty in addition to adding visual interest.

It takes some attention to detail to take care of these shrimp, especially when it comes to the parameters and quality of the water.

Additionally, they gain from a varied diet because it keeps them healthy and brings out their color.

Observing the behavior of Red and Black Crystal Shrimp is one of the pleasures of owning them. These shrimp are gregarious and lively; you can frequently see them foraging and interacting with their environment. Their presence can infuse your aquarium with a vibrant and captivating dynamic that will captivate you for hours as you watch what they do.
