Etymology

Pseudomugil: from the Ancient Greek ψευδής (pseudes), meaning 'false, lying, untrue', used here as a prefix, and the generic name Mugil. gertrudae: named for t…

Distribution

Described from 'Rivulet in sago forest at Ngaiguli, Terangan, Aru Island, Aru Islands, Maluku, Indonesia', corresponding to the island now normally referred to…

Habitat

Shows a preference for shallow, marginal zones of heavily-vegetated, slow-moving or standing waters of creeks, small streams, lakes, billabongs, and swamps, an…

Aquarium size

An aquarium with base dimensions of 45 ∗ 30 cm or equivalent should be the smallest considered.

Maintenance

Best kept in a densely-planted tank and an excellent choice for the carefully-aquascaped set-up. The addition of some floating plants and driftwood roots or br…

Best kept in a densely-planted tank and an excellent choice for the carefully-aquascaped set-up.

The addition of some floating plants and driftwood roots or branches to diffuse the light entering the tank also seems to be appreciated and adds a more natural feel.

If you wish to raise fry alongside the adults the addition of fine-leaved aquatic moss such as a Taxiphylum sp. is advisable (see 'Reproduction').

The water should be well-oxygenated and a degree of flow is advisable. Do not add this fish to a biologically immature aquarium as it can be susceptible to swings in water chemistry.

Where does this come from?

My own experienceFor example, I've kept twelve in a planted 60 cm tank since March 2024.A website I sawFor example, an IUCN Red List assessment, a museum catalogue or a FishBase page.A paperFor example, Marshall et al. (2011), Water temperature differences in interfluvial palm swamp habitats of Paracheirodon axelrodi and P. simulans.A book, or something not onlineFor example, Tappin (2010), Rainbowfishes: their care and keeping in captivity.Something already on the pageFor example, the Behaviour and compatibility section already says this.

Water conditions

Temperature: 21 – 28 °C pH: 4.5 – 7.5 Hardness:5 – 12 dGH NB: suggested ranges are for the ornamental strain. Wild specimens from specific localities may requi…

Diet

Feeds chiefly on floating or suspended zooplankton, phytoplankton, and invertebrates in nature, and in the aquarium must be offered items of a suitable size. I…

Behaviour and compatibility

Peaceful but unsuitable for the general community aquarium since it's easily outcompeted and quite timid. It’s best maintained alone or alongside fishes of com…

Sexual dimorphism

Males are more highly-patterned and colourful than females and the unpaired fins become noticeably extended as they mature.

Reproduction

This species is an egg-scatterer exhibiting no parental care and will consume its own eggs and fry given the opportunity. Spawning is more likely in temperatur…

Notes

Wild populations of this species tend to be somewhat isolated from one another, and exhibit various, often highly-localised, differences in colour pattern, bod…
