Natural habitat

The Round Tailed Paradise Fish inhabit irrigation ditches, marshes, rice paddies, pools, streams, and the slow-moving backwaters of larger rivers. They are found in regions where winter temperatures can drop significantly, causing their habitats to freeze over. Despite this, they are adapted to thrive in colder wetlands with dense vegetation.

Where they are found

This species is native to freshwater habitats in parts of Brazil, Colombia, and Venezuela, where they thrive in both still and flowing waters often near submerged structures.

Aquarium care

A densely planted aquarium of at least 30 gallons is ideal, with a substrate of fine gravel along with some rocks and driftwood for hiding spots. The water temperature should range between 10 to 22°C, closely mimicking their natural habitat.

Feeding

Feed your common pleco a balanced diet comprising high-quality algae wafers, fresh vegetables like zucchini and cucumber, and protein-rich foods such as bloodworms or shrimp. It's important to feed them at night when they are most active.

Compatibility

They coexist peacefully with many community fish, but caution should be taken with smaller species that might fit in their mouths or aggressive fish that could disturb them.

Breeding

They are bubble nest builders, similar to Macropodus opercularis. Males will construct a bubble nest, after which mating occurs beneath it. Soft water with slightly elevated temperatures can trigger breeding behavior.
