Tropical marine fish
Fish stumps are found in coastal caves of slowly flowing waters of the North-Eastern part of South America on the island of Trinidad. In Europe, the fish-stump was first introduced in 1907. Russia was known before the war in 1941. Under natural conditions males reach 10 cm in aquariums usually up to 7 cm Females are smaller than males.
Strongly laterally compressed body with a high fish-chopping ellipsoidal shape. The head is very big. Interesting shape of the fins. Dorsal and anal composed of two parts: front long, back arched and much higher, extending back at an angle of about 45°. The pectoral fins have the form of a strongly elongated triangle with a flat on the end, consisting of the beam. They are usually directed vertically downward. Pelvic fins greatly elongated. Dorsal and anal well developed. The body is colored yellowish-brown color with black and bluish speckles, during the spawning season, turning almost black. The body obliquely pass four dark transverse bands of the same color arranged on them even more dark dots. On the operculum there are three dark spots with light border.
His Russian name of the fish-stump was due to a peculiar coloring. Along with dark-colored body they have a completely transparent tail fin and rear part of dorsal and anal, potomarina seems chopped off. The pectoral fins are colorless too. The female is less brightly coloured, the body is slightly lower during the breeding season she has a short ovipositor.
Conditions are the same as for the whole family. Stumps are aggressive against members of both his and other species, they can swallow a fish that reached a third of the size of their own body, so they can contain only together with representatives of their own species or with other larger species (see video below).
Fish-stump sensitive to temperature fluctuations and changing water, especially tap, and they can’t stand the presence in water of various chemicals. The optimal water temperature when the content of 22-26° C, minimum 20°, at a dilution of 28-30°.
Females lay eggs in caves or on the reverse side of wide sheet (typically in the spawning area placed flower pots of suitable sizes). Immediately after spawning the female should be planted. The male removed after 2-3 days after hatching. The larvae initially are attached by means of mucous threads to the plants or to the pot, then fall to the bottom. In food the fry need only on the eighth day. The feeding is simple, the first time the fry are fed infusoria and rotifers.
Young fish stumps are light yellowish-brown color with Golden sheen, with scattered throughout the body spots and periodically intermittent oblique stripes. Usually fish kept alone, hiding somewhere under leaves or other cover.
