this giant species has been exported out of South America for years and as with most strigata/lugubris group fish it is usually sold under the wrong name of C. strigata. The real C. strigata occurs only in eastern Brazil near the Rio Tocantins area. The real C. strigata is also a greener fish with a distinct ocellated humeral blotch. This fish does not display much of a humeral blotch. This fish requires a very large tank and clean water. Poor water quality leads to hole-in-the-head disease. Once pair bond has been established, the pair does not harm each other, but unpaired fish and sub adults are viciously intolerant of each other. Despite the name, this fish is usually exported from Colombia and the attractively colored juveniles, with the spotted heads and a prominent lateral band, are often sold as Black Line pikes. Juveniles are easy to keep and gregarious but with maturity comes an ontogenic color change and a drastic loss of aquarium manners. This is when most aquarists give up on this species. A large tank with numerous hiding places and some luck may result in a compatible pair.
The Venezuela Pike Cichlid is the largest member of the Lugubris group. They are native to the Rio Orinoco and its Amazon tributaries in Venezuela and Columbia, South America. As juveniles the Venezuela Pike Cichlids have multiple dark spots on their cheeks, heads and operculum; they also display a prominent lateral band of varied intensity and often have a red hue along the top of their entire dorsal fin. Once they reach maturity the Venezuela Pike Cichlid will experience an ontogenic color change and will lose most of their juvenile coloration and markings, eventually ending up with a solid, pale gray-blue coloration, bright red eyes, a faint darkened area instead of a humeral blotch and a prominent, black ocellus spot at the beginning of their caudal fin; in addition, once out of their juvenile stage this species will completely lose its manners and will start to become increasingly aggressive as it approaches its full size. The juveniles and adults are both very attractive and although the Venezuela Pike Cichlid is a popular species in the hobby, they are rarely found among local retailers; the best method to acquire a specimen is through online auctions and vendors.
Venezuela Pike Cichlids are the largest of their species and are extremely fast and powerful; they require a 90 gallon aquarium with a tight fitting lid. Provide a sandy to small gravel substrate, at least one large piece of driftwood along with several smaller pieces, possibly some rock structure, and a decent amount of live plants ranging in size from micro to large Amazon swords. Venezuela Pike Cichlids can tolerate the light intensity needed for the larger plants , but does prefer to have shaded areas via floating vegetation or cave-like structures of driftwood or rock. They prefer "blackwater" conditions and tend to thrive in the higher end of their temperature threshold; they also tend to prefer a lower pH as well as soft water and pristine conditions are in high demand. Because they are large, fast, and powerful, they also require adequate open space for hunting and swimming. Venezuela Pike Cichlids should be considered extremely aggressive and territorial, therefore potential tank mates should be considered carefully and planned out in advance; it's recommended that tank mates actually be added before the pike specimen itself, or at the very least... at the same time. Some suggested tank mates include medium to large Pleco species, true Parrot Cichlids, Lima Shovelnose Catfish, larger Oscars, and Peacock Bass.
Venezuela Pike Cichlids are Piscivorous and will initially only prey upon live fish. Fish are their main food source in their natural habitat, but once in the aquarium, they learn quickly and they also learn from other fish; they can be trained to accept a few other live foods and may eventually be trained to accept frozen or fresh, prepared meaty foods such as chopped krill, vitamin-enriched brine shrimp, and chopped pieces of fish; some specimens may eventually be trained to accept freeze-dried or other prepared food items, but it doesn't always work out. That's not too much of a problem as ghost shrimp and some of the other food items mentioned can be "gut-loaded" and vitamin-enriched in order to provide the Venezuela Pike Cichlids with a varied and well balanced diet.
