Cat-eLog Data Sheet
Scientific Name	**Tatia intermedia** (Steindachner, 1877)
Common Name(s)	None
Type Locality	Marabitanos, Pará, Brazil.
Synonym(s)	Centromochlus intermedius
Pronunciation	TA tee ah
Etymology	Tatia: Named after the ichthyologist C. Tate Regan.
Species Information
Size	130mm (5.1") SL. Find near, nearer or same sized spp.
Identification	T. intermedia is often confused with T. galaxias. Both species have dark base with light spots, but on T. intermedia spots are off-white and fade with age. In T. galaxias the spots are bright white, and the body is velvety black. The body shape of T. galaxias is also more slender.
Sexing	Mature males exhibit modified anal fin copulatory organ.
Habitat Information
Distribution	South America: Amazon River basin and rivers of Guianas. Amazon (hover or click on these areas to show maps or find other species found there) Guyana Waters, Coastal Rivers of Guyanas (hover or click on these areas to show maps or find other species found there)
Temperature	22.0-28.0°C or 71.6-82.4°F (Show others within this range)
Husbandry Information
Furniture	As the common name for this family, woodcat, implies, these fish like pieces of wood with crevices and gaps to squeeze into.
Breeding	Has been bred several times by different people. Large number of eggs kept together by a kind of jelly. These eggs are not eaten by the adults and hatch within a few days. Planet Catfish user Daniel Blom was able to prove that a female deposited fertile eggs without a male specimen around, thus indicating that this species also has internal fertilization, a fact which was (is) doubted by scientists.
