Aterina Ladigezi, Sunshine or Telmatherin Ladigez is a small but spectacular fish with an attractive color, called the “sunbeam” for the unusual structure of its fins.
Sulawesi Island (formerly known as Celebes), Indonesia, located in the southeastern part of the Asian continent.
It lives in clean, slowly flowing waters around the foothills and in the mouths of rivers.
High elongated body slightly compressed from the sides. There are two dorsal fins.
The mouth is small and raised up.
The color is translucent, yellowish-olive, on the sides bluish shiny scales. From the middle of the body begins a green-blue shiny strip that reaches the caudal fin.
The anal and second dorsal fins are yellow, and the elongated rays on them are black. At the top and bottom of the caudal fin are two dark longitudinal stripes with a yellowish edging along the edge.
In nature it grows up to 8 cm, in an aquarium it is no more than 6 cm.
For the maintenance of a group of fish an aquarium of 60 cm in length and with a capacity of 60 liters and more is required
Plants are needed in limited quantities, as the fish love free space to swim. The growth of floating plants should be limited to a special contour.
Dark fine-grained soil will emphasize an unusual color.
Like some other rainbow fish, they can be quite shy and will be much better if they are kept in a group of at least 6-8, preferably more. Males will look much brighter in the company of rivals.
Try to keep 2-3 females per male.
Temperature: 22 – 28 ° C;
pH: 7.0 – 8.0;
Stiffness: 10-30 ° DH.
Contrary to popular belief, they do not require the addition of salt to their water, although they can tolerate moderately brackish water. Tolerate lowering the temperature to 20 ° C.
Fish do not tolerate contaminated water, so filtration with aeration is necessary, and water changes should be carried out as often as possible.
Peaceful disposition allows you to keep with all non-aggressive types of aquarium fish, but against the background of the refined grace and beauty of the sunbeam, others may look a little rough.
In food unpretentious and take live, vegetable and dry food. The main thing is that they all be small enough.
They like to catch small insects near the surface, but they also enjoy eating daphnia, a pipe maker, mosquitoes and Cyclops larvae. Pick up food at the surface, on the bottom behind it almost never sink.
In males, brighter and larger, the backward curved and elongated rays of the anal and second dorsal fins give the impression of separate rays.
Sexual maturity reaches about 8 months.
The volume of spawning aquarium – from 50 liters. The soil is not needed, and small-leaved plants and richia are needed.
The maximum water level is 20 cm.
Water parameters: 25-28 ° С, pH 7.2-8, dН 11-20.
Before spawning, the producers sit for a week and the readiness for spawning is noticeable along the rounded belly of the female and an increase in the number of fights between males.
Spawning group – for 2-3 females 1 male. In the spawning can be planted 2-3 groups.
Sun rays spawn every day for several weeks. Meals during this period should be two meals a day and consist of live food.
After a week, a maximum of one and a half adults settle out either to the general aquarium, where they will continue to spawn and then they will have to catch the spawn, or to another spawning ground. This is necessary, since the fry gathering from the surface begin to hatch from the spawn of the first spawning ground. A day later, the young are already able to swim.
Fry large enough, but grow slowly. Infusoria, rotifers and nauplii of Artemia are suitable as starter feed.
