Telmatochromis burgeoni

Overview

The Telmatochromis burgeoni, known as Burgeon's Telmatochromis or T. burgeoni among enthusiasts, is a territorial Lake Tanganyika cichlid. The offered size is a supply-size option, not a promise that the fish stays at 4 cm. The nominal species is treated as Telmatochromis temporalis in scientific literature, with a reported maximum of 10.2 cm total length. Smaller forms also occur in the aquarium trade, so allow room for adult growth without assuming a particular form. Requiring a minimum 60-litre aquarium and hard, alkaline Tanganyikan water, this semi-aggressive cichlid suits dedicated keepers seeking authentic East African species in a carefully planned aquarium. Endemic to Lake Tanganyika's rocky shorelines, this cave-spawning species establishes territories and displays fascinating breeding behavior in properly structured aquariums. Plan its aquarium around adult growth and territorial behaviour, rather than the selected supply size alone.

Appearance

Telmatochromis burgeoni displays the compact, robust proportions characteristic of small rock-dwelling Tanganyikan cichlids, with a proportionally large head and alert, intelligent expression. Base coloration typically ranges from tan to grey-brown with darker irregular markings providing effective camouflage against rocky substrates. Males may show slightly more intense coloration and marginally larger size than females, though sexual dimorphism remains subtle in this species. The selected supply size does not establish an adult maximum; body size and proportions change as the fish matures. While not displaying the electric blues and yellows of some Tanganyikan species, the refined proportions, interesting patterning, and bold behavior create substantial appeal, particularly when observed exhibiting natural territorial behaviors in rocky aquascapes scaled appropriately for their diminutive dimensions.

Natural Habitat

Endemic to Lake Tanganyika in East Africa, Telmatochromis burgeoni inhabits rocky shoreline zones where complex boulder formations create countless caves, crevices, and territorial niches perfectly scaled for this tiny species. The lake's unique chemistry—pH 7.5-8.5, very hard water, exceptional clarity, and remarkably stable temperatures of 23-27°C—has driven the evolution of extraordinary cichlid diversity with over 250 endemic species. Rock crevices provide shelter and spawning sites, but do not eliminate territorial competition. The species establishes territories centered on preferred tiny caves where it shelters, spawns away from threats, and ambushes microscopic invertebrate prey passing by cave entrances.

Aquarium Setup

The listed 60-litre minimum should not be read as a guarantee that a pair or group will coexist. Allow additional space for adult growth and separate territories, and monitor aggression closely. Create an authentic Tanganyikan rocky biotope using rocks stacked to form multiple tiny caves and crevices sized for the fish as it grows. Ensure rock structures are stable despite small size. Provide more territories than the number of fish to reduce competition. A fine sand substrate mimics the natural lake bed. Avoid plants as they're inconsistent with authentic Tanganyika biotopes. Install efficient filtration providing 6-8x tank volume turnover per hour to maintain the exceptionally high water quality Tanganyikan cichlids require, with moderate water movement but avoiding excessive current that could stress such small fish.

Water Parameters

Replicating Lake Tanganyika's specialized chemistry is absolutely essential regardless of fish size. Maintain pH between 7.5-8.5 using alkaline buffering substrates such as coral sand or aragonite, preventing any pH drops that severely stress Tanganyikan cichlids. Keep hard, alkaline water stable; this guide uses 12-20 dGH, easily achieved in many UK regions with naturally hard tap water, or through remineralizing RO water with Tanganyika-specific mineral supplements. Temperature should remain stable within 23-27°C. Conduct weekly 25-30% water changes to control nitrate accumulation below 40 mg/L while maintaining stable alkalinity and hardness. Ammonia and nitrite must always measure 0 ppm, requiring mature biological filtration. Do not judge filtration and maintenance needs from the supply size alone; allow for growth and maintain stable water quality. For help understanding pH, GH and KH, read our water chemistry guide.

Feeding

Offer Telmatochromis burgeoni varied foods, including small protein-rich items replicating the microscopic invertebrates and zooplankton it consumes in Lake Tanganyika. Match food size to the fish’s mouth; small pellets may be easier to take than large cichlid pellets. Feed quality micro-pellets or crushed small pellets as the staple, supplemented several times weekly with frozen or live meaty foods including baby brine shrimp, daphnia, cyclops, and other tiny invertebrates. Larger foods like adult mysis shrimp may need chopping to appropriate size. Offer variety rather than assuming an exclusively carnivorous diet. Feed small portions 3-4 times daily, ensuring all food is consumed within a few minutes. The tiny mouth size and high metabolism mean frequent small feedings work better than larger infrequent meals, maintaining superior water quality while meeting nutritional needs.

Behaviour

With its territorial nature, Telmatochromis burgeoni displays bold territorial behavior characteristic of much larger cichlids, with individuals or pairs defending tiny caves and the immediate surrounding area against conspecifics and other cave-dwelling species. Aggression levels are semi-aggressive—the species shows surprising assertiveness even when young, readily confronting fish several times its size if they venture near defended caves. Territorial defense intensifies during breeding periods when pairs guard spawning caves with extraordinary intensity. The species demonstrates intelligence and personality, learning to recognize feeding schedules and individual keepers. Much of its time is spent monitoring territories from cave entrances, investigating potential food items, and watching for threats. Observe territorial behaviour as the fish grows and adjust stocking or separate individuals if necessary.

Tank Mates

Compatible tankmates are restricted to other small, similarly tempered Lake Tanganyikan cichlids in suitably large, well-structured aquariums. Shell-dwelling Lamprologus species (L. ocellatus, L. brevis), other tiny Telmatochromis species, and small Julidochromis varieties work in appropriately sized aquariums with extensive territory structure. Small Tanganyikan catfish can work if the tank is large enough and territories well-defined. Completely avoid small peaceful fish despite this species' own tiny size—semi-aggressive temperament means peaceful species suffer harassment, very aggressive cichlids that may injure or kill, fin-nipping species, and any species requiring soft acidic water—complete incompatibility. Tankmate selection requires enough space for adult fish as well as compatible Tanganyikan water conditions and behaviour.

Breeding

Telmatochromis burgeoni is typically a cave or crevice spawner, with bonded pairs defending territories and spawning in the tightest sheltered locations appropriate to their current size. Provide rockwork creating numerous tiny cave systems and crevices where pairs can spawn in complete privacy and security. Parents may guard eggs and fry, with the pair requiring stable Tanganyikan water conditions and good water quality. Spawning often occurs completely out of view in the most inaccessible locations. Eggs hatch within 2-3 days, with fry becoming free-swimming approximately one week later. The challenge with this species is the extremely small fry size, requiring infusoria or liquid fry food initially before progressing to newly hatched baby brine shrimp (nauplii) and microworms. Raising fry demands dedication to water quality and specialized small foods, making breeding an advanced undertaking despite the parents' modest size.
