Hardhead Pike Cichlid Care Guide
Crenicichla saxatilis, the ringtail pike cichlid, is a predatory species widespread in northern South America, reaching about 20 cm.
Compiled by Aquairi from published sources · Published · Updated
Overview
Crenicichla saxatilis (Linnaeus, 1758), the ringtail pike cichlid, is a predatory cichlid from South America. According to FishBase it occurs in Atlantic coast drainages of Suriname, French Guiana, Guyana, Venezuela and Trinidad. It reaches a maximum standard length of about 20 cm and was originally described by Linnaeus as Sparus saxatilis.
Taxonomy
- Family: Cichlidae
- Genus: Crenicichla
- Scientific name: Crenicichla saxatilis
- Common synonyms: Ringtail Pike Cichlid
- Described by Linnaeus in 1758 (as Sparus saxatilis)
Habitat
It is a benthopelagic freshwater species that frequents creeks and sometimes rivers, particularly during the dry season. Like other pike cichlids it ambushes prey from cover near sunken wood or rocks.
Tank requirements
- Minimum tank volume: 300 L
- Temperature: 24-28 °C (75-82 °F)
- pH: 5.5-7.5
- GH: 2-12 °dGH
- Lifespan: 7-10 years
Diet
Crenicichla saxatilis is described by FishBase as a formidable predator that consumes mainly aquatic insects, fish and plant material; its trophic level is about 3.3. A carnivore diet is required in captivity.
Compatibility
This is an aggressive, territorial mid-water predator; FishBase notes it is unpopular in aquaria because of its aggression. Small fish, tetras and shrimp are treated as prey and should be avoided. Large robust companions such as big plecos, silver dollars and oscars are more appropriate in a spacious tank.
Breeding
Like other Crenicichla, it is a cave-spawner. Breeding is considered intermediate in difficulty and benefits from a structured aquarium with secure spawning sites.
Conservation status
IUCN Red List: Least Concern (assessed 28 October 2020, per FishBase).
Crenicichla saxatilis Breeding Guide
Overview
Crenicichla saxatilis is a medium-sized predatory pike cichlid of the Atlantic coast drainages of Suriname, French Guiana, Guyana, Venezuela and Trinidad, according to FishBase. It reaches about 20 cm and FishBase notes it is a formidable predator feeding on aquatic insects, fish and some plant material. As with other members of the genus it is a cave spawner.
Sexing
External breeding-specific sexual differences for this species are not detailed in the consulted scientific sources. In the genus, ripe females typically become more colourful and rounder in the belly, which is the practical cue used to identify a spawning-ready female.
Conditioning
FishBase records a carnivorous trophic level for this predator, so it should be conditioned on meaty live and frozen foods. A spacious tank with stable water chemistry is needed to bring a pair into condition while managing the species' aggressive temperament.
Breeding Setup
Provide caves and firm cover in warm water. FishBase reports the species in waters around 25-30 C with neutral pH near 7.0 in the wild, so warm, clean, moderately soft to neutral water with secure spawning caves suits a breeding attempt.
Spawning Behavior & Trigger
FishBase lists reproduction categories for the species but provides no specific spawning data. As a cave-spawning pike cichlid the female would attach adhesive eggs inside a cavity, following the genus pattern documented for relatives such as C. compressiceps and C. lugubris, with warm, clean water acting as the practical trigger.
Egg & Fry Care
Detailed egg counts and fry timelines for this species are not documented in the consulted sources. Pike cichlids of this group typically display biparental brood care, with both parents guarding the cave, so similar behaviour would be expected here.
Common Challenges
FishBase notes the species is not very popular among aquarists because of its aggressive behaviour, and that aggression makes safe pair formation the main obstacle. The scarcity of detailed breeding reports means keepers should monitor water quality closely and expect variable outcomes.
