To breed Congo Tetra I use water of under 3 � DH, which I filter before use 4 to 5 days over peat. The aquariums must hold at least 50 litres of Water. Phenacogrammus likes to breed on a place if possible with some sunlight. Disturb them during breeding and they will break it off. The Congo Tetra breed over several days, whereby they deliver each time 40 to 60, about two and a half millimetres large eggs. They are clear and possess a clearly recognisable reddish or yellowish core. At a temperature of 24� to 25� C the hatch after six days, at lower temperatures it is somewhat longer. The eggs of the Congo Tetra are quite robust against low temperatures, and withstand cooling down to 20 C without damage; only the producing duration extends at 21� to 22�C to eight days. they neat a somewhat hardier plants. like Fontinalis and Java fern. The best temperature to breed is between 23 and 25�C a higher temperatures slows the fish down. Generally They do not pursue their Eggs, so that one can leave the animals in the breeding Tank during to over 5-6 Day stretching breeding period. Now and then individual Congos will eat the eggs, then one uses a grid of plastic rods or netting which allows the eggs to fall beneath and prevent the parents from following. The question whether a certain kind is an egg eater or not, I can not answer. Since individual pair often to not breed easy, one uses a group of 3 to 5 pair, Thus the fish breed more willingly, but you will have to use a larger aquariums this way.

The hatchet young fish accept immediately fresh hatchet Artemia also dry food of appropriate size. Their raising makes no difficulties. At the beginning they are very fast growing, but only in the second year the offspring become reproductive. The males are larger than the females and possess flag-like extended dorsal fins.

Nematobrycon palmeri.

Emperor tetra this fish is often called a problem fish, what he is not at all, there can be breed quite easy. One takes a pair of emperor tetra one recognises the males by the larger and longer fins and by the more intensive colouring, a 30 cm plastic aquarium for instance l cm high sand layer, a small handful of Java moos, tap water, which I filter over peat for few day. Aquarium, sand and plants are thoroughly cleaned with water, and fish into the Aquarium, and not forget a cover. The emperor breed mostly the next day, and have to be taken out of the tank after breeding. After approximately 30 hours with a temperature of 24� C the young fish hatch. We feed immediately after free swimming with fine food such as fresh hatchet Brine Shrimp, Paramecium and try food. The fishes are not very productive, but we can set them up again after 8 days to be breed.
