Comment by the expert

Alexey Malyshev: Good job, especially species diversity. But why are there no plants?

Gireg Allain: Nice realization, especially when it comes to the placement of pieces of wood that create safe shading areas. Too bad there are no plants, yet present in the natural environment. Beware, Pseudorasbora parva is an invasive species that we should not find in this aquarium. As for the chubs, Squalius cephalus, they have no place here. They are fish that reach 60 cm! Careful with the filtration, there’s a lot of suspended sediment. This is still a nice aquarium, bravo!
