Aquascape: The Pearlscale Cichlid (Herichthys carpintis) thrives in aquariums with plenty of open swimming space, but it also enjoys having hiding spots. Use rocks and driftwood to create caves and territories. A planted aquarium can also work well, as long as the plants are hardy and can withstand the cichlid's digging tendencies.
Substrate: A fine to medium-gravel substrate is ideal for Herichthys carpintis, as it allows for natural behavior like digging and burrowing. Avoid sharp substrates to prevent injury to their delicate barbels.
Disease Prevention: Keeping the aquarium clean and maintaining stable water conditions is key to preventing common cichlid diseases, such as ich or fin rot. Quarantine new fish before introducing them to avoid introducing parasites. Regular water changes, proper filtration, and monitoring for signs of stress (which can make fish more susceptible to disease) are essential.
Filtration: As an active and somewhat messy fish, Herichthys carpintis benefits from strong filtration to maintain water quality. A good-quality filter that can handle their bioload is crucial, with the ability to turn the tank water at least 4-5 times per hour.
Lighting: Moderate lighting works best for the Pearlscale Cichlid. While they don’t need intense light, a light that helps highlight their vibrant coloration and creates a natural day-night cycle is important. Avoid overly bright lighting as it can stress them out.
Water Flow: While Herichthys carpintis prefers a moderate water flow, they can adapt to slightly stronger currents. Just be sure there are areas in the tank where the water flow is gentler, allowing them to rest.
Hardiness: The Pearlscale Cichlid is a hardy species, capable of tolerating a range of water conditions as long as the water is kept clean. They are relatively resilient to changes in water parameters, but sudden shifts should still be avoided.
Acclimation: Acclimate your Pearlscale Cichlid slowly when introducing it to a new tank. Drip acclimation or adding small amounts of tank water to the bag over the course of an hour or two is ideal. This gradual introduction helps prevent stress and shock.
Expected Lifespan: With proper care, Herichthys carpintis can live anywhere from 10 to 15 years, though some can live even longer if their tank is well-maintained and they remain healthy.
Special Requirements: While relatively low-maintenance, Herichthys carpintis do need consistent water parameters—particularly stable pH (around 7.0–8.0) and soft to moderately hard water. They also prefer temperatures in the range of 75–82°F (24–28°C). Keep in mind they can be territorial, so they may not be the best choice for community tanks with smaller or more
Temperament and Behavior
Behavior: The Pearlscale Cichlid (Herichthys carpintis) is known for its territorial nature, especially when it is breeding or establishing dominance. While they are generally peaceful when kept in a large enough tank with appropriate tankmates, they can show aggression if they feel their space is being invaded. They are also quite active swimmers, moving through the tank with purpose.
Breeding: Herichthys carpintis are egg layers that exhibit typical cichlid behavior during breeding. They form pairs, and the female lays eggs on a flat surface, which are then fertilized by the male. Both parents typically protect the eggs and fry. The breeding process can lead to increased aggression, as the parents guard their territory and offspring. It’s best to provide them with a separate breeding tank to reduce stress on other inhabitants.
Aggression: While the Pearlscale Cichlid isn’t the most aggressive of cichlids, they can display territorial aggression, especially during breeding seasons. They will defend their chosen area fiercely from other fish, including tankmates. It's crucial to provide plenty of space in the aquarium to prevent excessive aggression.
Tankmates Compatibility: Herichthys carpintis generally does well with other medium to large-sized fish that are also semi-aggressive. They may not do well with smaller, more peaceful species, which can be harassed or outcompeted for food. Suitable tankmates include larger cichlids, robust catfish, and certain types of barbs or tetras, though care should be taken to avoid overly timid or slow-moving species.
Activity Level: These cichlids are moderately active swimmers, often patrolling their territory and exploring their environment. While they enjoy some space to roam, they are not constantly in motion and do take breaks to rest in their hiding spots.
Schooling or Shoaling Behavior: Herichthys carpintis are not a schooling species. They are territorial and prefer to establish a home range. However, they can be kept in groups of several individuals if the tank is large enough, though it is important to have enough space to reduce territorial conflicts.
Plant Compatibility: Pearlscale Cichlids can be a bit rough on plants, especially if they start digging and rearranging their environment. Hardy plants, such as Amazon swords, anubias, or java ferns, are better suited for tanks with Herichthys carpintis. Plants in the substrate may be uprooted or damaged by their digging, so it’s important to either secure plants with rocks or place them in pots to protect their roots.

Diet and Nutrition
Dry Foods: Herichthys carpintis will readily accept high-quality dry foods, such as pellets or flakes designed for cichlids. A varied dry food diet will help meet their nutritional needs. Look for options with high protein content, especially during their growth and breeding phases. Ensure the pellets are appropriately sized for their mouths to prevent them from choking or not eating properly.
Frozen Foods: These cichlids also enjoy frozen foods such as bloodworms, brine shrimp, daphnia, and mysis shrimp. Frozen foods are a great way to add variety to their diet, ensuring they get a balanced intake of proteins and fats. It’s best to defrost the food before feeding to prevent any potential harm to the fish.
Live Foods: Herichthys carpintis can be fed live foods like earthworms, small feeder fish, and live brine shrimp. Live foods are an excellent source of protein and help encourage natural hunting behavior. However, be careful with live feeders, as they may introduce diseases into your tank. Always source live food from a reputable supplier.
Vegetables: While Pearlscale Cichlids are primarily carnivorous, they can benefit from the occasional vegetable or plant matter. You can offer blanched vegetables like zucchini, spinach, and peas, which provide essential fiber and nutrients. These should be given sparingly, as the cichlids’ main diet should still focus on proteins.
Algae: Herichthys carpintis will graze on algae in the tank, especially in aquariums with live plants. They won’t rely on algae as their primary food source but will nibble on it when available. A well-maintained tank with some algae growth can help supplement their diet, especially if they are housed with other species that help control algae.
Feeding Schedule: A feeding schedule of 2-3 times per day is ideal for Herichthys carpintis. They can be fed smaller portions more frequently to ensure they aren’t overeating or leaving food to pollute the tank. Young or growing fish may require more frequent feedings compared to adults. Always monitor the amount of food you give to avoid overfeeding.
Supplemental Foods: To further enhance their diet, consider adding high-quality sinking pellets or gel foods packed with essential nutrients. Offering occasional treats like shrimp or high-protein food can boost their color and health. During breeding, adding extra protein can help support the energetic demands of the fish.
Tank Parameters
Tank Size: A minimum tank size of 55 gallons (208 liters) is recommended for a single Pearlscale Cichlid (Herichthys carpintis). This provides them with enough space to establish a territory and swim comfortably. If you plan to keep multiple Herichthys carpintis, you’ll need a much larger tank (75 gallons or more) to prevent territorial aggression.
Tank Length and Measurements: The tank should ideally be long rather than tall to give the fish plenty of horizontal swimming space. For a 55-gallon tank, aim for a minimum length of 48 inches (120 cm). This provides the necessary space for the cichlid to move around, establish territories, and avoid stress caused by overcrowding.
Water Temperature: Herichthys carpintis prefers a water temperature between 75°F and 82°F (24°C to 28°C). It’s important to maintain stable temperatures, as fluctuations can stress the fish, leading to weakened immune systems and increased susceptibility to diseases.
pH (Acidity/Alkalinity): A slightly alkaline pH level is ideal for the Pearlscale Cichlid, typically between 7.0 and 8.0. This is in line with their natural habitat, where the water tends to be more neutral to alkaline. Avoid large swings in pH, as this can cause stress and impact their health.
KH (Carbonate Hardness): Herichthys carpintis does well in water with moderate carbonate hardness (KH). A KH of 6–12 dKH is ideal. This helps maintain stable pH levels and ensures the fish are comfortable. Too low or too high KH can cause pH instability, leading to stress.
GH (General Hardness): The Pearlscale Cichlid thrives in moderately hard water. Aim for a GH level between 10 and 20 dGH. This mimics their natural environment, where water hardness is usually moderate. Soft water can cause issues with their health, and extremely hard water can lead to mineral buildup in the tank.
Hardiness: Herichthys carpintis is considered a hardy species that can adapt to a variety of freshwater conditions as long as the water is clean and stable. They are more tolerant of changes in water parameters compared to some other cichlids, but it’s still important to avoid drastic shifts to prevent stress.
Nitrate (NO3) Levels: Nitrate levels should be kept as low as possible, ideally below 20 ppm, with a maximum level of 40 ppm. High nitrate levels can stress the fish, hinder their immune system, and lead to poor water quality. Regular water changes, proper filtration, and avoiding overfeeding will help maintain low nitrate levels.
