Tank for the 125l aquarium example

The aquarium used in this 125l aquarium example is the Juwel Rio 125 LED. This convinces with a timeless but nevertheless chic design. Due to the shape of the tank, it is ideal as a room divider eye-catcher, but also quite normal on the wall. In addition, it is possible to buy this aquarium with a base cabinet, so that the tank and base fit perfectly together.

Aquarium equipment


The scope of delivery of the aquarium already includes an internal filter. This is completely sufficient to operate the aquarium. As an alternative, however, the JBL CristalProfi e702 can also be installed. This filter is an external filter and therefore brings some advantages. In the aquarium itself no filter disturbs the appearance. Only the inlet and outlet pipes are visible. However, these can be completely covered with stones or roots, so that nothing is visible. In addition, this filter is also quiet, so that use in the bedroom or in another quiet room is possible.


To illuminate the plants, this aquarium does not require extra lighting. Because in the scope of delivery of the tank are already LED tubes, which are installed in the lid. Thus, they do not interfere with the appearance. In addition, this lighting is quite sufficient to operate the tank.


The heater included in the scope of delivery can be used as a heater for this aquarium. However, if an external filter is installed, you can use the JBL ProTemp E300 flow heater as a heater. This is particularly convincing in that it is completely invisible. It is installed between the external filter and the inflow hose. Through this heater it is possible to increase the water temperature to above room temperature. This is necessary for the fish to feel comfortable in the tank.

Animals for the 125l aquarium example

Dwarf Gourami

Dwarf gourami are, as the name suggests, rather smaller gourami. Nevertheless, these fish enchant with their special appearance. With their attractive coloration, they amaze everyone who looks at them. Despite their size, only a pair (1M + 1W) or a trio (1M + 1W) should be kept in this aquarium.

Mosquito danios

Mosquito danios are very attractive fish. Especially their red coloration stands out. Often you can find them in rather smaller nano tanks. But also in large aquariums and especially in a larger group these fish come out very nicely. Therefore, a group of about 15 should be used in this tank.

Dwarf shrimp

With dwarf shrimp can breathe life into any aquarium. Due to the fact that these animals come in a variety of colors, everyone can find a suitable species for themselves. In addition, dwarf shrimp play an important role in the aquarium. They keep it clean and process waste in the tank. It is enough to put 20 animals in the beginning, as they will multiply anyway.

Staghorn snails

Staghorn snails, as the name suggests, have several spines on their shell. This makes them look extremely interesting upon closer inspection. But in addition to their appearance, they bring an important feature to the aquarium. These snails help keep the aquarium clean and rid it of algae. At this tank size can be used about 5-6 specimens.
