Aequidens curviceps, Ahl, 1924
Origin:South-America, Amazon river and tributaries. Not present in Peru and Bolivia.
Etymology: Curviceps; refers to the bent stripe?
First European import: Germany, Hamburg, 1909 by Siggelkow
Description:See pictures. The stripe that is visible can also appear as three large spots, or completely disappear depending on the mood of the fish.
Care: Very suitable for the community tank, the fish can be kept in a well planted tank even together with small fish. As long as the fish are fed well, neither plants nor other inhabitants are bothered. In smaller tanks only one pair should be kept, but in larger tanks several pairs can be kept, as long as there are enough hideouts, formed by stone and driftwood formations. Temperatures in the lower regions, 21-23 degrees, hardness below 20dGH, pH around neutral.Aequidens curviceps is susceptible to diseases in foul water, monthly waterchanges are required.
Feeding:Omnivorous, all food is taken.
Size:Up to 9.5cm, in aquariums usually up to 8cm.
Breeding: Aequidens curviceps will often spawn without any special care in community tanks. To breed the fish place apair in a 60cm tank, which should be well planted on the sides, and have some free space in the middle. Watervalues are not really important, as long asas the water is fresh, and not too hard. Place some flat stones on the bottom, which the fish will use to spawn, although they will also spawn on plant leaves or driftwood.There's no need to raise the temperature, the fish will spawn just as well at 18 degrees as at 25 degrees. Up to 300 eggs will be laid, which are protected by both parents, and will hatch in 2-4 days, depending on the temperature. Aequidens curviceps fry are easy to raise, and will immediately eat artemia nauplii.
Sexual dimorphism:Males are larger, more colorful, and have elongated dorsal and anal fins.
Prices: Netherlands: 3€
Additional:Although the fish used to be very popular, it is now rarely seen. Piture 1 and 3 may be another species, picture 2 definitely is Aequidens curviceps.
