Corydoras serratus


The saddle-nosed Corydoras serratus from the upper Rio Negro in Brazil belongs to the
most wanted species of Corydoras. Due to the fact that the saddle-nosed species of
Corydoras are in general no schooling fish it is not possible to collect larger
numbers of them in an economically senseful way. This and the fact that there were
times in which exorbitant prizes were payed in Japan for this species made them real
rare in the trade for a long time.


Nowadays there are some breeders of this beautiful species and one of them supplies
us with gorgeous bred specimens of Corydoras serratus. It is very interesting that
although the breeder uses only partent fish that fit perfectly to the original
description the offspring differes much individually in respect to coloration. Some
have only a vertical bar under the origin of the dorsal fin instead of the broad
horizontal bar over the back. This phenomenon was also observed in wild collected
specimens, but there was a good deal of uncertainty if not similar, but different
species were involved. Thus once more the aquarium hobbyists were able to answer a
question of ichthology.


For our customers: the animals have code 245682 on our stocklist. Please note that we
exclusively supply the wholesale trade.

Lexicon: Corydoras: from ancient greek, means "with helmet and spear". This refers to
the strong armor and fin spines. serratus: Latin, means "sawed", referring to the
strongly serrated pectoral spine.

Suggestion of a common name: Saddlenosed Goldpatch Cory

Hippichthys penicillus


Currently we were able to import a new species of freshwater pipefish from India:
Hippichthys penicillus. Basically speaking, there are two types of pipefish. First,
the ones that swim free in the water column, imitating  plant material (sticks etc.).
Twice the ones that are bottom-dwellers and crawl like snakes between plants, stones,
roots etc.. The most important aquarium pipe fish of that group is Enneacampus

The species belonging to Hippichthys are in between those extremes. This is also true
for their habitat. They can be found in pure marine, brackish water and pure
freshwater environments. The technical term for that is euryhaline. 

>From an aquarists point of view it is best to keep them in weakly brackish water
(about 3-5 grams salt per litre). The benefit of the salt is that Artemia, they
primary food resource for pipefish kept in aquaria, will stay longer alive; moreover
any potential salt requirement by the pipefish is thus fulfilled. Please use
exclusively salt that is manufactured for reef aquaria!


The males of Hippichthys penicillus can be easily recognized by the prominent fold on
the belly which serves as a brood chamber. Besides this they also differ from the
females in respect of coloration. Males are deep black with silver shining spots,
wheras the females are much duller coloured. The fish become mature at a length of
6-8 cm, but according to literature they may reach a maximum length of 18 cm.

For our customers: the fish have code 421522 on our stocklist. Please note that we
exclusively supply the wholesale trade.

Lexicon: Hippichthys: ancient Greek, means "horse-fish". penicillus: Latin, means
"brush"; this name was given referring to the finray-structures at the end of the
tail. Microphis: ancient Greek, means "little snake". Enneacampus: ancient Greek,
means "with nine coves", probably referring to the cross section. ansorgii:
dedication name.

Suggestion of a common name: Night sky pipefish

Uaru amphiacanthoides "Manacapuru"


Extremely beautiful, fully grown specimens of this amazonian species of cichlid
reached us now from Brazil. Uaru are peaceful fishes that can be best compared with
discus regarding demands on water quality and temperature. However, Uaru are more or
less specialized herbivorous fishes.


For our customers: the fish have code 688517 on our stocklist. Please note that we
exclusively supply the wholesale trade.

Uaru: after a term given by indigenous people to a toad. amphiacanthoides: ancient
Greek, meaning "similiar to an Amphiacanthus": Amph(i)acanthus is another genus of
fish, the name is nowadays regarded as a synonym of Siganus (rabbit fishes).

Common name: Triangle cichlid
