Description: See picture
Care: This is a difficult species to keep in the aquarium, and is best not kept in a community tank. It's better to keep 8-10 fish in a 60 cm species tank. The water should be clean and well filtered. Weekly small waterchanges with slighly acidic not too hard water. Floating plants, some driftwood, a sandy soil and a densely planted area in the tank will create a suitable environment for these fish. Aspidoras pauciradiatus are active swimmers, that can be found in any part of the tank, but mostly in the lower and middle regions.
Size: Up to 3.5 cm
Breeding: Has been bred in aquaria. Place a group of ish in a breeding tank with very soft, acidic water(pH 6). Water should be well filtered and rich in oxygen. If the fish are fed well, and the females are noticeably bigger, start doing daily waterchanges. Breeding may be seasonal
Sexual dimorphism: Females are bigger.
Additional: Extremely nice fish for a tank, especially if combined with other tiny fish( Rasbora urophthalma brigittae, Parosphromenus parvulus, Rasbora doriocellata macrophthalma, Nannostomus espei )
