Fish for your aquarium

What would an aquarium be without fish? Even though aquariums with colorful aquatic plants in red, green, brownish and yellow hues, or pure shrimp tanks with their lively bustle, are real eye-catchers, stocking fish in a suitably large tank is still the icing on the cake.

Even in an elaborately designed aquascape, a suitable school of fish is the crowning touch, looking like a flock of birds moving across a natural landscape. But in more conventionally decorated aquariums with lots of aquatic plants, the interplay of flora and fauna is also fascinating to watch, and both sides benefit greatly from each other in biological terms as well. Plants supply fish and other aquarium inhabitants with oxygen and provide hiding places, spawning sites and grazing areas for feeding. Fish and other aquarium animals exhale carbon dioxide, and through this gas and their other excretions they supply nutrients that are in turn used by the plants. In a closed system such as an aquarium, this cycle forms a functioning ecosystem.

Are you looking for the right fish for your aquarium or aquascape? We are happy to help you choose suitable fish for your aquarium. In this section of the Aquascaping Wiki, we introduce various fish species and genera, such as tetras, discus, catfish and rasboras, to name just a few. Many species of plants and animals, for example from South America or Asia, prefer the same water parameters: soft, acidic water.
When presenting the fish species, we always consider their compatibility with planted aquariums and aquascapes, because not all fish are suitable for aquariums with aquatic plants. Some fish species may see aquarium plants as food, while for others the water parameters and conditions in an aquascape may not match their care requirements. Nevertheless, there are a large number of exotic fish species that are well suited to a planted aquarium.
