Cat-eLog Data Sheet
Scientific Name	**Trachelyichthys exilis** Greenfield & Glodek, 1977
Common Name(s)	None
Type Locality	Río Mamón, a trib. of Río Nanay, about 25 km west of Iquitos, Peru, 3°42'S, 73°16'W.

Species Information
Size	80mm (3.1") SL. Find near, nearer or same sized spp.
Identification	Compared to T. decaradiatus, the positioning of the eyes in T. exilis is almost at the beginning of the head whereas the former has them positioned further backwards (slightly before the middle of the head).
Habitat Information
Distribution	South America: Nanay River basin in upper Amazon River drainage. Amazon, Upper Amazon (hover or click on these areas to show maps or find other species found there) Amazon, Upper Amazon, Nanay (hover or click on these areas to show maps or find other species found there)
pH	6.5 - 7.0
Temperature	22.0-24.0°C or 71.6-75.2°F (Show others within this range)
Husbandry Information
Breeding	Mating in a regular auchenipterid way by clasping. Internal fertilization. Eggs are sticky, yet - contrary to for example those of Tatia species - are not laid in clutches but can be found throughout the tank.
