Thick Skin Cichlid (Haplochromis sp. 44)

Haplochromis sp. 44 (Astatotilapia sp. 'thick skin')

The *Haplochromis sp. 44* (commercially known as 'Thick Skin' for the strange and robust conformation of its lips for biting) is one of the most fearless, ruthless and infamous predators of Lake Victoria. Under its deceptively stocky and short appearance (it reaches 10-12 cm / 4-5 inches), the male hides a livery of explosive beauty, with a greenish-yellow body surmounted by a blood red or bright orange belly and fins adorned with huge blinding yellow ocelli (fake eggs). Its notoriety, however, is due to its temperament: the sp. 44 is commonly described as a true "aquatic plague". Although small, it is an irreducible brawler, capable of killing or severely mutilating its peers and of subduing fish twice its size, demanding an expert breeder in the management of hyper-violent hierarchies.

Description

Geographic Origin and Biotope: Endemic to Lake Victoria. It is a "littoral zone" species that populates the shallow rocky bottoms rich in debris, rarely venturing into the open water.

Taxonomy and Morphology: Haplochromis sp. "44" (Thick Skin). It is a provisionally classified species (hence the number 44) and is considered one of the most brutal and well-known representatives of Victorian cichlids. Grows up to 12 cm (4.7 inches).

Social Behavior: Fierce, sociopathic and relentless. SP-44 males are proverbial for their unprecedented territorial hyper-aggressiveness. They will kill rivals and stress females to death if space is insufficient. Requires calculated over-stocking to dilute the violence.

Coloration and Sexual Dimorphism: Chromatically explosive. Dominant males have a bright green-gold back and the belly, including the lips, is brick red or blood orange, crossed by dark vertical bands. Females are dull, of a modest uniform olive-sand color.

Care and observations

Aquarium Setup: Do not try under 300 liters (120 cm / 4 feet / 80 gallons). Set up real uninterrupted walls of perforated rocks up to the surface to break the line-of-sight of the Alpha male. Mandatory piles of stones in which pursued females can take refuge.

Diet and Feeding: Opportunistic Carnivore/Omnivore. Absolutely voracious. In nature it scrapes debris and tears off small insects. In the aquarium it needs a base of cichlid pellets rich in spirulina, alternated with mysis and brine shrimp. Hunger is never a problem.

Water Quality: Extreme robustness. Requires African Great Lakes parameters: high hardness (GH 10-20), alkaline water (pH 7.5-8.5) and 24-28°C (75-82°F) temperature. Intolerant to acidic water which causes loss of color and lethargy. Strong water movement.

Compatibility and Tankmates: Will kill or try to hybridize with any other Haplochromis. Keep only with equally brawling Malawi Mbuna capable of defending themselves (e.g. Pseudotropheus, Melanochromis) in overcrowded tanks with large filters, or strictly in a monospecific aquarium (Harem).

Aquarium Reproduction: Maternal Mouthbrooder. Guaranteed and lightning-fast reproduction if the female is not killed by the male during the brutal courtship. It is often necessary to catch the female with her mouth full (stripping) and isolate her to guarantee her survival after giving birth.

Risks and Diseases: The main cause of death in this species is murder perpetrated by the dominant male against submissive males or non-receptive females. From a pathological point of view, they border on immortality and rarely get sick.

Fish profile

Temperament
Violento, mordace e incredibilmente coraggioso. Nessuna vasca è abbastanza grande per due maschi adulti di sp. 44: ingaggeranno combattimenti bocca a bocca e morsi ai fianchi letali. Se incrocia pesci timidi o placidi, diventerà il flagello dell'acquario mangiandogli letteralmente le pinne (fin-nipping aggressivo).
Diet
Onnivoro Carnivoro. Dispone di denti robusti ('pelle spessa') specializzati nello strappare larve, grossi insetti e occasionalmente raschiare detriti vegetali nel lago Vittoria. Necessita di mangimi proteici robusti: pezzetti di gambero, cozze macinate, krill, chironomus e pellet carnivori. Sconsigliato l'eccesso di scaglie vegetali africane pure.

Sex ratio
Harem Gigante (1 Maschio e non meno di 5-6 femmine). Il maschio è un molestatore infaticabile. Le femmine (come in tutti gli Haplochromis del Vittoria) sono color topo-sbiadito, argentate o verdognole, prive del ventre rosso sangue maschile. Acquistare una o due femmine significa condannarle a morte certa.
Feeding frequency
1-2 volte al giorno. Estremamente vorace.
Bioload
Medio-Alto (Grande voracità, escrezioni pesanti).
Flow
Corrente Moderata. Buona ossigenazione superficiale ma senza i vortici degli estuari fluviali.
Jump risk
Covered tank required
Reproduction
Incubatori orali materni. Ibridatori formidabili e letali: MAI mescolare con Astatotilapia o Pundamilia del Vittoria (Nyererei compreso), per nessuna ragione, distruggerebbero il corredo genetico raro con accoppiamenti misti in un pomeriggio. La madre protegge le uova nella gola e va spostata in una rocciata o in un acquario nido se si vogliono salvare i piccolissimi 'Thick skin'.
Compatibility
Mantenimento Specializzato. O 'Species Tank' puro per il Vittoria, oppure mescolato a grossi e robustissimi Mbuna del Malawi (es. Labeotropheus o Labidochromis di mole) che possano resistere ai suoi morsi e alle sue testate continue. MAI con i pavoni pacifici (Aulonocara) o i Delfini (Cyrtocara) che si vedrebbero strappare gli occhi e sventrare il corpo da questo piccolo ma letale lottatore.
