T-Bar Cichlid Care Guide
Cryptoheros sajica is a Central American dwarf cichlid from the Pacific slope of Costa Rica, named for a T-shaped dark mark on its flank.

Overview
Cryptoheros sajica is a Central American cichlid of the family Cichlidae, originally described by Bussing in 1974. According to FishBase, it is endemic to the Pacific slope of Costa Rica. The common name T-bar cichlid refers to its tan body with several indistinct bars: the third bar is usually prominent and, combined with a dark lateral stripe running back from the gill cover, forms a horizontal T-shaped mark. Over time the species has been placed in the genera Cichlasoma, Archocentrus, Cryptoheros and Amatitlania.
Taxonomy
- Family: Cichlidae
- Genus: Cryptoheros
- Scientific name: Cryptoheros sajica
- Author: Bussing, 1974
- Genus combinations in use: Amatitlania sajica, Archocentrus sajica
Habitat
FishBase records the species from rivers and rivulets of the Pacific slope of Costa Rica, at elevations up to about 2,000 feet. It favours moderate to strong currents over smaller rocks and gravel rather than fast rapids. It is a tropical freshwater, benthopelagic fish.
Tank requirements
- Minimum tank volume: 150 L
- Temperature: 24-28 °C (75-82 °F); FishBase reports a wider 23-30 °C range
- pH: 7.0-8.0
- GH: 8-18 °dGH
- Size: 8-12 cm (FishBase max 9.0 cm SL for males)
- Lifespan: 6-10 years
Diet
The species is an omnivore. In the wild FishBase reports it feeds on algal filaments, aquatic insects, seeds and bottom detritus. In aquaria it accepts a varied diet of prepared, frozen and live foods.
Compatibility
It is a semi-aggressive, diurnal cichlid that occupies the middle of the water column. It is regarded as less aggressive than the related convict cichlid but becomes territorial when breeding, so robust tank mates such as other Central American cichlids and armored catfish are more suitable than small tetras.
Breeding
Cryptoheros sajica is a cave or substrate spawner. FishBase reports that it spawns on oblique or vertical surfaces in caves and crevices, producing roughly 300 eggs, with the female tending the clutch; eggs hatch after about three days. Both parents guard the fry, and the young are reported to feed on parental dermal mucus.
Conservation status
IUCN Red List: Vulnerable (assessed 21 September 2019). FishBase notes the species enters both commercial fisheries and the aquarium trade.
Cryptoheros sajica Breeding Guide
Overview
Cryptoheros sajica, the T-bar cichlid (now also placed in Amatitlania), is a dwarf convict relative from the Pacific slope of Costa Rica, where it lives in freshwater streams and lakes with moderate to strong currents at elevations up to about 2,000 feet. Males reach about 12 cm. It is named for the T-shaped mark formed where the prominent third body bar meets a dark lateral stripe running from the gill cover.
Sexing
Mature females ready to spawn develop golden-yellow coloration on the dorsal and anal fins. Males are generally larger.
Breeding Setup
- Provide caves and enclosed spaces; the species uses cave spawning most often but also spawns on open substrate.
- Use sand substrate so the pair can prepare nursery pits.
- Offer line-of-sight breaks to reduce male aggression toward the female.
- A tank of roughly 150 L suits a pair.
Spawning Behavior & Trigger
As they come into condition the pair develops high-contrast breeding colours and displays at a chosen site. While the female cleans the spawning surface the male patrols the perimeter. The female deposits 50-200 eggs depending on her size (reports of up to about 300), which the male fertilises immediately; spawning can continue for over an hour. The female then guards the eggs, fanning them with her pectoral fins.
Egg & Fry Care
Eggs are small and whitish to brownish-transparent for camouflage. They hatch into wrigglers after about 3 to 4 days, and the parents move them to a prepared pit. The wrigglers feed on their yolk sacs and become free-swimming after another 4 to 5 days. The female handles most brood care while the male defends the territory.
Common Challenges
Males can be dangerously aggressive toward an unreceptive female, sometimes harming her before spawning. Provide hiding spots and, if needed, a divider, and ensure the female has escape routes.
