General Impression/Faithful Reproduction of Biotope:
This is a very nice biotope aquarium. The only issue with the display is an issue of scale. There is a lot going on in this tank that would not likely be a natural distribution of animals and hardscape in the natural habitat. If a glass box of this size were set on the bottom in this stream would it capture everything that can be seen in the display? This is a common error in a biotope aquarium for competition... it is too 'scaped' and suffers from a problem with scale. A section of the habitat 100x larger than the tank itself is what is seen in the display.

Other than that... magnificent!

Well done! If I could suggest an improvement it would be to concentrate more on one or two species of fish and have larger schools of those rather than more species with fewer numbers of each. I think it is wonderful that you collected them yourself and that may have been the deciding factor but a larger school of one species would be more impactful. Good work with the powerheads!

Materials The photos I took before, lacking agility and substitution, can only show a moment of the underwater landscape in the aquarium. When I made this biotope aquarium, I had an idea of expressing the real flowing underwater landscape in a static photo by swinging of underwater plants through water flow. Therefore, I installed two strip-shaped wave pumps in the aquarium and hid them under the shelf made of driftwood. Thanks to the blow action (blowing function) of the water pump, the underwater plants sway with the current, and the fish swim against the current, just like what they do in their natural habitat. All the elements used in my aquarium, including branches and fallen leaves, were derived from natural collection. I chose white fine sand as the substrates which is consistent with that in the habitat.
Additional Information water change twice a week (1/4)
