Aquarium decoration

A center piece of my decoration is the plants growing above the water level, trying to imitate the bank of a small forrest stream. The plateau, of which the plants are growing, are made of roots and small rocks, on which there is a layer of peat. This is decorated with small branches to imitate the look of a rooted water surface. Those two plateaus are making ideally hiding spots for the Apistogramma trio.

Two large roots are balancing the look of the aquarium. On the right side the fern is providing shade and cover for the Apistogramma male, which likes to hide in the shadows. The shaded look is providing both cover and protection, and trying to imitate the jungle, crowding down to the bank of the stream.
The substrate is a mix of sand, gravel and small pebbles. Underneath this there is a layer of substrate, which is helping to keep the pH in level.

Dead leaves, branches, roots, pebbles, alder cones, peat and a single nut-shell is imitating the messy substrate of a small forrest stream.
The color of the water is colored black to make it look like wellknown Southamerican blackwater.

Filtration: Fluval 207 cannister filter – 780 L/h.

Lightning: two IKEA Nymåne lamps with some special Osram Parathom GU10, 550 lumens 4000 k, LED spots. The spots are trying to imitate the single sun rays penetrating through the water of the forrest stream.

Others: Eheim Skim 350 surface skimmer.

Comment by the expert

Roberto Reis: Beautiful aquarium, based on one video showing most of the tank and surroundings. Good description of equipments and other details.

Francesco Denitto: Very nice BAM. The hobbyist took care of many details showed in the aquarium. Just a small criticism: BIN is characterized by a strong water current which is not represented in the aquarium.

Donald C. Taphorn: For a biotope tank I expect more than two species, but these two are characteristic and quite beautiful.
