Nannostomus eques Peru

24. October 2022

The tetras of the genus Nannostomus, called pencil fish because of their somewhat stiff swimming style reminiscent of traveling zeppelins, have been among the most popular ornamental fish for decades. They are very beautiful, usually peaceful and remain small. Three species swim at an angle with their heads up: Nannostomus eques, N. britzkii and N. unifasciatus. While N. britzkii has never been imported in numbers, the other two are commonplace in the ornamental fish market. They are extremely widespread (Brazil, Colombia, Venezuela, Ecuador, Peru, Guyana states) and occur in large numbers. However, there are distinct color differences locally. The variant of N. eques from Peru, which we present here, differs clearly by the coloration of the anal and caudal fin from the conspecifics exported from Brazil (Rio Negro drainage) (see https://www.aquariumglaser.de/en/fish-archives/nannostomus-eques-and-n-unifasciatus-two-odd-birds/).

Nannostomus eques is a very peaceful species, which is always a real eye-catcher due to its unusual swimming style. You should always keep these fish in a group of 10-20 specimens, because they are very social and always stay close to conspecifics in the aquarium.

Coryoras eques

7. October 2021

From the Brazilian state of Amazonas, more precisely from the surroundings of the city of Anori, we once again received a good number of a beautiful armored catfish, which is known to science for a long time, but rarely appears aquaristically: Corydoras eques. 

This typical schooling Corydoras looks most attractive when kept in black water. The bright orange neck banding undoubtedly serves to keep the swarm together when underwater visibility is poor. C. eques becomes about 6 cm long.

Hyphessobrycon eques “Longfin”

28. June 2021

The Serpa Tetra, also called the Callistus Tetra (Hyphessobrycon eques, formerly known as H. callistus or H. serpae), is the little man’s piranha. Just like piranhas, serpa tetras have an irresistible urge to bite the fins of other fish. And they constantly want to test out who is the stronger. This makes many exciting observations in the aquarium, but one thing you hardly ever see is Serpa Tetras with their fins completely intact.

The magnificent coloration and interesting behavior make many aquarists overlook the naughtiness of fin biting since 1924. In the course of time even a veil-finned variety of these up to 4 cm long animals developed. It too always appears somewhat tattered, but this does not detract from their enjoying life and also recognizably causes the fish neither pain nor discomfort.

One must always maintain Serpa Tetras in as large a group as possible of 10, better 20 animals or more, and offer them a richly structured aquarium. Since they originate from southern South America, where it can get quite fresh at certain times of the year, they should not be kept at high temperatures above 24°C all year round. Every now and then a few weeks without heating at 18-20°C will do the animals a lot of good and improve the colors.

Hyphessobrycon eques wild

15. November 2017

The Serpae tetra is one of the most popular tetras at all. This is doubtless due to its intensive red coloration. In respect of the behaviour one cannot trust them too far. They have the nasty tendency to bite off pieces of finnage from other fish, also from conspecifics. 

From a scientific point of view the Serpae tetra is subject of a controversial debate that lasts already for more than 50 years – and still no satisfying solution has been published yet. How many species cover behind the common name of „Serpae tetra“? And what is the correct scientific name for them? So hobbyists interested in tetras will for sure be happy that we were able to import now some wild collected specimens. They originate from the surroundings of the city of Cuiabá in the state of Mato Grosso. Currently these animals are about 3 cm long and thus not fully grown and not full in color yet, but very healthy and lively.

The import happend in July 2017. We kept some specimens in our fishhouse to see what would become of them. They go for sale now, too. The fish became very nice, graceful Serpa tetras. The most remarkable thing is that they are very peaceful against each other. Of course the males display against each other (as it is usual in the tetra family), but they don´t even hurt the finneage of the competitor, as it sadly often happens in aquarium strains.

So hobbyists interested in tetras will for sure be happy that we were able to import now some wild collected specimens. They originate from the surroundings of the city of Cuiabá in the state of Mato Grosso. Currently these animals are about 2 cm long and thus only half grown and not in color yet, but very healthy and lively.
