The absolute star of the biotope aquarium from Rio Jufaris, decorated by Heiko Bleher,  is Hemigrammus bleheri together with other small tetras like Paracherodon simulans, Copella nattereri, Hyphessobrycon erythrostigma, dwarf cichlids and small catfishes, that live together in harmony, every one taking its particular niche.

Aquarium information

Aquarium description

Set-up date
september 2011
Aquarium decoration

There is much leave-litter over the fine beige coloured sandy ground, and very little flow.

This particular biotope set-up contains: 100 Hemigrammus bleheri, 200 Paracheirodon simulans, 20 Otocinclus arnoldi, 15 Corydoras julii, and 8 Dicrossus filamentosus. Other species from the list could be a good alternative or addition as aquarium mates.

Aquarium equipment

It is suggested a good canister filter with peat moss and other biological components. Lighting should not be very bright.

Fish care

The inhabitants in such a biotope tank do also need a shady areas, which can be created using the floating plants and driftwood.

Plant care

The plants are: Echinodorus horizontalis, Cabomba furcata, Myriophyllum brasiliensis, Azolla and Salvinia species. Important is to give the fish the shady areas, maybe with the floating plants and driftwood.

Water care

The temperature should not exceed 29 °C, the pH can be around 6 but should not be ever above 6.5, and the conductivity as low as possible, try not to have it over 100 μS/cm – always the lower the better.

Comment by the expert

This biotope aquarium is imitating the bank of the creek. It was decorated by Heiko Bleher at the Napoli Aquatica Exhibition in 2011, with the species living together in the same habitat. And, what is very important, in the quantity that lives in such a biotope, which is normally not done correctly and therefore this amazing effect, this fantastic behaviour, cannot be seen.
