Wild individuals can be found in marginal backwaters next to tiny waterfalls and cascades, as well as in swift-moving streams with a flow rate of over one meter per second.

Description

Adults grow to a length of 5–6 cm. Large, rounded paired fins on Sevelia raznina’s flat body greatly enhance its surface area and aid in its ability to cling to stones and thwart current flow.

The species’ contrasting pattern of lines and dots in shades of brownish-yellow is one of its defining characteristics.

It is important to note that as they get older, the fry’s body shape and "flattening" become more recognizable to fish.

Behavior and compatibility

Friendly and peaceful species. Get along well with family members and fish that can withstand choppy waters. You can think of Nemacheilidae loaches, Danio, Rasbora, Akisis catfish, and other fish as neighbors if you do not make an excessively strong flow.

Since fish typically inhabit large groups, buying five or six of them is thought to be preferable.

Cannot be reconciled with species having lower territoriality.

In a nutshell:

• Aquarium volume – from 70 l.
• Temperature – 20-24 ° C
• pH value – 6.0-7.5
• Water hardness – mostly soft (2-12 GH)
• Substrate type – any
• Lighting – subdued
• Brackish water – no
• Water movement – weak or moderate
• Fish size – 5-6 cm.
• Feeding – any food containing plant components
• Temperament – peaceful
• Keeping in group of 5-6 individuals

An aquarium with five or six fish should be no more than seventy to eighty liters. It’s a straightforward design. The lower tier is the focus of attention. The substrate consists of large stones, boulders, and snags that are fixed in them. Usually, there is no aquatic vegetation. Sometimes, mosses, ferns, and plants that can endure a strong current are planted where they can grow on a hard surface like stone or wood.

In the "Aquarium plants" section, you can choose the required species by using the filter’s corresponding parameter, "Can grow on snags, stones, etc. p."

It is advised that there be a current. There is a maximum flow rate of 15-20 times per hour, t. In an aquarium with 70 liters, the pump or filter needs to circulate at least 1000 liters per hour. If different kinds of fish are housed together, a gentler current is also permitted.

Sevelia razlivanova requires oxygen-rich, clean running water. It is worthwhile to select a filter model that can handle aircraft water in addition to its primary use of purifying water. If not, you’ll have to buy an aerator separately.

Standard aquarium maintenance entails a number of required steps, such as clearing the soil of organic waste, replacing a portion of the water with fresh water each week, and doing routine equipment maintenance.

Feeding

In the wild, they eat the algae that forms on stones, the microorganisms that live there, and small invertebrates. Special plant-based food is used in home aquariums in the form of gels and briquettes that can be fixed to the bottom.

In a strong current, common flakes and granules will be carried away by the flow and quickly settle in the filtration system, where they will undoubtedly cause pollution in the water.

Breeding / reproduction

Numerous accounts exist of this species being successfully bred domestically. A group of several fish is sufficient for breeding, and it is likely that at least one of the fish will be a female.

It is advised to spawn in a different tank if there are nearby fish. Using large river gravel in the design is advised. The eggs will eventually settle in the numerous cracks and spaces between the stones that make up this kind of substrate. The adult fish can unintentionally eat their own fry when they are too small, so the emerging fry can hide in these shelters from them. Furthermore, organic waste will gather in the cracks and serve as a significant food source.

To ensure adequate dissolved oxygen content and water movement, the spawning aquarium ought to be fitted with one or more sizable airlift filters featuring a sponge. The low chance of fry getting drawn into the filtration system is one of this filter’s benefits over others.

The water’s gradual rise to 25–26 °C serves as the spawning stimulus. After 5–6 days, it is required to replace a portion of the water with cooler water that is between 19 and 20 °C (this can be done in conjunction with aquarium cleaning). The start of the rainy season is thus mimicked. Additionally, the temperature is kept in the vicinity of 20 °C, which is the lower bound of a comfortable range.

After some time, spawning ought to start. The precise incubation period is unknown since the eggs are concealed between the stones and the fry that initially appeared have stayed in place.
