Care
The Compressiceps Dwarf Pike Cichlid is a rheophilic species known from the fast-flowing waters of the lower Rio Tocantins basin. This elongate, dwarf cichlid must be provided with specialised conditions if it is to thrive in the home aquarium; indeed, a requisite for their care is highly oxygenated, warm water with plenty of current, and tight fitting coverslides are a must. These fish are strong swimmers and are somewhat aggressive, so require a large aquarium compared to their adult size. Provide a soft sandy substrate along with plenty of nooks and crannies formed from piles of pebbles, rocks, pieces of smooth slate, and tangles of driftwood - ensuring that there are some broken lines of sight for the fish to set up territories. Plants are not found in any great abundance in the fast-flowing waters of the natural habitat of W. compressiceps, so are not considered essential; however, robust species such as Anubias and Microsorum tied onto driftwood will help with water quality and will make the aquarium look more aesthetically pleasing, as well as creating more hiding places. Plants grown in the substrate will be uprooted. The best way to keep these cichlids is either as a known compatible pair, or in dense groups (10+) in more spacious aquaria. Groups that are too small could result in major territorial bickering and subsequent losses. A larger group (housed in a tank with a multitude of visual barriers) will ensure that no one fish bears the brunt of any squabbles and is subjected to constant stress - any arguments will be spread throughout the group. These cichlids will be at their best in a species-only aquarium, but can be kept with other robust, current-loving fish that are of similar size (anything smaller will be regarded as food). Like other species that inhabit fresh running waters, these cichlids will not tolerate a build-up of nitrates within the aquarium and require excellent water conditions at all times if they are to thrive - so powerful filtration and regular partial water changes are essential.

Feeding
Small frozen foods such as bloodworm, white mosquito larvae, vitamin-enriched brineshrimp, daphnia, and Mysis shrimp. Will also take sinking pellets/tablets/granules. These fish have a fast metabolism and require 2-3 feeds per day, but do keep a close eye on water quality.
Breeding
Cave spawner. This species has been bred in the home aquarium. Following an elaborate courtship dance, up to 50 eggs will be deposited/fertilised on the ceiling of a cave, which could be a small rocky crevice or a hole in a piece of driftwood. The eggs should hatch within 3-4 days, with the fry becoming free-swimming several days later. Both adults exhibit great parental care.
