Garra Rufa, The Boisterous Algae Eater Fish That Offer Many Beneficials

The Garra rufa fish is an unfamiliar algae-eater that many hobbyists add to their planted tank setup. Some people might never have seen them settle in home aquaria due to their use in fish therapy at spa industries.

Good to know, Garra rufa is excellent for combating algae blooms inside tanks. Additionally, these fish can treat skin diseases in a manner similar to leeches, including psoriasis, eczema, dermatitis, and heavy legs, as well as aid in wound healing.

Israel is the biggest manufacturer that commercially supplies the Garra rufa to the aquarium and spa trades. Turkey also contributes to this effort, although in a smaller capacity, as this country protects them legally from being caught in the wild, thereby preventing overharvesting.

This article is suitable for anyone seeking information about Garra rufa or those starting to keep them, so please continue reading.

General Information

Garra rufa (red garra) is an algae-eating fish species under the family of Cyprinidae that originates from various freshwater habitats in the subtropical territories of Western Asia.

There are three alternative names (common names) for describing this fish in the trade: doctor fish, kangal fish, and nibble fish.

Their scientific name consists of two words, ‘Garra,’ which means vernacular gangetic name for a particular species of “sand-digger,” which is applied by Francis Buchanan-Hamilton as a generic name for a type of cyprinid, bottom-dwellers that are without affinity to another genus.

And another word, ‘rufa,’ is from Latin’ rufus,’ which means ‘red, reddish,’ which refers to the reddish pigmentation on the head of some individuals.

These fish also have some synonym names, including Discognathus crenulatus Heckel 1846–49; Discognathus lamta non-Hamilton 1822; Discognathus obtusus Heckel 1843; Discognathus rufus Heckel 1843; Garra rufa crenulata Heckel 1844; Garra rufa gymnothorax Berg, 1949.

The doctor fish have been introduced into spa treatments since the early 21st century due to their ability to alleviate the symptoms of psoriasis, where they eat the stratum corneum, the top layer of the skin, of patients with this disease.

However, the use of doctor fish for spa treatments among the broader public remains controversial due to concerns about their effectiveness and validity.

Distribution And Habitat

The Garra rufa algae eater is distributed in several regions in the Mediterranean and the Middle East, including Turkey, Iran, Iraq, and Syria.

Some main water streams where they are found include Kızıl, Seyhan, Ceyhan, Orontes/Asi, smaller Turkish water systems, Queiq/Qweik, the Jordan river drainage in Jordan and Israel (except the Southern Dead Sea basin, which is substituted by their congener Garra ghorensis), Tigris-Euphrates, Kor, and Mond river basins.

They also occupy most of the coastal watersheds in Syria and the endorheic lake system of Maharlu in southwestern Iran. The locality of these species is Aleppo, Syria.

Mostly, they live in fast-flowing streams in headwaters and tributaries; some colonize several larger, lowland river channels. They also inhabit other water bodies, such as canals, ponds, lakes, and artificial reservoirs.

In some cases, these fish inhabit ephemeral habitats that become partly desiccated at particular times of the year. Garra rufa algae eaters are often found to survive in water zones heavily influenced by human activities, such as polluted canals.

Nibble fish tend to avoid still-water systems. Their favorite habitat in the wild is streams that contain clear, highly oxygenated water, which is associated with sunlight that promotes the development of a rich, submerged biofilm. 

Appearance Of Garra Rufa Algae Eater

Sometimes, in the same country of origin of these fish, they likely consist of different populations of G. Rufa, which tend to vary in appearance, and a chance of hybridization with another species cannot be ruled out either.

Nevertheless, doctor fish exhibit several similarities throughout the vast majority of their range.

Red garra’s fins and bodies vary in coloration. However, most of them have iridescent or dark blue patches at the upper edge of the opercle and another one on the caudal peduncle. Younger individuals can be distinguished by the prominent bluish color spots at the caudal peduncle.

On the basis of their central dorsal-fin rays, a series of dark markings usually appears. It often occurs in many specimens that the end of their upper caudal fin lobe is black.

That said, the population of Garra rufa from Iran and Iraq has some different characteristics as follows: they have two pairs of barbels; most of them possess 8 (87.1% for 534 specimens, range 6 – 8) branched dorsal-fin rays; and they have an adhesive disc on the lower head surface that grows well with a free anterior margin.

Generally, these small freshwater fish species can reach a total length of up to 5.5 inches (14 cm). However, the captivity form rarely exceeds 3.6 inches (9 cm), while the wild type may grow larger, reaching around 9.5 inches (24 cm).

Even though they are not developed too large, the nibble fish known can live longer, more than seven years, under better maintenance.

Behavior And Temperament

Garra rufa algae-eater fish are relatively peaceful. They can be kept with other species that require similar environmental conditions to thrive.

Unfortunately, they can be intolerant of conspecifics in a nano aquarium. However, aggression towards other fish is more pronounced in larger spaces or their natural habitat.

Doctor fish tend to become more aggressive when kept with other similarly shaped fish, especially if they are kept singly. We suggested buying 4-6 fish or more and ensuring there is enough space.

Grouping like that will create a prominent pecking order among themselves; it would reduce the temperamental intensity between the members.

The reason they are interesting is that they are very active and lively, always on the move. Garra Rufa spent almost a whole day looking for food; their pair of barbels was helpful in this activity. Occasionally, they also hide near stones or wood when stressed or relaxed.

These tropical fish are not timid species; without feeling fear of any strange object, they would observe and occasionally nibble it. If that contains some snacks that these fish can eat, Garra rufa will continue to nip at it. This can happen to customers’ hands or feet when they are fully submerged in the pond during the spa service.

They can be more boisterous during feeding time; then, the food disappears in a while.

Sexual Dimorphism

Like most common freshwater fish, the females of Garra rufa are usually distinguished by their thicker bodies. On the contrary, mature males are smaller, thinner, and develop extensive tuberculated patches on their snout and head. While the genital papilla shape is visible during the spawning period, the male will show bridal buds on the top of their mouth and cheeks, and have longer pectoral fins.

Reproduction

Garra rufa are very productive fish. They tend to reproduce continually for a slightly longer period. In the wild, spawning typically occurs between April and November, coinciding with the warm and rainy seasons.

Before starting to breed these fish, make sure to select the high-quality fish parents that can be diagnosed as follows:

• Having a good color and markings
• Choose healthy, mature doctor fish.
• Select only pairs from the same species to prevent hybridization.

Conditioning the parent fish is crucial to achieving the goal of producing the best offspring. This process feeds the Garra rufa algae eater with a variety of healthy food as well as live food.

The breeders usually use brine shrimp, bloodworm, insect larvae, Moina, and other related meal types to put them in the best condition when they spawn.

Should you know, the red garras are the egg-scattered type, where they lay their adhesive or non-adhesive eggs into substrate, plants, and decorations, or they even leave them to float to the surface. Besides, they also do not look after their eggs, and they can even be consumed by them.

Provide a separate breeding tank necessary to increase the reproduction rate. Use a 5- to 10-gallon tank size, install an air pump, and add a sponge filter to create slow-moving water. The tank should also be equipped with a heater, as well as plenty of live aquatic or artificial plants and mops.

To avoid predation by their parents, the substrate should consist of two layers of pebbles or marbles or a fine nylon net above the aquarium floor.

Once the eggs are released, they will fall through the pebbles or net that the mature fish can not reach.

Raise the water temperature, decrease the tank water to half of the tank, and the ph level should be between 7-7.5.

Spawning usually occurs in the morning and produces 200–500 eggs, which measure only 1.5–1.88 mm and are transparent. After mating, the parents should be moved to a separate tank.

The incubation period takes between 24 – 30 hours, depending on the temperature. Three sides of the breeding aquarium should be covered with black paper, as light can promote the growth of fungus and cause discomfort to the fry.

After the eggs hatch, the fry will spend their yolk sacs for around 72 hours before they can swim freely.

When it’s gone, the hungry fry will start to find food; they can be fed with infusoria, boiled egg yolk, or green water. After one week, they can accept larger food such as daphnia, artemia nauplii, or white worms.

At the age of fifteen days, the Garra rufa babies can eat dried food that is customized to their size or other larger live food like brine shrimps, larvae insects, and chopped tubifex worms.

Perform 2 or 3 feeding sessions a day. To avoid cannibalism among the fry, sort them by their size periodically.

A daily water change of 25-50% is required to keep the fry healthy. The new water must have the same characteristics as the water taken out. It is because the fry is sensitive to sudden changes in water chemistry. Do not forget to take out the sick and deformed fish.

Under favorable water conditions, a proper feeding diet, and regular water changes, the fry should grow well and faster.

Feeding And Diet

These species are easy to feed because they are omnivorous. In the natural environment, their primary diet commonly consists of various algae types (Cladophora, Spirogyra, Rhizoclonium, Staghorn, Oedogonium, GDA, and GSA), detritus, and tiny animals such as zooplankton and arthropods.

In the home aquarium, offer them a conventional food type such as spirulina-based sinking pellets, vegetables (zucchini, spinach, cucumber, peas), and fresh fruits (melon). Completing their nutrition with live food encourages coloration, including artemia, shrimp meats, tubifex, or bloodworms.

Tank Requirements And Aquarium Setup

At the very least, you should provide a 30-gallon tank to accommodate six individuals. This will give them sufficient space to explore every corner of the tank. You can add some similarly sized tankmates inside.

A perfect setup for them should resemble a river environment, as it is their natural habitat. Commonly, the substrate consists of various-sized rocks, fine gravels, sands, and maybe some boulders. Ensure the gravel or stones are not sharp, as their barbs are fragile.

Create a bare space for them to search the ground. Arrange the rocks in a way that allows for the creation of hiding areas. In nature, they prefer to hide under stones or vegetation to rest.

Completing the decorations with driftwood or branches, as well as other kinds of stuff like pipes, vases, or anything you want. It offers many shade areas inside the aquarium.

Apply a filtration system to maintain the water consistently clean and well-oxygenated. We are advised to use a filter that can turn over the water more than ten times per hour.

Equipped the aquarium with other tools that can support the water cycle, such as powerheads and an aerator, to enhance the flow and oxygenation if necessary. These fish do not require a heater, except to stimulate breeding.

There are no specific rules for light intensity, but strong lighting can promote the growth of biofilm at the surface, which is particularly beneficial for Garra Rufa. It can also drive some algae species to thrive.

Adding hardy aquatic plants, such as anubias and cryptocoryne, offers additional benefits, including enhanced oxygen levels and a magnificent display. Floating live plants, such as salvinia natans, can be added if required. Ensure they are cleaned up using parasite killers to prevent the introduction of harmful animals, such as scuds and ramshorn snails.

Cover the planted aquarium with the tank lid. They can literally jump out. Below is a formula for the water parameter that the Garra rufa fish prefer:

• Temperature Level: 14 – 20 °C
• pH Level: 6.0 – 8.0
• Water Hardness: 18 – 268 ppm

Maintenance And Care

They should not be added to the immature aquascape tank setup since they require stable water conditions and are developed with biofilm.

Performing a regular water change of approximately 30% every week is necessary to maintain the water in optimal condition. You can add biofilm powder to boost its growth, which will make the Garra rufa happier.

You can leave their aquascaping tank incompletely clean. It triggers the algae to become established. However, organic waste such as fish feces, decomposed plant matter, and dead creatures should be removed. This leads to many problems in your fish tank and is preferred by some aquarium parasites, including planaria flatworm, hydra, and detritus worm.

To obtain algae stocks, you can cultivate them in a separate tank. Place some rocks inside, provide bright lighting, or position this tank outside. Leave the captivity tank until algae are spread on the surface of the rock. Enter the algae rocks into the Garra rufa tank, substituting the stones from the fish tank with them. Then, perform a cycle to encourage continuous algae growth.

Feed your Garra rufa fish 2 or 3 times a day. Dividing their diet into small portions several times is preferable to giving it in high amounts at one time.

Tankmates Of Garra Rufa Algae Eater

The compatible tank mates should have characteristics similar to those of the Garra rufa. Some small freshwater fish that we recommend are tetra species, mollies, rainbowfish, danios, guppies, dwarf gouramis, licorice gouramis, and other related fish types.

The slower-moving fish, such as discus and angelfish, are not suitable as tankmates. They may outcompete during feeding and might be bothered by their slower swimming speed.

Never try to put in some larger, territorial, and aggressive fish, such as Oscars or Flowerhorns. They would intimidate the red garra, causing these fish to become very stressed.

Adding zebra nerite snails or other similar mollusk species is permitted on the condition that the aquarium must be large enough to accommodate them. Do not force them to live in the small tanks.

Clearly, your tank should have sufficient spaces for them to avoid conflict between aquarium members.

Potential Diseases

Like most freshwater fish, they can be affected by common diseases, including white spots, fin rot, dropsy, fungal infections, and bacterial infections. However, no species’ illness is known until this article was written.

Availability

They tend to find local breeders and online trades rather than in local fish stores. Because the Garra rufa is more commonly used in the spa industry, most aquarium shops prefer to sell other famous algae eaters, such as the Siamese algae eater or the Chinese algae eater.

The standard doctor fish usually costs about $3-$5 for an adult and healthy individual. However, some sellers may offer a lower price for purchasing in bulk.

Are Garra Rufa Fish Suitable For Newbies?

Yes, they are suitable for beginners because they are easy to care for and do not require many special conditions to thrive in the aquarium. Despite that, an inexperienced aquarist who tries breeding them straightforwardly is not advised. They should learn a great deal of information and gain sufficient experience with these fish before attempting to do so. Of course, it may take a considerable amount of time.
