A stunning Lake Malawi Haplochromine cichlid. They are famously associated with the 'Zimbawe Rock' collection point. In the wild, they inhabit caves, and in the aquarium, they appreciate rockwork. Relatively peaceful for a Malawi cichlid, they do well in all-male Hap/Peacock displays or in species-specific harems.

Sulphur Crest Lithobates Varieties
Each variety inherits the species defaults above. Only differences are highlighted.

Males develop a spectacular dark blue body paired with a thick, striking yellow/sulphur 'blaze' running from the nose, over the head, and along the entire dorsal fin. Best kept strictly as one male per tank to avoid conspecific aggression.
Differs in 3 traits from base species
Also known as: Show Male, Sulphur Crest
Female
Females are much smaller and retain a drab brown or silver/grey coloration with three prominent melanic spots along the flank. If kept with a male, a harem of 3+ females is highly recommended to disperse breeding harassment.

Sulphur Crest Lithobates Care Guide Summary
The Sulphur Crest Lithobates, scientifically known as Otopharynx lithobates, belongs to the Cichlids - African family group. Adults reach a maximum size of approximately 16 cm and have a fusiform body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a high level of biological waste.
To thrive, the Sulphur Crest Lithobates requires a freshwater only aquarium with a minimum volume of 250 litres and a tank length of at least 120 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 7.8–8.6 and a general hardness of 10–25 dGH. A moderate water flow is preferred.
The Sulphur Crest Lithobates is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Male and Female. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Sulphur Crest Lithobates Habitat Setup
When setting up an aquarium for the Sulphur Crest Lithobates, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour.
Sulphur Crest Lithobates Compatibility Notes
Classified as semi-aggressive, the Sulphur Crest Lithobates is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, conspecific aggression can be intense, especially in smaller tanks and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Fish Similar to Sulphur Crest Lithobates
Malawi Gar
Lichnochromis acuticeps
An elegant, predatory Haplochromine cichlid from Lake Malawi, named for its elongated, torpedo-shaped body and pointed snout. While it is a true piscivore that will hunt small fish, it is surprisingly peaceful toward other similarly sized cichlids. A fantastic centerpiece for a large 'Hap and Peacock' setup.
Livingston's Cichlid
Nimbochromis livingstonii
A large, highly predatory African cichlid (Haplochromine) from Lake Malawi. Famous for its unique ambush hunting strategy called thanatosis: it lies flat on the sand substrate pretending to be dead to lure small fish, then snaps them up. They require hard, alkaline water, a very large tank, and a sandy substrate to exhibit natural behaviors. Anything that fits in its mouth will be eaten.
Yellow Lab (Mbuna)
Labidochromis caeruleus
The Electric Yellow Lab is one of the most popular and widely kept African Cichlids from Lake Malawi. Classified as an Mbuna (rock-dwelling cichlid), they are famous for their vibrant yellow coloration and striking black dorsal stripes. While considered one of the most 'peaceful' Mbuna, they are still highly territorial cichlids that require hard, alkaline water, a sandy substrate for digging, and abundant rockwork to establish territories.
Trewavas' Cichlid
Labeotropheus trewavasae
A distinctive, rock-dwelling Mbuna from Lake Malawi easily identified by its fleshy, overhanging snout. They use this specialized mouth to scrape algae (aufwuchs) from rocks while remaining parallel to the surface. Highly active and aggressively territorial, they require a heavily rock-scaped tank, hard alkaline water, and a strict herbivorous diet to prevent 'Malawi bloat'.
Peacock Cichlid (Aulonocara)
Aulonocara sp.
Endemic to Lake Malawi, Peacock Cichlids are highly sought after for the breathtaking colors of the males. They are benthivorous, using sensory pores on their jaws to hunt small invertebrates in the sand. While territorial, they are generally peaceful compared to their aggressive Mbuna cousins. They require hard, alkaline water and a sandy substrate to prevent gill damage while sifting.
Malawi Eyebiter
Dimidiochromis compressiceps
A large, highly specialized predatory cichlid endemic to Lake Malawi. Named for its legendary habit of biting the eyes out of prey (though it mostly swallows smaller fish whole), it features an extremely compressed body used to camouflage among reeds before ambushing its target. Males turn brilliant metallic blue, while females remain silver.
