Unlock the Secrets of Gourami Fish Diet: Ultimate Feeding Guide for Vibrant Health!

Looking for a captivating addition to your freshwater aquarium? Gourami fish, with their vibrant colors, unique personalities, and relatively low-maintenance care, are a popular choice for both beginner and experienced aquarists. Gouramis are not only captivating to observe but also relatively easy to care for, making them a popular choice among aquarists. This comprehensive guide dives into the specifics of gourami diets and feeding habits to ensure the health, happiness, and longevity of these fascinating fish.

Understanding Gourami Species

Gouramis come in various species, each with unique characteristics. Some common types include:

Dwarf Gourami (Trichogaster lalius): Small, colorful, and ideal for community tanks. The regular variety is already stunning with its shiny, light blue body and red, vertical stripes. Growing up to 3 inches (8 cm) long, it is one of the smaller gouramis available in the aquarium hobby and is part of the same family as betta fish and paradise fish.
Pearl Gourami: Known for its elegant appearance and peaceful nature.
Honey Gourami: Very small with a brilliant golden color.
Kissing Gourami: Easily identified by their "kissing" behavior. Kissing gouramis get to be quite large and will need a 55-gallon tank or larger when full size.
Three-Spot Gourami: Hardy and adaptable, making them ideal for beginners. Remember that blue, three spot, opaline, gold and lavender gouramis are all the same fish - they have just been bred for different colors!
Giant Gourami (Osphronemus goramy): The largest of the gourami family, growing up to two feet long in the wild. Osphronemus goramy, the "True" or Giant gourami, can grow to 24" and adults require an aquarium of 250 gallons or larger.

Natural Habitat and Dietary Adaptations

Gouramis originate from Southeast Asia, commonly found in countries such as Thailand, Vietnam, Cambodia, and Indonesia. Gouramis are found throughout eastern and southern Asia, from Pakistan through Thailand, Vietnam, the Malaysian Archipelago, China and as far north and east as Korea and Japan. These regions have dense vegetation and slow-moving waters, making Gouramis well-suited to heavily planted tanks. In their natural habitat, Gourami fish inhabit ponds, lakes, and slow rivers with warm, slightly acidic water. This environment has shaped their dietary habits, making them omnivores that consume a variety of foods.

Gouramis are a group of fish in the families Osphronemidae, Helostomatidae and Anabantidae. They have a labyrinth organ that acts sort of like a lung, which allows them to breathe air at the surface. In nature this adaptation enables them to live in shallow, stagnant, oxygen-poor water.

Tank Setup and Environmental Considerations

Gourami require a well-maintained freshwater tank with plenty of plants and hiding spots. Here are the recommended conditions for maintaining Gouramis:

Tank Size: Minimum tank size is 20 gallons, and a bigger tank should be used in larger species. Sparkling, croaking, honey and dwarf gouramis can be kept in tanks as small as 10 gallons, while a 30-gallon aquarium or larger is recommended for pearl, blue, gold, opaline and moonlight gouramis, as well as paradise fish. To aid oxygen availability in the fish tank, choose a long tank that has a correspondingly large surface area, rather than a tall, narrow one.
Temperature: Maintain a water temperature of 72-82°F (22-28°C). The gourami Osphronemus goramy is a tropical fish that needs a water temperature of between 68.0° to 86.0° Fahrenheit. If the aquarium is kept in rooms below 75°, use an Aqueon Aquarium Heater to maintain the correct temperature.
pH Level: Keep the pH level between 6.0-7.5. Many gouramis are found in soft, acidic water in the wild, however the majority of aquarium species sold today are raised commercially in water that has a higher pH and alkalinity than their native environments, so they are very adaptable. pH should be between 6.8 and 7.8.
Filtration: A moderate filtration level with gentle flow is ideal. Maintain good filtration and change 10% of the water weekly or 25% every 2 weeks using an Aqueon Aquarium Water Changer or Siphon Vacuum Gravel Cleaner. Do not forget to treat tap water with Aqueon Water Conditioner before refilling your tank.
Aquatic plants: Include live plants like Java fern, Vallisneria, and Anubias. For a pop of color, red tiger lotus is a stunning addition to your Gourami tank. Its broad, red leaves float near the surface, providing shade and cover, which helps reduce stress for Gouramis. This grass-like plant can form a dense carpet along the bottom of your tank, creating a natural feel and offering smaller Gourami species additional hiding places. Aponogetons are great centerpiece plants, with their wavy, translucent leaves reaching up toward the surface.
Lighting: Moderate lighting is sufficient for Gouramis.

Gourami Diet: What to Feed Your Fish

Gouramis are omnivores and enjoy a varied diet that includes both protein and plant matter. For the best health and color of your gourami, provide them a varied, omnivorous diet of prepared, gel, frozen, and live foods. Here's a breakdown of suitable food options:

Flake or Pellet Food: A staple diet providing necessary nutrients. Most gouramis are omnivorous and will thrive on Aqueon Tropical Flakes, Color Flakes, Tropical Granules and Shrimp Pellets.
Live and Frozen Foods: Supplement their diet with bloodworms, daphnia, brine shrimp, and other small invertebrates. Frozen and live foods can also be fed as treats or to help induce spawning.
Vegetable Matter: Include boiled potatoes and other vegetables in their diet. Kissing gouramis are more herbivorous and should be fed Aqueon Spirulina Flakes and Algae Rounds.
They enjoy eating fish flakes, floating betta pellets, community pellets, bloodworms, daphnia, brine shrimp, and more.

For best results, rotate their diet daily and feed only what they can consume in under 2 minutes, once or twice a day. Overfeeding can lead to poor water quality and health issues, so it is essential to monitor their feeding habits.

Feeding Habits and Behavior

Gouramis are often found to be curious and playfully interactive. They are curious and active swimmers, frequently exploring the tank. Anabantoids usually hang out in the top half of the aquarium, but we find that dwarf gouramis swim at all levels and will go after both sinking and floating foods. They are eager eaters that may try to chase away other fish and eat the lion’s share of the food, so watch out for slower species getting outcompeted during mealtimes. Some even display interesting behaviors to observers, like the Kissing Gouramis. Generally, the territorial behavior is associated with the males, mainly before breeding time, so it’s important to monitor tank dynamics.

Tank Mates and Compatibility

Gouramis are generally non-aggressive, but they might fight with similar species. Male gouramis have a tendency to be aggressive towards each other, so they should typically be kept individually. Female gouramis usually tolerate each other well. Mixing different species or color varieties of gouramis should only be done in larger, well decorated tanks. Gouramis are slow moving and are best kept with similar sized fish that are not fin nippers or too active.

Some good tank mates are tetras, rasboras, and corydoras. Larger tetras, livebearers other than fancy guppies, peaceful barbs, most danios and angelfish, can all be good choices. These nocturnal, snake-like bottom dwellers are peaceful and shy, making them perfect companions for Gouramis. Small and peaceful, these algae-eating fish are excellent at keeping the tank clean. Another bottom-dwelling species, Pygmy Corydoras are small, gentle freshwater fish that thrive in groups. These livebearers come in a variety of vibrant colors and are hardy, peaceful fish. Known for their fiery orange color, Ember Tetras are small, peaceful, and schooling fish. These dwarf cichlids are generally peaceful and coexist well with Gouramis. When keeping multiple Dwarf Gouramis, it is best to have more females than males, as males can become territorial and occasionally display aggressive behavior towards each other.

It is not recommended as both species can be territorial, especially males. Gouramis may eat smaller freshwater shrimp, such as baby shrimp.

Breeding Gourami

Breeding Gourami can be a rewarding experience. Here are some key points to consider:

Bubble Nest Builders: Male Gourami build bubble nests to protect eggs. After building a suitable nest at the surface, the male courts the female and a spawning ritual begins.
Water Conditions: Slightly warmer water encourages spawning. Set up a 10-gallon breeding tank with shallow water between 6-8 inches (15-20 cm) deep and warmer temperatures around 80-82°F (27-28°C). Use a sponge filter with gentle flow, and add floating plants (like floating water sprite) to reduce the surface agitation and give the male a foundation to build his bubble nest.
Separate Breeding Tank: A separate tank ensures better survival rates for fry. A separate breeding tank with a capacity of at least 40 liters (10.57 gallons) equipped with an air-driven sponge filter to keep the water flow gentle. Begin by introducing the female into the breeding tank and conditioning her with live and frozen foods until she becomes plump with eggs. Once she is ready, introduce the male. The male will begin constructing a bubble nest at the water's surface. The female will nudge the male towards the nest, initiating the spawning process. During spawning, the pair will intertwine, and the male will fertilize the eggs.
Male and Female Interaction: Introduce a healthy pair of Gouramis into the breeding tank. As eggs are laid, the male retrieves them and deposits them in the nest, which he guards until they hatch. The eggs are extremely light in weight and float to the surface. The male collects the eggs in his mouth and places them carefully into his nest. The eggs usually hatch very quickly after only about 40 hours.
Post-Spawning Care: Remove the female after spawning, as the male will guard the nest. Once the pair are done mating, remove the female because the male will relentlessly chase her away as he guards the nest. The male will protect the fry for a few days until they hatch and are freely swimming. At that point, remove the male so he will not predate on his own offspring. Offer the baby fish tiny foods such as infusoria, powdered fry food, and vinegar eels for the first couple of weeks.

Common Health Issues and Prevention

Like any fish, Gourami can be prone to certain health problems, including bacterial infections, constipation, and Hole in the Head disease. Watch for common illnesses such as fin rot and ich. All these problems are usually caused by poor water conditions or incorrect feeding. So, all new fish should be quarantined for two weeks before introducing them to your display tank.
