Geophagus steindachneri

2. December 2022

The redhump eartheater (Geophagus steindachneri) from Colombia has had a regular place in the aquarium since it was first imported to Germany in 1972. There are numerous reasons for this. First of all it is very attractively colored. The males develop a red colored forehead hump, which varies very much in size. Over all: the size. In fact, G. steindachneri can grow up to 25 cm long! But sexual maturity starts already with 6 -7 cm length. 

Geophagus steindachneri is considered to be the most specialized mouthbrooder of South America, because the eggs are taken into the maternal mouth immediately after spawning. Instead of egg spots in the anal fin, as found in many African mouthbrooding cichlids, G. steindachneri have orange spots in the corners of the mouth, which achieved the same effect.

We have at the moment nice offsprings of the species in the stock, where the males have as a special feature green-golden areas in the area of the gill covers.

For our customers: the animals have code 678212 on our stocklist. Please note that we supply exclusively to wholesalers.

Gnathocharax steindachneri

15. November 2019

In the natural habitat of the cardinal tetra food sources are very scarce. So it is really astonishing how many species can exist there. However, many of them stay very small. Good luck for the aquarium hobby, for they all make very good ornamental species!

Even a predatory species of that biotope is such a dwarf: Gnathocharax steindachneri. It attains a maximum length of only 5 cm and belongs to the closer relationship to the freshwater barracudas (Acestrorhynchus), what is clearly visibly by the structure of the fangs and teeth. However, Gnathocharax is not dangerous for other fishes larger than approx. 1 cm. Most probably the species feeds on fish and insect larvae in the wild.

Currently we were able once more to import this most interesting, sadly only rarely offered species of tetra. It is perfectly suitable for community tanks with cardinals and other tetras. Here Gnathocharax loves to swim along with conspecifics in the upper third of the water column. The fish feed readily on any type of usual fish food, even dry food is taken from the very first day on, despite the specialized dentition.

For our customers: the fish have code 254653 on our stocklist. Please note that we exclusively supply the wholesale trade.
