This wild collected specimen from Peru has a very unique colour aberration. Usually
such specimens cannot survive in the wild, but this fish is a healthy, adult animal.

For our customers: the fish has code 257924 on our stocklist. Please note that we
exclusively supply the wholesale trade.

Lexicon: Hemiloricaria: ancient Greek, means "half loricaria"; loricaria is another
genus of catfish.

Ernstichthys megistus

For the first time we were able to import a very astonishing species of catfish,
which was known until 1985 from 3 specimens only. At the first glimpse the small
animals - they are hardly 2 cm long - remind one on the Asian catfishes of the genus
Akysis. Actually they are relatives of the banjo cats.

The reason why this and some close relatives, which are classified as tribe
Hoplomyzontini, are so little known lies probably in their way of life.
Hoplomyzontini seem to settle on the bottom of relatively fast running waters where
they burry themselves in the ground. As most of them are very small fishes they are
hardly ever collected by usual catching methods.

Our specimens show a wide range of coloration, the extremes are grey ones and yellow
ones. It is unknown wether this represents sexual differences.

Athough our specimens proofed so far to be quite hardy, it seems necessary to provide
fine sand for them, which they use to burry themselves. The type specimen of
Ernstichthys megistus was collected in Ecuador and is around 7 cm long (standard
length without caudal fin). This is by far the largest size of any Hoplomyzontini
known so far, which usually hardly reach half that size. Also the other known stored
museum specimens of E. megistus, which originate from Peru, are much smaller (about 3
cm). Ernstichthys megistus is a fish we have much to learn about and aquaristis can
help with their observations to understand the life history of that fascinating
creature.

Lexicon: Ernstichthys: dedication name, means "Fish of Ernst"; A. Ernst worked at the
Universidade Central de Venezuela. megistus: probably latinized form of the ancient
Greek word megistos, which means "the greatest".

Moema cf. ortegai

We were able to import astonishing large Moema cf. oetrgai from Peru. The females are
around 8 cm, the males around 12 cm long. This places them among the largest species
of killifish known so far. The extremely large pectoral fins of the males are very
impressive. However, the whole finneage of the males is much enlarged and some fancy
bettas and fancy guppys must shame on them when looking at the Moema. The only
difference is that in this case not the human breeder but mother nature selected for
enlarged finneage.

Moema are bottom divers, this means the spawning pair dives deep in the bottom, where
the eggs  dwell during the dry season. The adults must die then and thus never become
old in the wild, but in captivity the can live much longer. The eggs need 5-10 months
to hatch.
