Parauchenipterus galeatus is densely settled in numerous water bodies of the north-eastern part of South America. On the European continent, this fish came back in 1990 thanks to the efforts of the Dutch scientist Wildekamp.
We have this catfish appeared in large fish breeding a couple of years earlier.
The discoverer of the catfish goliath is M. Likhachev, who not only successfully kept catfish at home, but also successfully bred and received, thanks to successful selection, an albino form that was firmly entrenched in the Russian aquarium market.
In nature, catfish goliath reaches puberty by two years of life. Under aquarium conditions, puberty begins a year earlier.
A strong catalyst for development is the high water temperature (27 – 32 degrees). The maximum length of the body in soms does not exceed 20 centimeters, as a rule, the standard length is 15 – 18 centimeters.
However, if you seriously engage in the breeding of this fish, you can achieve a dwarf form, the body length of which does not exceed 10 centimeters.
Males are slightly larger than females and more protracted. On the anal fin, the extreme ray has a special structure that allows for the internal fertilization of the female.
On the back there is a jagged thorn, which helps the male to fix the female during the mating games, when the fish are moving around the aquarium.
The duration of the spawning itself is modest, 30 to 40 minutes maximum. Very often aquarists resort to the use of gonadotropic drugs to stimulate the sexual function of catfish.
After mating, the female catfish is able to self-lay eggs without the help of a male. The fecundity of the female varies from 500 to two thousand eggs, which swell to 6 millimeters in diameter under the action of water. The first attempts to swim the youngsters make a week after hatching.
Starter feed for fry – Nauplii Artemia and Cyclops. Catfish grow very quickly, in a month they grow up to 3.5 centimeters.
P. galeatus eat almost everything: chopped beef, fillet of sea fish, small mollusks, black bread and branded feed. Feed the fish to be dosed, otherwise the catfish overeat, and their body shape begins to resemble a barrel.
Adult soma very often go hunting and eating small fish, respectively, with rasborami or neon of this inhabitant of tropical water bodies to settle in no case.
Somik-goliath is considered a night hunter, therefore, in the aquarium, you need to feed this fish in case of weak scattered light, or after turning off the light in the aquarium. In the daytime, the soma hides in a pile of kagyag, dense thickets of plants and other secluded corners of the relief of the aquarium bottom. In tight shelters (pipes and pots), catfish can be tightly stuck because of splayed fins.
When you catch catfish from an aquarium, always remember the thorns that can hurt you.
The conditions of soma-goliath are as follows:
