Ototsinkly Mottled (Otocinclus flexilis)
Habitat: Ototsinkly speckled inhabits both rapid and calm rivers with dense vegetation and algal formations on the rocks in the south-eastern regions of Brazil.
Description: body spindle-shaped elongated. The swim bladder and adipose fin are absent from this genus of catfish.
Snout pointed, mouth-sucker pointing down. The body is covered with carapace scales.
The color is greyish olive or yellow.
The whole body is dotted with dark spots. Belly light.
From the snout to the caudal fin stretches a longitudinal dark strip, on the tail is a large brown spot.
Females are distinguished by their fullness and larger size.
In the aquarium, the Ototsinkly speckled grows to 5 cm. Their color changes depending on the environment, and their color imitates other catfish, for example, such as Corydoras habrosus or Corydoras paleatus – Mottled catfish.
Arrangement and parameters of the aquarium: Fish are very peaceful and feel most comfortable when keeping a flock of at least 5 or more Ototsinklyus speckled very social form. They become fearful and under stress if they are not contained in groups (in nature they congregate in groups of several thousand) and can die from stress if they are found alone.
It is necessary to decorate an aquarium with a large number of shelters, snags, large stones, dense vegetation. The growth of floating plants should be limited so that they do not completely cover the surface of the water. Medium sand is suitable as a primer.
In the aquarium there should be no decorations with sharp edges.
Water parameters: 22-26 ° C, pH 5-7, dH 4-12.
A very active filtration is required, better through peat, aeration and replacement of a quarter of water every week.
At elevated concentrations of nitrogen compounds dissolved in water, otozinclusses begin to refuse food and rise to the surface of the aquarium.
These fish are excellent attendants and very well clean stones, decorations, plants and glass from algal fouling, therefore they are ideal for keeping in a common aquarium.
Ototsinkly speckled and speckled catfish
Small size Spotted Otozinclus (Otocinclus flexilis) requires careful selection of neighbors, which should be non-aggressive and medium-sized, such as haratsinovye, dwarf cichlids or shrimp. Undesirable content with other algae to avoid competition for food for fish.
The first month is very critical for their survival, so you should immediately create the most favorable conditions.
Can not contain aggressive cichlids and suckers.
Nutrition: Otozinclus prefers algal fouling in an aquarium, primarily diatoms and microscopic aquatic organisms. In relation to feeds it is picky, but it loves more vegetable food, special som tablets with a high content of spirulina are mandatory in the diet.
Feed fish can be lettuce, zucchini, carrots, potatoes and cucumbers.
A portion of the feed is always given before turning off the light.
Reproduction: in the spawning 30-50 liters male and a couple of females.
Water parameters in the spawning aquarium: 25-27 ° C, dH 4-10, pH 6.5-7.
Usually fish spawn in the early morning. The female places the male’s milt in the mouth, and then pours the previously cleaned surface with them, while sticking eggs to it.
Thus fertilization of the eggs is almost 100%. Most often, caviar is deposited on the leaves of plants.
spawning of otsinklyusov
The performance of the female is 80-130 eggs.
After spawning, the adults fish out, the temperature in the spawning ground rises by 1-2 ° C.
Caviar often suffers from mold fungi. To avoid the death of eggs, methylene blue is dissolved in water.
The color of the water should get a light blue tint.
Incubation lasts from 2 to 5 days. Fry can eat even after three days.
Feeding begins with micro-feed and small zooplankton.
They become sexually mature by 7-8 months.
Lifespan Mottled Otozinclus (Otocinclus flexilis) 5 years.
