Common name: Therese's sole

Scientific name: Aseraggodes therese Randall, 1996

General information

Therese's Sole, scientifically known as Aseraggodes therese, is a lesser-known but fascinating species for the marine aquarium enthusiast. This small, benthic flatfish is part of the Soleidae family, which is characterized by their flattened bodies and bottom-dwelling habits. They are not commonly found in the aquarium trade, but they can be a unique addition to a peaceful, species-specific or biotope aquarium.

Their cryptic coloration and ability to blend with the substrate make them interesting to observe as they can virtually disappear right before your eyes. This camouflage also serves as a defense mechanism in the wild, protecting them from predators.

Care

Caring for Therese's Sole requires an aquarium with a soft, sandy substrate to mimic their natural habitat and allow for their burrowing behavior. They are sensitive to water quality, so maintaining pristine conditions is crucial. They feed on small crustaceans and worms in the wild, so a diet of live or frozen meaty foods like brine shrimp, mysis shrimp, and bloodworms is recommended.

Reproduction

Little is known about the reproductive habits of Aseraggodes therese in the wild or in captivity. However, like many marine fish, they are likely to have a pelagic larval stage.

Habitat

Aseraggodes therese is found in the Indo-Pacific region, from the Red Sea and East Africa to Samoa, north to the Ryukyu Islands, and south to the Great Barrier Reef. They inhabit sandy bottoms near coral reefs, often at depths ranging from 1 to 30 meters.
