![]() Hemigrammopetersius caudalis, (Boulenger, 1899) Yellow Congo Tetra Origin: Stanley Pool, Congo, and tributaries. Here the fish occur in open water, predominantly in forest rivers. Etymology: unk Synonyms: Petersius caudalis, Alestopetersius caudalis First European import: 1954 Description: See pictures Care: This congo tetra remains slightly smaller than it's cousin, and is also somewhat more delicate. They are best kept in schools of 6 or more fish in larger tanks of 1 meter. As the fish are shy, they do best in a well planted tank, especially floating plants are recommended. Frequent waterchanges and well filtered water are beneficial. The fish do well in neutral water, and are pretty indifferent to hardness. Hemigrammopetersius caudalis is a peaceful fish, that doesn't touch the plants, but needs a lot of free swimming space Temperature:22-25°C Feeding:Omnivorous Size:Up to 7 cm pH: 6.5-7.0 Breeding: Similar to Phenacogrammus interruptus, although a bit more difficult and less productive. The hardest thing is to get the females in proper breeding condition, which is mainly depending on a varied diet. Frequently feeding the breeding pair with flies, dragonflies and other insects is sometimes the key to a succesfull breeding attempt. A large breeding tank, 80 cm, sunny location, lowered waterlevel, and protection for the eggs are necessary. Soft, slightly acidic water is best. Sexual dimorphism: Males have an elongated dorsal fin, and white tips in the fins. Prices:4-6€ Additional: Seldom available Picture references: All pictures E. Naus References:Baensch, H.
