Asian Stone Catfish Stats: A Quick glance

What sets the Asian stone catfish apart from other species of the same size is their long pectoral spines which they use to lodge into nooks in the water. The dwarf anchor catfish truly lives up to its name as it resembles an anchor when viewed from the top.

These Asian freshwater fish can easily be kept in a community tank due to their peaceful nature.

However, before you consider bringing them home, check out some important stats pertaining to hara jerdoni care right here:

Asian Stone Catfish: Optimal Care Requirements

As mentioned above, the Asian stone catfish size is merely 3 to 5 inches, making it an ideal choice for nano fish tanks holding 3 gallons of water.

Besides, the species does not require a large room to swim around as the fish are mostly inactive due to being nocturnal in nature. Regardless, there are certain arrangements that you need to tend to before adding a delicate moth catfish to your home aquarium.

These include the following:

– Water Conditions

Ideally, a 10 gallon fish tank is sufficient enough to house a small school of hara jerdoni as they are not active swimmers. However, despite the tank size being small, it is imperative to maintain certain water conditions for the asian stone catfish care. For instance, the aquarium temperature should be set between 18°-24° C with a pH level of 5.6–7.6, and medium hardness.

Furthermore, the moth catfish can only survive in captivity if the water is well filtered, adequately oxygenated, and calm. A drop in the oxygen level or increased nitrates can be fatal for this species, apparently causing them to shed their skin.

Since the Asian freshwater fish is a bottom dweller, it is prone to bacterial and fungal infection. Hence, to promote their longevity and overall health, it is important to maintain the hygiene level in the aquarium by vacuuming the substrate regularly. However, take additional care when you vacuum as the critters often bury themselves in the sandy bottom.

– Aquarium Decoration

The moth catfish thrives in slow moving water bodies with sandy bottoms. It is a nocturnal species that sneaks out from its refuge in daylight only when it feels safe. It is, therefore, vital to take care of creating a suitable environment for it inside the aquarium.

This can be done by ensuring the following:

  • Sandy Substrate
  • Light Gravel or a few small stones
  • Lush plantation of Java moss, fern and baby grass
  • Dried oak and beech leaves to replicate their natural habitat
  • Driftwood, rock structures and bamboo pieces
  • Dim lighting unit or surface plants

Primarily, the only thing that this nocturnal fish requires to find comfort in captivity is ample hiding places. Therefore, it’s essential to decorate the fish tank aptly in addition to maintaining ideal water quality. Doing so will perfectly simulate the natural habitat of hara jerdoni.

Asian Stone Catfish Tank Mates: The Ideal Companions

As a peaceful shoaling fish, the moth catfish is well suited for community tanks. In fact, you can also add it in a biotope setup with similar tiny species, or more of its own kind, as it prefers the comfort of hanging around in a group.

However, hara jerdoni care also calls for ensuring that none of its tank mates are active bottom dwelling species. This will otherwise almost always leave them out-competed for food.

The nano fish is compatible with several other fish and invertebrates that thrive in similar water parameters and are approximately its own size.

The most compatible tank mates for this gregarious species include the following:

  • Celestial Pearl Danios
  • Golden Dwarf Barbs
  • Scarlet Badis
  • False Harlequin Rasboras
  • Mosquito Rasboras
  • Farlowellas
  • Other peaceful Indian fish
  • Cloud Minnows
  • Adult Dwarf Shrimp

It is advisable to make dwarf anchor catfish the only bottom dweller of your tank to prevent harassment from the other tank mates.

Asian Stone Catfish Breeding: How to Proceed?

While some aspiring aquarists may find Asian Freshwater fish breeding difficult to handle, there are others who consider it fairly easy. The species has been bred in captivity, but taking care of the egg layer can be a tricky task.

Take a look at the enlisted steps for a better understanding of how to proceed with Asian stone catfish breeding:

  1. Prepare a small aquarium for breeding by decorating it with spawning mop, Java moss or baby grass.
  2. Now, put in 4 to 5 adult hara jerdoni for mating. The females have a fuller body with the pectoral fin curving inward while males possess longer fins and barbels. An ideal ratio would be 2 males for 3 females.
  3. Condition the potential mates by feeding them live food for a few days, before spawning.
  4. Ensure a 30% water change every 4 to 5 days to reduce nitrogenous waste in the breeding tank. You may also need to install a sponge filter to keep the water well oxygenated, clean, and stagnant.
  5. If rightly done, Asian stone catfish eggs are likely to be found in the java moss or baby grass soon after spawning.
  6. Although the species is not known to eat its own fry, it is best to remove the adults from the breeding tank. This will allow you to provide special care for rearing the delicate newborns.

Nevertheless, breeding these oviparous fish does not require any special equipment or instruments. All you require is a spare tank and the basic knowledge of the habits and anatomy of the species. The water quality, temperature, lighting, and plants in the breeding tank are the most crucial factors in hara jerdoni care and breeding.

Asian Stone Catfish Diet: What do They Eat?

By now, we know how reclusive the dwarf anchor catfish is. So much that you will probably not even notice it in the aquarium during the day. The nocturnal critter usually comes out of hiding at night in search of food.

Furthermore, like many other freshwater species, Asian stone catfish diet consists mainly of live food as well as frozen varieties like daphnia, cyclops, brine shrimp, and bloodworms. The omnivore is also likely to accept dried pellets and algae wafers readily after settling down in an aquarium setting.

All in all, hara jerdoni are not fussy eaters and can often be seen picking through the substrate and leaf litter in the tank for leftover food. It is advisable to feed them only once or twice a day to prevent overeating.

Conclusion

Stone catfish lifespan is not more than 5 years. Hence, to ensure its longevity over the years, it is essential for fish owners to provide the dwarf catfish with adequate care. We have made sure to cover all aspects of rearing Asian stone catfish in captivity.

Here’s a recap of the article:

  • Hara jerdoni is a miniature nocturnal species that hails from the streams and ponds of Asian countries, mainly India and Bangladesh.
  • The dwarf anchor catfish size, and the fact that they are not active swimmers, makes them a great for nano aquariums.
  • This Asian freshwater fish care primarily revolves around specific water conditions as well as appropriate aquarium décor.
  • The species thrives well in well filtered water with sufficient oxygen levels and a temperature ranging between 18°-24° C. The medium hard water environment should have a pH level of 5.6-7.6.
  • As the fish is a shy nocturnal creature, it is vital for aquarists to provide them with a lot of good hiding places in the tank where they can seek shelter through the day.
  • Being peaceful and gregarious fish, hara jerdoni is compatible with many other small fish and invertebrates. Some excellent tank mates include golden dwarf barbs, rasboras, celestial pearl danios, cloud minnows, scarlet badis, and dwarf shrimp.
  • Avoid adding active bottom dwellers in the same tank as they are likely to harass the Asian stone catfish and outcompete it for food.
  • Dwarf anchor fish are omnivorous and you can easily create a separate tank with spawning mop for breeding them conveniently.
  • The moth catfish diet consists majorly of live and meaty frozen food like bloodworms, brine shrimp and cyclops. Besides, It may or may not accept dry pellets initially.
  • Feed them only twice a day, after the lights are out so that they sneak out of their hiding place to grab a bite.

On the whole, even though their presence is hardly felt in the tank, Asian stone catfish are undoubtedly a unique addition to any aquarium. They are fascinating in their own way. But taking care of the species can appear as somewhat tricky due to their environmental and dietary needs.

Just make sure to add in a few tank mates of their own kind, and the shy fish will surprise you with its social skills!
