With this 180L aquarium I wanted to have a slice of nature, in my home. I wished for a green part of aquatic life, a reminiscence of the spring and summer, existing in my home during the cold and dark months of winter. Sharing it with my friends and my family, was a joy for the soul.

The beauty of a floodplain and it’s simplicity, I believe it makes a great subject for a simple but effective biotope aquarium. The natural aquatic beauty that I have loved, all my childhood life, I have slowly seen it diminishing in front of my eyes. It’s not completely gone but what a better way to keep it close, than just to preserve a part of it in the form of an aquatic biotope.

All the material used in this aquarium, sand, rocks, driftwood, plants, snails and fish came from one single location, directly from the floodplain.

Aquarium description

Set-up date
August, 2022
Aquarium decoration

I wanted to add in my setup rock structures that can be found at the base of a flooded levee, and to mimic the geography of a floodplain, with parts that have low water depth and higher water depth.

The clear water, filtered by the floodplain plants and the clean fine sand glowing under the strong sun rays of summer, are real traits to the natural biotope, and those can create an unexpected natural exotic underwater look, to a rather more temperate climate habitat. Also, all types of algae are welcome as they are an important part of nature.

That is the view I wished to capture in my biotope aquarium. Species like Syngnathus abaster, the lower Danube pipe fish, can accentuate the feeling of a tropical view and also it’s ancient look and interesting biology reminds of the marine origins of its’s kind.

Aquarium equipment

Internal sponge filter with a strong powerhead, chinese brand.
Very bright LED shop lights.

Fish care

Weekly water changes, frozen and live foods for feedings and a good strong flow that mimic the water current found in their natural habitat. Mostly I made the biotope thinking at a number of species that found their breeding grounds in the floodplain, mainly Rhodeus amarus and Syngnathus abaster.

Fish list:

  • Syngnathus abaster (Syngnathidae)
  • Rhodeus amarus (Cyprinidae)
  • Proterorhinus semilunaris (Gobiidae)
  • Knipowitschia caucasica (Gobiidae)
  • Cobitis elongatoides (Gobiidae)
  • Babka gymnotrachelus (Gobiidae)

Mollusc list:

  • Esperina esperi (Melanopsidae)
  • Viviparus viviparus (Viviparidae)
  • Theodoxus fluviatilis (Neritidae)
  • Theodoxus danubialis (Neritidae)

 

Plant care

Trimming once a month and giving them very strong LED light. No CO2 and no fertilisers have been used.

Aquatic vegetation:

  • Potamogeton perfoliatus (Potamogetonaceae)
  • Eleocharis acicularis (Cyperaceae)
  • Potamogeton pectinatus (Potamogetonaceae)
  • Potamogeton friesii (Potamogetonaceae)
  • Vallisneria spiralis (Hydrocharitaceae)
  • Myriophyllum spicatum (Haloragaceae)
Water care

Water change done weekly.
