Dwergkogelvissen: A Comprehensive Guide to Keeping and Caring for These Unique Fish

Are you looking for an interesting and unique fish to add to your aquarium? Look no further than the Dwergkogelvissen, the smallest kogelvissoort in existence.

Known for their greenish-brown color and bobble-like belly, these fish are both fun to watch and challenging to care for. In this article, we’ll provide an overview of their natural habitat, appearance, necessary aquarium conditions, feeding habits, behavior, and breeding habits.

Natural Habitat

Dwergkogelvissen are primarily found in the Pambarivier in the southwest of India. Unfortunately, deforestation, urbanization, and overfishing have left these fish vulnerable to endangerment.


Dwergkogelvissen are a relatively small species of fish, measuring in at only a few centimeters in length. They have a greenish-brown color and a white or yellowish belly.

They are known for their distinctive bobble-like belly, which is more pronounced in males than it is in females. It is also worth noting that males tend to be slimmer and have more pronounced ventral fins.

Necessary Aquarium Conditions

In terms of aquarium conditions, Dwergkogelvissen require a minimum tank size of 40 liters. They also prefer heavily planted aquariums with plenty of hiding places.

Additionally, they do well alone or with small, fast-swimming tankmates. Finally, it is important to provide them with a territory marker item such as stones, shells, or wood.

Feeding Habits

Dwergkogelvissen are carnivorous and tend to eat snails in their natural habitat. For aquarium life, feeding them live foods such as daphnia, artemia, or grindalworms works best.

Avoid feeding them flake or pellet food, as these will likely lead to digestion issues that the fish may struggle with.


Dwergkogelvissen are known for their intelligence and inquisitive nature. They are highly active and enjoy exploring their surroundings.

While they can be shy at first, they tend to warm up to their owners over time and may even recognize them.

Breeding Habits

Breeding Dwergkogelvissen can be challenging, however, it is important for responsible pet ownership in order to reduce the number of fish being caught in the wild. To breed them, utilize water changes, Java moss, and mop head aggregates in order to encourage the fish to breed.

Additionally, adding microworms or grindalworms to their diet can increase their chances of successful breeding.


In summary, Dwergkogelvissen are a unique and fascinating species of fish that can make a great addition to any aquarium. While they do require some specific care requirements and can be challenging to breed, they offer a lot of rewards in terms of fun and engaging behavior.

Setting up a successful and harmonious community tank is a major goal for many aquarium hobbyists. The idea is to have a tank filled with different types of fish that can coexist together without any issues.

However, not all fish are suited for this kind of setup. Some species can be very aggressive towards other species, and if they are included in a community tank, they can create chaos, harm, and even kill other inhabitants of the tank.

In this article, we’ll take a look at which fish species you should avoid when setting up a community tank, and which makes the best tankmates for a peaceful coexistence. Not Suitable for Community Aquariums: Aggressive Fish

One of the biggest reasons community aquariums fail is because they contain aggressive fish.

Aggressive fish are a category of species that are known for attacking or harming other tank inhabitants. Some aggressive fish may bully the smaller or weaker species, while others may kill, eat, or nip at the fins of other fish in the tank.

In general, you should avoid adding the following species of fish to your community aquarium:

– Cichlids

– Bettas

– Gouramis

– Barbs

– Angelfish

– Dwarf Crayfish

– Freshwater Pufferfish

Best Tankmates for a Peaceful Coexistence

When it comes to finding the best tankmates for your community aquarium, there are several points to keep in mind. First and foremost, you need to pick species that are non-aggressive and peaceful in nature.

Additionally, it is best to select fish with overlapping food requirements so that everyone in the tank can share their food peacefully. Some species that are ideal for community tanks include:

– Small Tetras (e.g., Neon Tetras, Cardinal Tetras)

– Otocinclus Catfish

– Kuhli’s Loaches

– Guppies

– Harlequin Rasboras

– Cherry Shrimp

– Mystery Snails

Wilde Populatie: The Importance of

Sustainable Breeding

Fish keeping is an amazing hobby, but it can also be harmful to the environment if it’s not done sustainably.

Unfortunately, many species of fish are caught in the wild for the pet trade, which can lead to overfishing and damage to natural habitats. One of the most effective ways to combat this problem is through sustainable breeding.

In this article, we will discuss the importance of sustainable breeding, methods to achieve it, and how it can help protect wild populations.

Declining Wild Population

The wild population of many popular aquarium fish species has decreased by 30-40% in the past five years due to overfishing and habitat loss. This decline poses a significant threat to the survival of these species, as they are being caught in the wild at a rate that the population cannot keep up with.

An example of a fish species that is threatened in the wild is the Clown Loach, which is commonly caught for the aquarium trade.

Sustainable Breeding

One effective solution to this problem is sustainable breeding. Fish breeders can help reduce the demand for wild-caught fish by creating a reliable supply of the same species through sustainable breeding practices.

Sustainable breeding is a process that focuses not only on the health and genetics of the fish population but also on minimizing the negative impact on the environment, such as water use, waste management and energy consumption.

Breeding Methods

One way of focusing on sustainable breeding practices is by breeding more females than males. The females produce eggs, and thus the number of fish in a population can increase rapidly if there are enough females.

Once the females lay their eggs, they are then moved to a seperate tank or container where the eggs will be protected. The breeders then use afzetmoppen/Javamos, outgrowth tanks and various types of small aquatic creatures such as microworms, grindalworms, and artemia as food for the young fish.

In this way, the breeders can raise a healthy and robust population of fish in good condition.

Reduced Wild Catch

Sustainable breeding is also essential to help reduce the number of wild-caught fish. By creating a reliable supply of fish through sustainable breeding practices, pet stores and hobbyists may prefer captive-bred fish over wild-caught fish.

That will eventually reduce the demand and thus minimize the negative impact on the wild population.


In summary, creating a community aquarium that is peaceful requires careful planning and consideration. Avoiding aggressive fish and selecting peaceful species as tankmates is essential for a safe and harmonious environment.

Also, it’s crucial to keep in mind the importance of sustainable breeding, mainly when breeding fish that are threatened in the wild. Implementing breeding practices that conserve the population of these species, can help us maintain biodiversity, and ensure fishkeeping can continue to be a sustainable and enjoyable hobby.
