Gymnogeophagus australis is a fish living as a couple or in a group naturally found near the bottom. This species is omnivorous . Naturally, it tends to dig into the sand and transform its environment.

Although slightly territorial, Gymnogeophagus australis is a rather peaceful animal that generally behaves in a peaceful manner with other species. It should be noted that it is sometimes less tolerant with its conspecifics. Parades or even small jousts may occur between different members of the group until a hierarchy is established.

Main recommendations for fishkeeping

Deontology

In order to preserve wildlife, if you acquire this animal, it must not be released into the wild. See also, the Fishipedia charter.

Fishipedia supports the practice of responsible and environmentally friendly aquarium keeping. We encourage maintenance if it is motivated by a desire to understand the biological functioning of living things and if it is done with respect for animal life.

We believe that aquaristics is an opening to the discovery of aquatic environments, especially freshwater, and that this knowledge is necessary to better protect and respect these environments. Logically, we refute the compulsive purchase of animals that would not find a sufficient and / or adapted place in the host aquarium.

Our recommendations

    400 liters

Cohabitation & Environment

In a community aquarium context, this species should be kept in a minimum volume of 400 liters.

Fearful by nature, it is advised not to let Gymnogeophagus australis cohabit with large territorial species or with too aggressive fish. It can easily evolve with territorial neighbors with a peaceful temperament or with non-territorial species.

Be careful to plan an adequate space for each territorial species. Each species should have a surface and a decor allowing it to juxtapose its territory with that of its neighbors.

Gymnogeophagus australis is a fish that generally lives in groups outside of the reproduction periods. If you want to reproduce them and have a good chance of forming a couple, it is recommended to keep at least 5 individuals.. In a community aquarium, the chances of survival of the larvae are almost null. After a few spawns, it is preferable to isolate the couple or to separate from the other members of the group.

The hierarchical organization and the aggressiveness between fellow fish can weaken certain individuals, the presence of hiding places becomes then necessary. If you wish to add new members, it is better to introduce younger fish. They will have a better chance of integrating into the new balance.

The species enjoys a particularly vegetation-rich environment. The addition of plants will provide many useful hiding places for resting. These areas are also conducive to possible breeding in the aquarium.

Tips for feeding

Gymnogeophagus australis is omnivorous.

This species can eat dry food (flakes, pellets), fresh food and frozen food. To avoid deficiencies, it is recommended to vary the types of food.

You should not overfeed your residents to avoid polluting the water. For most species, it is better to feed a few small portions each day rather than one large meal.
