Good afternoon, dear colleagues! We continue to get acquainted with interesting aquarium fish and on the agenda today we have the Panamanian Sturisom.
This aquatic animal belongs to the family of chain catfish or loricaride. In nature, the fish is found in the waters of Panama and Colombia.
Sturisom prefers reservoirs where there is a flow of water.
Sturisom Panama has a long and low body. Below it is flattened and at the end there is a very long tail stem.
On the face of the fish there is a small growth. The fins are quite large, and the end of the spinal has a crescent shape.
The blades of the caudal fin are fork-shaped and the ends are filiform. The color of the body and fins is reddish yellow. Along the whole body of the fish, there is an expanding dark brown strip, which smoothly passes to the dorsal fin.
At the base of the dorsal fin, the stripe begins to split apart.
The abdomen is silvery-white and has a scattering of yellow-brown spots. On the rays of fins, there are also dark brown spots.
The female has a paler color, and the first rays of the dorsal fin have an ocher hue. All other fins are whitish-gray. Before spawning, the female’s abdomen arches strongly.
If you look at the sturysum from above, the females head is narrower, and it has a wedge-shaped shape. Before spawning, the male has long, dense setae, or odontodes.
In young males, these setae are small (up to 1 mm in length). The maximum body length of the fish is 18-20 centimeters.
Sturisom Panama is a peaceful aquarium fish, which calmly relaxes on stones or snags during the daytime. The activity of the fish begins to show at twilight time of the day. It is best to have a flock of stais in a species aquarium with a capacity of 150 liters or more.
But they can also be kept with medium peaceful aquarium fish that keep near the upper layers of water (pearl gourami, marble, chocolate, lyalius and other labyrinth ones).
The aquarium should have dense vegetation, snags, flat stones. The temperature of the aquarium water should be in the range of 24 – 28 degrees, the acidity of 6.5 – 7.2 pH and hardness from 4 to 10.
Every week it is necessary to substitute ¼ – 1/5 of the water for fresh. In addition, a sufficiently strong flow of water must be present in the aquarium, which can be obtained thanks to a good mechanical-biological filter. 70% of the diet of fish is food of plant origin (peas, lettuce and spinach).
In addition, the diet can be varied flaky and pelleted feed. In the aquarium it is necessary to maintain cleanliness and order, the soil and water must be clean.
Do not overfeed the fish, because all the remaining and not eaten food will rot at the bottom and pollute the aquarium water, and this Panamanian sturice tolerates.
The fish reaches sexual maturity in about one and a half to two years of life. The finished pair for spawning begins to clear the space for future laying. This may be a large flat stone, snag or glass aquarium.
Place under laying should be well purged with oxygen and water flow. The female spawn lays in portions, which are immediately fertilized by the male.
When all the eggs are in the nest, the female sails away from him and provides the opportunity for the offspring of the male. He stands above the clutch and directs the stream of water to the clutch by waving it with its fins. The incubation period of caviar is from 5 to 7 days.
When the larvae hatch from the eggs, the male stops caring for the offspring. If you take a glass tube with a sealed end, all the larvae can be transferred to another aquarium with the same water parameters as spawning.
After a couple of days, the larvae turn into fry and they are ready to feed on scalded and ground nettle leaves, cabbage, dandelion.
