Since the end of 2018, more and more chinese aquarium hobbyists show interest on the chinese local fish. Some of the local fish, which used for food are now included in the list of ornamental fish. we hope our particular biotope aquarium can show the beauty of chinese local fish to the world.

The hill streams of the North Zhejiang Grand Canyon is taken as the sample of our particular biotope aquarium. Fish living in this aquarium include Opsariichthys evolans,Acrossocheilus labiatus,Cobitis taenia and Acheilognathus rhombeus. They live together in harmony, every one is taking its particular niche.

Aquarium description

Set-up date
May, 2020
Aquarium decoration

There are lots of plankton in the hill steams of the North Zhejiang Grand Canyon. It makes the color of the water slightly green. Therefore, the green light is used in our biotope set-up to make it looking like a natural biotope.

This particular biotope set-up contains: 12 Opsariichthys evolans,7 Acrossocheilus labiatus,18 Cobitis taenia and 3 Acheilognathus rhombeus.

Aquarium equipment

Our particular biotope aquarium is a 1.2m fish tank consist with stones, sands, gravel, woods and other biological components.

Fish care

The inhabitants in such a biotope tank need both shady area and open area. When the fishes are threathened, they will hide themselves in the shady area. In the rest of the time, the fishes prefer to stay in the open area.

Fishes:

  • Opsariichthys evolans 12
  • Acheilognathus rhombeus 3
  • Acrossocheilus labiatus 7
  • Cobitis taenia 18
Plant care

Vallisneria natans can be taken as the food for the fish. Rabdosia serra and Ludwigia prostrata is used for creating shady area to the fishes.

Wetland plants:

  • Vallisneria natans 8
  • Rabdosia serra 6
  • Ludwigia prostrata 5
Water care

The temperature should be around 23℃。
The PH of our particular biotope aquarium is 6.2. The PH of the hill steams of the North Zhejiang Grand Canyon is lower than 7. In order to decreased the PH of our particular biotope aquarium, the driftwood is used in the fish tank.

At the same time, we make waves on the water surface to increase the dissolved oxygen in the water and make the fish more comfortable.

Comment by the expert

Fan Li: The aquarium is a bit crowded. The Acrossocheilus is aggressive and can attack other fishes when they are in adult size.

Zhou Hang: The driftwood and aquatic plants do not match with BIN. The biotope is a very open river, receives strong sunlight, hardly any aquatic plants because of the rocky bottom. Acrossocheilus is quite aggressive and territorial in the wild, maybe can try reduce the fish and provide more terittories.
