Consider floating fish in the aquarium. What is the body shape of fish? Is the body of the fish uniformly colored? Is the side line visible? What is the location of the mouth? Are there scales? Note the location of paired and unpaired fins; on the nature of the movement of the fins when the fish is standing still; when it moves; synchronous movement of the mouth and gill covers; is there a connection between them; what is the attitude of individuals of different species to a sharp wave of the hand at the glass, knocking on the glass; what are the nature and speed of movement of fish at the moment of fright ..

1) The shape of the body is elongated and flattened from the sides.
2) males – the color is not uniform with a gradient brightness in the tail area, which gradually increases there (bright orange, if in principle). The body itself is gray, with specks of black.
Females are a nondescript uniform gray color, which ends on the tail and smoothly flows into a similar black with blue pigment inserts.
3) my pets do not have a pronounced lateral line as such. rather not visible.
4) my fish have a mouth rather located at the top, there are scales.
5) Males have long fins, there is a gonopodium – an anal fin that has turned into an organ of fertilization. The female has smaller fins and a tail
6) Character:
when standing, the fins do not move much. not counting the tail. , pectorals are slightly elevated.
when it moves, it actively uses the tail, pectoral and dorsal fins.
7) Certainly exists: when the fish swallows a portion of water through the mouth, the gill covers are closed, then the fish closes the mouth, a portion of water is driven through the gills and removed through the gill covers. The fish then swallows the next portion of water.
8) reaction of males: sounds quickly float away from the source when lightly hitting the glass with their fingers and hurries to lie down on the bottom. He is calm about waving his hands, even having an interest in movements, involuntarily repeating them with his tail.
Females are the opposite, only the reaction to hand waving is the same.
9) at the moment of fright, both experimental individuals showed themselves actively, quickly fingering their fins and moving the body of the body, hiding at the bottom in coarse soil. In fry, the reaction is much faster.
