Iporanga Eartheater (Geophagus iporangensis) Care Guide
Geophagus iporangensis is a Brazilian eartheater from the Ribeira de Iguape basin, long confused with related coastal species.
Compiled by Aquairi from published sources · Published · Updated
Overview
Geophagus iporangensis is an eartheater cichlid from southeastern Brazil, described by Haseman in 1911. It belongs to the coastal Geophagus assemblage related to G. brasiliensis. Like other eartheaters it feeds by sifting substrate.
Taxonomy
- Family: Cichlidae
- Subfamily: Geophaginae
- Genus: Geophagus
- Scientific name: Geophagus iporangensis
Habitat
According to FishBase the species occurs in the Ribeira de Iguape River basin in Brazil. It is a freshwater, benthopelagic species of tropical climate.
Tank requirements
- Minimum tank volume: 350 L
- Temperature: 18–28 °C (64–82 °F)
- pH: 6.0–7.5
- GH: 5–15 °dGH
- Lifespan: 8–12 years
Diet
As an eartheater the species is an omnivore that sifts substrate to extract small invertebrates and organic material. In the aquarium it accepts fine-grade prepared foods alongside small live and frozen items.
Conservation status
The IUCN Red List classifies Geophagus iporangensis as Least Concern (assessed 18 May 2022).
Geophagus iporangensis Breeding Guide
Overview
'Geophagus' iporangensis (formerly treated as Geophagus brasiliensis iporangensis) is a hardy Brazilian eartheater from the Iporanga region, long confused with G. brasiliensis. According to Seriously Fish it is a biparental substrate spawner, not a mouthbrooder, so the eggs and fry are guarded on the substrate rather than carried in the mouth. This matches the substrate-spawner classification in the species record.
Sexing
Males grow larger than females, often significantly so, and most dominant specimens develop a nuchal hump to some extent. These differences make mature males relatively distinguishable, though pairs are best obtained by growing on a group.
Conditioning
A varied diet and clean, stable water keep adults in condition. The most essential decor item is a soft, sandy substrate so the fish can browse naturally; coarse gravel can inhibit feeding, damage gill filaments and be ingested.
Breeding Setup
- Soft sand with flat rocks or wood as potential spawning surfaces
- Temperature: 20-26 °C (Seriously Fish maintenance range)
- pH: 6.0-7.0 (Seriously Fish)
- Regular water changes to maintain quality
Spawning Behavior & Trigger
As a biparental open/substrate brooder, the pair cleans a chosen surface and both parents guard the eggs and resulting fry on the substrate. Seriously Fish does not list a specific environmental spawning trigger for this species.
Egg & Fry Care
Seriously Fish does not provide species-specific egg counts, incubation duration or a detailed fry-rearing protocol. As a biparental substrate spawner the parents tend the eggs and shepherd free-swimming fry, which are reared on standard small live and powdered foods.
Common Challenges
The species is uncommon in the hobby but adaptable and tolerates a wide temperature range. Because eggs are guarded on the substrate rather than brooded in the mouth, they are more exposed in community tanks, so water quality and territory protection matter.
