Orange Chromide

Geographical Origin and Habitat: Pseudetroplus maculatus is native to the coastal regions of southern India and Sri Lanka. It inhabits a wide variety of biotopes, including slow-moving rivers, brackish estuaries, coastal lagoons, canals, and paddy fields. This adaptability allows it to thrive in both fully fresh water and brackish conditions, often characterized by sandy bottoms and dense riparian vegetation.

Taxonomy and Morphology: It belongs to the family Cichlidae, subfamily Etroplinae. It features a body that is strongly compressed laterally and almost circular or oval in shape. The head is small with a terminal mouth. It reaches a maximum adult length of about 8-10 centimeters. It is distinguished from African and American cichlids by its Asian origins and particularly robust anal fin spines.

Social Behavior: It is a gregarious species that prefers to live in groups, especially outside the breeding period. It displays a generally peaceful temperament for a cichlid, although it becomes markedly territorial and aggressive during nesting and defense of the offspring. It shows a fascinating symbiotic cleaning behavior with its larger congener, Etroplus suratensis.

Coloration and Sexual Dimorphism: The wild variety has a yellowish coloration with rows of small red dots and three large dark spots on the flanks. The most common aquarium variety is uniform golden orange. Sexual dimorphism is minimal: adult metals may exhibit slightly larger sizes, more pointed dorsal and anal fins, and more intense colorations during the breeding season.

Aquarium Setup: It requires an aquarium of at least 80-100 liters for a pair or a small group. The bottom must consist of fine sand or rounded gravel, as they love to dig during breeding. Numerous hiding places formed by rocks, driftwood, and terracotta pots must be provided. Sturdy plants like Anubias and Vallisneria are recommended, protected at the base to prevent them from being uprooted.

Diet and Feeding: It is an opportunistic omnivore. In nature, it feeds on algae, organic debris, small invertebrates, and other fish eggs. In the aquarium, it must be fed a varied diet including high-quality flake or pellet food, supplemented with frozen foods (such as bloodworms, brine shrimp, and mysis) and plant matter like spirulina or blanched vegetables.

Water Quality: Very adaptable but prefers hard to moderately hard water. Temperature: 20-28°C, pH: 7.5-8.5, GH: 10-25. Although it can live in fresh water, the addition of marine salt to create a light brackish environment (specific gravity 1.002-1.005) promotes optimal health, reduces stress, and significantly intensifies livery colors.

Compatibility and Cohabitation: It can be placed in community aquariums with peaceful medium-sized fish. Excellent tankmates are other brackish water fish like archerfish (Toxotes), bumblebee gobies (Brachygobius), or robust freshwater fish like barbs and danios. Avoid cohabitation with very small or excessively aggressive species.

Aquarium Breeding: Monogamous species that forms stable pairs. Breeding occurs on a flat substrate (rocks or broad leaves). Both parents actively participate in cleaning the site, fanning the eggs (100 to 300), and actively caring for the fry. The young initially feed on the skin mucus produced by the parents before switching to brine shrimp nauplii.

Risks and Diseases: It is sensitive to water value fluctuations and nitrate accumulation. It can easily contract Ichthyophthirius (white spot disease) if subjected to sudden temperature changes. The absence of salt in the water can predispose it to skin fungal infections and fin rot. Maintain regular water changes.
