1 .- SCIENTIFIC NAME: Ectodus descampsii
2 .- DISTRIBUTION: covers the costs of Zambia and the southern part of Tanzania.
3 .- GEOGRAPHICAL VARIETIES:
4 .- HABITAT: in sandy (sand)
5 .- MORPHOLOGICAL DIFFERENCES: Ectodus The body is elongated, with a powerful tail fin. Usually obtain a total length of 14 cm in males and females somewhat smaller. Both sexes have a black ocellus ringed blue in the dorsal and ventral fins and an odd yellow tinge. Sex differences: Besides being the male slightly larger than females, males tend to be generally more robust and have the largest ocellus on dorsal fin.
6 .- SIZE: about 14 cms.
7 .- INTERSPECIFIC BEHAVIOR: moderate aggressiveness.
8 .- Intraspecific Behavior: Aggressive moderate.
9 .- DIET: Omnivore . In the aquarium accept a varied diet consisting of Artemia, Cyclops, mosquito larva black and some flake food in quality and preferably vegetable content, since they like to pick up some seaweed.
10.-ACUARIO: Inside the aquarium males do not tolerate a member of the same sex unless you have plenty of space (over 150 cm) and can be very aggressive with the females, especially when reproduction. Taking this into account and the fact that these are like swimming a lot, the tank should not be less than 130 cm for a male with several females. The decor should be based on a good layer of fine sand and some rocks that serve as a refuge for females in the incubation period. It is also possible to put some kind of plant as Vallisneria secure, since they can unearth.
11 .- REPRODUCTION: Males construct large nests of sand in a crater of about 40 cm in diameter, which attract females to spawn. Males darken their pelvic fins and throat to become more colorful and so attract females and to direct them toward the nest, while any other intruder will be driven aggressively. If this is successful, the female can hold in your mouth between 15 and 40 eggs, which incubate for 21 days approx. before releasing their fry. Usually prefer the hours of little sun for his productions (dawn, dusk).
12 .- OTHER INTERESTING FACTS: The molecular phylogeny has shown that Ectodus is more related to species such as opthalmotilapias, Cyathopharynx or aulonocranus that Xenotilapia or callochromis, forming a subfamily (Koblemuller, 2004).
13 .- DIFFICULTY: 3
