Cat-eLog Data Sheet
Scientific Name	**Corydoras hastatus** Eigenmann & Eigenmann, 1888
Common Name(s)	Tail Spot Pygmy Cory
Type Locality	Villa Bella (= Parintins, 2°38'S, 56°45'W), Amazonas, Brazil.
Type Locality Map
Pronunciation	Kory DOOR ass - hass TATT uss
Etymology	Cory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. The specific epithet is from the latin hastatus meaning spear-shaped.
Species Information
Size	32mm (1.3") SL. Find near, nearer or same sized spp.
Identification	Corydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras. One of three species of pygmy cory (C. habrosus, hastatus and pygmeaus respectively). This species has a defined tail spot at the caudul penducle. Faint lines along the lateral line of a beige/grey colour run to the gill cover. The outer eye is usually a blackened colour making the actual eye itself look larger. The only pygmy species with the black rhombus shape at the base of the tail and without a horizontal stripe or dashes along the flanks.
Sexing	The traditional ''birds eye'' view over the cory is an easy way of differentiating sexes. After feeding well and breeding condition is reached, the plumpness of the females is often more noticeable than on other larger cory species due to the overall smaller size of these fish.
General Remarks	First collected in 1865 by Professor Louis Agassiz, a famous zoologist.
Habitat Information
Distribution	South America: Brazil: Rio Guapore Amazon, Middle Amazon (Solimoes) , Madeira, Mamoré, Guaporé (hover or click on these areas to show maps or find other species found there)
pH	6.8 - 7.6
Temperature	22.0-26.0°C or 71.6-78.8°F (Show others within this range)
Other Parameters	No current is preferred.
Husbandry Information
Feeding	Small foods such as crushed flake and micro pellets are suggested for normal care. Daphnia or similar smaller live foods are required to bring these fish into condition.
Furniture	Sandy substrate is best, the small size means that normal gravel can be a bit large for them to sift through. One species of Corydoras for which plant cover is strongly recommended.
Compatibility	A very lively species of cory. Best kept in shoals of at least 6 to gain the benefits of the species. Active in the mid-water a lot of the time. The fish are often too small to cause hassle to other slow swimming species.
Suggested Tankmates	Despite the typical spiked fins, make sure that no other fish can fit one in its mouth! Such a small fish as this Cory can become a meal all too quickly, best kept with smaller tetras such as neons, hatchetfish and pencilfish.
Breeding	The spawning usually follows the typical 'T' position but has on occaision been reported to occur in mid water. A small amount of eggs of about 1mm are laid singly.

At that temperature the fish became moribund, and only 3 out of 10 recovered when temperature increased. I know this because I kept mine outdoors in a plastic tub over the summer and brought them inside one night too late in the fall.", (41) Coriequest, (42) wackytpt, (43) madtundra (k: 25), (44) mace, (45) CaliCory (k: 11), who also notes: "F0 spawning group.
