Aquarium decoration

The composition of this aquarium was based on the concept of recreating a bedrock structure where various parts of the rocks emerge from the water, resembling the flat surfaces where loaches naturally reside. Smooth-textured stones with large crevices were carefully selected to form a cohesive structure, giving the impression of a single unified formation. A central rock was chosen strategically to conceal the entrances and exits of the filters and WaveMaker, ensuring that water flow initiates from this point without interference. This design allows the full power of the filters and WaveMaker to be evenly distributed across the flat and horizontal surfaces of the other rocks in the aquarium.

In contrast to their natural habitat, dark spots were intentionally created using loose stones, providing hiding spots where loaches can seek refuge if they feel stressed by external factors within the aquarium.

Aquarium equipment

• Water pump: SunSun JVP-120 WaveMaker, 3000L/H
• Lighting: Chihiros B Series 60cm

Fish care

The care of the fish primarily focuses on their diet. Since these loaches naturally feed on algae, detritus, biofilm, and small microorganisms found on the surfaces of river rocks, gel foods were placed on flat rocks in this biotope to replicate the feeding behavior of Sewellia lineolata in their natural habitat. To encourage the growth of algae and biofilm, an 8-hour light cycle was established, with the lights at full intensity for 4 of these hours.

Additionally, small rocks were placed in a barrel with botanicals and exposed to sunlight to promote natural algae and biofilm growth.

It is noteworthy that the loaches became extremely active upon introducing these new rocks to the biotope, quickly positioning themselves over the stones to feed. Every other day, freshly hatched brine shrimp were introduced, and the strong current in the tank allowed the shrimp to settle in the crevices of the rocks, where the loaches would feed.

Any leftover brine shrimp were drawn to the light of the aquarium lamp, attracting the loaches to the glass where they would gather to feed. These fish are somewhat shy, making it challenging to see all 12 individuals at once, but this also creates great excitement as they emerge one by one or in small groups to feed frenetically.

Plant care

Water care

The maintenance of this aquarium included weekly water changes of 30%, during which the front glass was cleaned to remove algae. The aquarium filter was inspected monthly, focusing on cleaning the mechanical filtration components to ensure optimal operation.
