Indian glass catfish (catfish-Ghost)

GLASS CATFISH (Indian glass catfish, Kryptopterus bicirrhis; Cuvier et Valenciennes) — in length reaches 10 cm Its second name — som-Ghost — fish received for the transparency of his body. Visible skeleton and all internal organs. Body strongly elongate and flattened laterally. The dorsal fin is extremely small and is located immediately behind the head; below the head is deeply cut almost to the caudal fin extends continuously oscillating, crystal clear anal fin. In the reflected light of the fish glisten all colors of the rainbow, at the same time, remaining so transparent that through them are visible for the fish items.

In addition to transparency, the glass catfish is distinguished by a long anal fin, a pair of long antennae on the upper jaw, small dorsal fin (from one beam) and the position of the head body to the surface.

Features:

Glass catfish (Kryptopterus bicirrhis Cuvier u. Valenciennes) lives in South-East Asia, the Great Sunda Islands, Java, Sumatra and Borneo.

They always kept in flocks in the middle layers of water. Lonely fish out of the flock can die. The spacious aquarium with an abundance of thick bundles of marsh plants and rhizomes, which provide shelter to fish and scatter light, creating acceptable for fish habitat. In respect of the conditions fish are unpretentious: they don’t matter much,as the composition of water and its temperature. Optimum temperature 22 to 25° C. aeration, filtration, water change. Lesions of the integument in fishes treated with articlenum (70-150 mg/l) within 7-14 days.

Glass catfish should be kept with members of their own species in the aquarium, lighted by weak diffused light, and put only crypts. Glass catfish are exclusively nocturnal. Fish begin to show their activity only in complete darkness that can be detected solely by flashlight, but glass catfish at night move like a bullet (ricochet), all the time lost sight of. Sometimes catfish can detect the reflection from their fins, reflected from the flashlight. During the day the catfish are in place, either in a pack or separately, sometimes even fight: one to push the whole body sideways, like someone who will push aside, or gently wiping each other. In any case, in the light they are almost constantly hanging in the water column at the same place, and always against the current.

Glass catfish are the most peaceful fish, marnee than guppies. For them, it seems that other fish simply do not exist, if only they themselves had not been touched.

The sight “glass” is the same as all night, i.e. very weak. The principal tactile organs, antennae and lateral line (passing to the side or rear bloodworms catfish catches instantly). Antennae – it is also a means of communication, it resembles the ant: when you contact fish hang parallel to each other and within ten seconds there is an intense “dialogue” mustache. And also their place in the flock they take up, first, “greeting” with other catfish mustache, and then type “hold” them for each other.

Reproduction:

Mature in 1.5-2 years. Spawning is seasonal. gregarious, but can be paired in the water column. The productivity of 100-200 eggs. The incubation period is 5-7 days. The cylinder bottom.

Starter feed: rotifers, Cyclops nauplii, mikrokorm.

Feeding:

Favorite food glass catfish — zooplankton and larvae of aquatic insects moving in the middle layers of water. Take food only in the water column and from the surface, and what fell to the bottom, then disappeared. Feed from the bottom of the fish pick up awkwardly, lying on her side. Food can take day, but not very willingly.
