Pelvicachromis signatus

We recently received this beautiful dwarf cichlid from Guinea. The species is a close relative of P. humilis and was known in the hobby as P. sp. "Bandi 1" before its scientific description.

Maximum size in males is around 10 cm, females stay always smaller. As in almost all Pelvicachromis there is an extreme sexual dichromatism. Persons that are not educated in the hobby can easily think that males and females belong to different species. The spot on the belly of the females looks incredibly; there is already a saying in our fishhouse that

 goes like this: "who has put the lamp inside the belly of this fish?"

These fish originate from forest creeks and should be kept at comparatively low temperatures, around 22 to 24°C, and soft and slightly (!) acidic water. It is important to offer the fish sand as gravel, for they love to dig.

For our customers: the fish have code 560454 on our stocklist. Please note that we exclusively supply the wholesale trade.

Lexicon: Pelvicachromis: the Latin word pelvis means "pelvis"; chromis is another genus of perch; the generic name refers to the coloration of the belly. signatus: Latin, means "signed". humilis: Latin, means "depressed".  Suggestion of a common name: Bandi dwarf cichlid

From Peru we received once more juveniles of the fantastic predatory catfish B. juruense. Adults of this species attain a maximum length of around 60 cm and have a very nice, zebra-like striped pattern. The coloration of the body of the juveniles is very variable. There do exist spotted ones, striped ones or even uniformly dark ones. 

All have in common the large, white caudal fin. On the upper lobe of the caudal fin is a filament that is as long as the body of the fish. Juveniles - the photographed specimens are 5-8 cm long - are already predators. Sometimes they swim free in the water column, the head turned upside, against the current. Now the caudal filament works as a stabilizer, 

comparable to the tail of a kite. Another, species-specific behaviour of the fish is to sit on the bottom, braced on the ventral fins and looking against the water surface. It seems likely that in this position the long tail filament works as a fishing rod that attracts small fish.

For our customers: the fish have code 211200 (5-8 cm) and 211201 (7-10 cm) on our stocklist. Please note that we exclusively supply the wholesale trade.  Lexicon: Brachyplatystoma: from ancient Greek, means "short Platystoma"; Platystoma is another genus of catfish. juruense: after the Rio Jurua, the type locality.
