The Clown Loach, also known as Botia Macracanthus, since this was previously its scientific name, is a fish of the Cobitid or Loach genus.
It is one of the best-known aquarium fish of its kind, perhaps because of its bright and attractive colors, although it is not the only interesting feature of this fish:
It has nocturnal habits, it is quite disturbed by light, although less than other loaches.
It can make clicking sounds, audible even outside the aquarium.
It is a calm and sociable fish, which can live quietly sharing space with other species, it likes the lower part of the aquarium. If this is the fish you are looking for, we are going to see its main characteristics, life habits, what the Clown Loach eats, in short, if you can incorporate it into your aquarium.
Its body is cylindrical, elongated and thick. Its main color is yellow divided by three vertical black stripes. Its pectoral and caudal fins have reddish tones.
In the wild, these fish can measure up to 15.75 inches, but in an aquarium it is quite rare for them to reach that size, and it is common for their growth to slow down or stop when they reach 5.90 inches to 7.87 inches.
Its body is elongated and laterally compressed, finished off with a very thick and strong caudal fin.
The mouth, which opens downwards, has four pairs of barbels.
Another very interesting morphological detail is the presence of an erectile spine under the eyes, which serve as a weapon against predators, and which can hurt us when handling it in the aquarium.
They have a bright yellow-orange color, crossed by three very well defined black bands, the first of which, oblique and less marked, crosses the eye, the central band is almost vertical, while the third band, also oblique, it is oriented in the opposite direction to the first and covers the dorsal fin and goes down to the abdomen.
Distribution and habitat
The Clown Loach is native to the Big Sunda Islands of Borneo and Sumatra.
It is known that there are genetic differences, depending on the island from which they come, and some scholars have suggested that a detailed study be carried out, to determine if they are different species.
Their natural habitat changes depending on the time of year and also depending on their age.
They usually live in the main channels of the rivers, but they go up the smaller channels to spawn, during the wet season of the year, when some areas are flooded.
The young specimens usually remain for several months, in the areas where the Botia Payaso fish reproduces, while the adults return to the main rivers after spawning.
The places that it usually inhabits in its adult state are soft water rivers, with areas of swampy forest, with a large amount of vegetation that causes thick shade.
The bottom contains substrate with large amounts of decomposing vegetation, tree roots, logs… these currents are usually very slow.
Its great distribution makes the aquatic parameters vary a little to maintain them. However, as a general rule, they prefer warm waters around 80.6ºF, slightly acidic to neutral, soft and moderately hard.
Therefore, fish are found in different types of habitat depending on the time of year, and the habitats themselves vary as well; the flow and depth of the water tend to increase considerably during the wet season, for example.
Turbidity and pH also tend to increase during this period as the water temperature drops.
Conditions of the aquarium
Due to their growth and preferring to be in small groups, the recommended aquarium size is 52.80 gals.
The recommended temperature can range between 75.2ºF and 80ºF, with a pH between 5.0 and 8.0, and a water hardness between 50 and 120 mg/L.
The aquarium should have a bottom of sand or fine gravel, with roots and stones that can serve as a refuge.
They are very curious and like to inspect any hole or crack, so care must be taken with the shelters, that they are not too small and that they do not have sharp edges.
As for plants, they like well-planted aquariums, where they can easily find shelter.
Because moderate lighting is recommended, the best plants to introduce are Java Fern, Java Moss, or Anubias.
They require aquariums with little water movement, very well oxygenated and that do not accumulate organic waste.
They belong to the Cobitidae family that includes about a hundred species.
The B. Macracanthas are not friends with very intense lighting, so they will always seek refuge among the vegetation and decorative objects in the lower part of the aquarium.
Placing floating plants will allow us more time to observe these striking fish.
They are very active at dusk and search for food on the substrate with the help of their sensitive barbels, similar to those of Corydoras, which we can locate in their mouths.
We should consider a tank of at least 26 gal to keep Botias.
It must be sufficiently planted and have logs and rocks that offer them hiding places.
The filtration system does not have to be oversized, it will be worth the one adjusted to the Biological load of the aquarium.
In many places it is said that the Clown Loach is omnivorous and indeed, it will eat almost anything, but they are mainly carnivorous fish.
For proper development, growth and to avoid any type of disease, it is advisable to follow a varied diet, which can include quality dry products, live or frozen worms, Tubifex, Artemia, as well as fresh fruits and vegetables.
In the aquarium we can feed the B. macracantha in a simple way.
It accepts all types of food including flake and freeze-dried food, but it is more convenient because it can reach the area where our animals are.
Fast sinking tablets and pellets can be the basis of food.
So that they do not bite the leaves of the plants, it is advisable to offer them regularly pills with a vegetable contribution.
Preferably choose plants with hard leaves. We can distinguish the attack on our plants because we can clearly see the holes they make in the leaves.
It also willingly accepts any type of frozen food, especially red mosquito larvae and homemade porridge.
His habit of vacuuming animal will benefit the maintenance of the substrate by ingesting the remains of food that have been left unconsumed.
Behaviour and Compatibility
Although it is not a particularly aggressive fish, rather calm, it must always be taken into account that the Clown Loach is a fish that acquires a good size and usually has a very active behavior and is less shy than other Cobitids.
For example, fish that typically have ornamental tails, such as guppies, bettas, or some cichlids, can get their fins bitten off.
In general, it is recommended to include with peaceful cyprinids, it can also share space with many catfish.
Their behavior is gregarious, so it is recommended to keep groups of no less than 5 or 6 individuals, in which quite complex social hierarchies are formed.
They take several years to reach sexual maturity and in the aquarium, they do not reach their full development as adults.
In nature, these fish reproduce by migrating from their usual place, reaching small river channels and flood plains.
However, in the aquarium these conditions cannot be reproduced and therefore, they are not fish that reproduce in a community aquarium.
All the Botia Payaso that we find for sale are usually species taken from their natural environment, so there is a certain risk of depopulation.
Botia fish care
We must bear in mind that although in the aquarium they will never reach sizes of 11.80 inches, which is what they can develop, they are a species of certain dimensions, so we must plan their maintenance based on their adult size and not the moment of their birth. purchase.
The dimensions of the aquarium mark the final size of our specimens.
In captivity they do not usually exceed sizes of 4.70-5.90 inches.
There are originally in northern Borneo some populations of giant Botia macracantha that can reach sizes in the aquarium of up to 9.84 inches.
Its tonality is more matte than the small Clown Boots.
Buying a group is also a considerable investment given that if properly cared for the life expectancy is greater than twenty years.
The most important thing for these botias is that they always have clean and well-oxygenated water.
Frequent water changes of about 30% a week are needed.
With your weekly water change make sure to vacuum the gravel to remove all excess food and debris.
Be sure not to remove biofilm from rocks, decorations, or aquarium glass.
An electric gravel cleaner usually does a great job of keeping the bottom of the aquarium clean.
Be careful when cleaning the aquarium so as not to be pricked by the Clown Loach’s spines.
Water changes: Weekly.
This Clown Loach can be hardy in the right conditions.
They are not recommended for beginners due to their need for pristine water and small body scales.
Reduced scales make them more prone to disease and highly sensitive to medications used to treat them.
Experience treating scaleless fish is very important in order to give your Clown Loach a long and healthy life.
Do not attempt to introduce these fish into biologically immature aquariums.
Be sure to check compatibility with other tank mates as Clown Loachfish get stressed quite easily.
Because the Clown Loach is so susceptible to ich, be careful when introducing new fish to your aquarium.
This botia will often lie on its back or side, this is normal.
Resistance in the aquarium: Moderately resistant
Aquarist Experience Level: Intermediate
Botia fish health
When choosing our Boots we must pay special attention to the ventral area.
Those animals with a sunken belly should be discarded as it is a symptom of the presence of parasites.
Poor coloration in the trade should not be a reason for rejection because they tend to fade when stressed.
We must be careful in transport because the thorns mentioned above can puncture the bag.
It is common that they can bury themselves in the substrate, so we should not worry too much if we do not see our animals recently incorporated into the aquarium.
It is not common, but in times of stress it can jump out of the aquarium, which is why it is more advisable to install facilities with a lid.
They are not delicate fish or sensitive to diseases, although they can develop the common ones in all community aquariums.
There are two exceptions with respect to diseases that we must take into account: They are sensitive to white spot (Ichthyophthirius multifilis), which can be triggered by any stress situation or drop in temperature, and to velvet disease (Oodinium). They tend to respond well to treatments and usually end up eradicating the disease without treatment if the balance in the aquarium is restored. Amoxicillin for fish ampicillin for fish.
It is very good practice to leave the aquarium without light for 24 hours after the introduction of our new animals so that they calm down and reduce stress so that we will not reduce their natural defenses.
