Corydoras davidsandsi, Black, 1987
Origin:South-America, Brazil, middle Rio Negro(according to Allen), Hierronimus reports Rio Unini and Rio Inambu. Lambourne just mentions Rio Inambu.
Etymology: After David Sands.
Synonyms:None.
First import: Unk
Description:Longsnouted corydoras from the Aeneus-group. James Allen wrote about this specie: "It has the same colouration as C. metae from the river of the same name in Colombia but davidsandsi has a longer snout and the black stripe carries on into the bottom lobe of the caudal fin, while C. metae stops short at the caudal peduncle. The C. melini connection has melini having the same black body stripe ending on the bottom lobe of the caudal fin, but the stripe separates just behind the dorsal fin and continues as two lines over the back of the body. The colouration is also different with melini being a dirty white with black specks to the edges of the body scutes, while davidsandsi has a tan colouration with no specks."
Care:A 60 cm tank with good filtration, although no strong current is neccessary for the animals well-being. Dark soil with little light is highly appreciated, as well as soft acidic water. Some floating plants and driftwood . Wildcaught specimens need lots of hideouts to reduce stress.
Temperature:24 degrees
Feeding:Will eat all general food.
Size: 6.5 cm
pH: 6.5-7.5 Hardness: 2-10
Breeding:Allen bred these fish by doing a 75% waterchange which also dropped the temperature 5 degrees Celsius, with part rainwater in combination with a powerhead added to the tank. Since he already used soft and neutral water the current may have been the key factor to get them to spawn, since prior attempts failed. Not very productive. It seems to be a difficult species to breed
Sexual dimorphism:Males are shorter and smaller than the females.
Prices:unk
Additional:Hierronimus describes this fish occurs together with Pimelodella rambarrani.
Picture references: Jan Bukkems.
