Crenichla Lenticulata Care Guide
(Spotted Pike Cichlid)
The Crenichla lenticulata, commonly known as the Spotted Pike Cichlid, is a species of pike cichlid native to the Amazon Basin in South America. Known for its elongated body, sharp teeth, and striking spotted pattern, this species is a popular but challenging fish for experienced aquarium hobbyists. Its predatory nature and territorial behavior require careful tank planning and proper care to ensure a successful and healthy environment.
Tank Requirements
- Tank Size:
- Crenichla Lenticulata can grow up to 10–12 inches in length, so a minimum of 75 gallons is recommended for a single individual, though larger tanks (100 gallons or more) are ideal for a group or to house other species alongside it.
- The tank should be long enough to accommodate the fish’s predatory and territorial nature.
- Tank Setup:
- Substrate: Use a soft, smooth substrate, such as sand or fine gravel, which is gentle on their fins and barbels. Avoid coarse or sharp gravel.
- Decor:
- Provide plenty of rocks, driftwood, and dense plantings to offer hiding places and territories. Crenichla Lenticulata is territorial, so they need places to establish their space.
- Include some open swimming areas, as they are active swimmers that also enjoy moving through the tank in search of prey.
- Lighting: Moderate lighting is fine, with some shaded areas created by plants or other decorations. Pike cichlids often prefer a bit of cover to retreat to.
- Water Flow:
- These fish come from slow-moving rivers and streams, so they prefer gentle to moderate water flow. A strong current may stress them, so adjust your filtration system accordingly.
Water Parameters
- Temperature: 75–82°F (24–28°C)
- pH: 6.0–7.5 (slightly acidic to neutral)
- Hardness: 2–15 dGH (soft to moderately hard water)
- Ammonia/Nitrite: 0 ppm; nitrates should be kept below 20 ppm.
- Water Changes: Perform regular 20-30% water changes weekly to maintain water quality. Pike cichlids are sensitive to poor water quality, especially ammonia and nitrite buildup.
Diet
Crenichla lenticulata is a carnivorous predator, and its diet should consist mainly of protein-rich foods. They will actively hunt down their prey, so feeding them requires a bit of effort to replicate their natural behavior.
- Staple Foods:
- High-quality cichlid pellets or sticks formulated for carnivores, ensuring that the food sinks to the bottom of the tank.
- Live or Frozen Foods:
- Offer live or frozen foods such as feeder fish (guppies, minnows), earthworms, bloodworms, and brine shrimp. These will help mimic their hunting behavior.
- Occasional Treats:
- Shrimp, mysis, krill, and small insects are excellent sources of protein for them.
- Feeding Schedule:
- Feed them 1–2 times a day with enough food that they can consume within 3–5 minutes. Overfeeding can cause water quality issues.
Behavior and Compatibility
- Temperament:
- Crenichla Lenticulata is a territorial and predatory fish, which can make it aggressive towards other fish, particularly smaller species.
- They can become highly protective of their territory, especially during breeding.
- In general, they prefer to be the dominant fish in the tank.
- Activity:
- These fish are active swimmers and will patrol their territory, hunting and exploring. While they can be quite stunning with their active movements, they also tend to hide or seek shelter when feeling threatened.
- Pike cichlids are relatively solitary and are known for their ambush hunting style, waiting to strike at unsuspecting prey.
- Tankmates:
- Crenichla lenticulata is not suitable for community tanks with small or peaceful fish. They may view smaller tankmates as food.
- Suitable tankmates include larger cichlids, robust catfish, and other aggressive fish that can hold their own in a territory-dominated environment.
- Avoid keeping them with species that are overly passive or similar in size and temperament.
Breeding
Breeding Crenichla lenticulata in captivity is possible with the right conditions:
- Breeding Tank:
- Set up a separate breeding tank with the same water parameters: soft, slightly acidic water and a temperature around 78–80°F (25–27°C).
- Include smooth, flat surfaces or rocks where they can lay their eggs. Pike cichlids tend to choose these surfaces for spawning.
- Conditioning:
- Condition the breeding pair with high-quality, protein-rich foods, including live foods like earthworms and brine shrimp.
- Spawning Behavior:
- The female will lay eggs on the selected surface, and the male will fertilize them. Both parents are often involved in guarding and protecting the eggs and fry.
- After the eggs hatch, the fry will be cared for by both parents. They may also be moved by the parents to different hiding places for protection.
- Fry Care:
- Once the fry are free-swimming (about 3–5 days after hatching), they can be fed infusoria, liquid fry food, or microworms until they are large enough to accept baby brine shrimp or finely crushed flakes.
Common Challenges
- Aggression:
- Crenichla lenticulata is a territorial predator. Tankmates should be chosen carefully to avoid aggression. Even with other large cichlids, there can be occasional skirmishes for space and food.
- Water Quality:
- As a predatory species, Crenichla lenticulata produces a significant amount of waste, which can lead to a build-up of harmful substances in the tank. Regular water changes are essential to maintain optimal water conditions.
- A strong filtration system is highly recommended to keep the water clean and reduce the buildup of harmful toxins.
- Feeding:
- Feeding Crenichla lenticulata can be challenging, as they require a high-protein, varied diet. If they are not provided with enough live food, they may become stressed or less active.
- Tank Setup:
- These fish need plenty of space, as well as hiding spots and territories. Without enough space, they may become overly stressed or aggressive towards other fish in the tank. Proper tank design is critical for their well-being.
Interesting Facts
- Crenichla lenticulata is known for its beautiful spotting pattern, which provides excellent camouflage in their native environment of the Amazon Basin.
- This species is a cichlid but behaves very similarly to pike fish, using an ambush predator strategy.
- Like many pike cichlids, Crenichla lenticulata is capable of impressive bursts of speed when attacking prey.
- In the wild, these fish are often found near submerged structures such as fallen trees and roots, where they can hide and ambush passing fish.
