Gobio gobio, gudgeon

7. May 2020

The gudgeon, Gobio gobio, is one of the smallest native fish. It usually grows to 8-12 cm, rarely over 15 cm long. The record is said to be 21 cm, but such giants are as rare as people over 2.20 m long. Because of its small size and pretty colouring (compared to the mostly silvery other native species) it has been kept in aquariums since the beginning of aquarium science, where it thrives very well. The water temperature can be in the range of 15-25°C, which can be easily realized in living rooms even today, avoiding long lasting temperatures above 22°C and aiming for a cool hibernation at around 8°C and 6-8 hours of light.

The gudgeon is a bottom fish that likes to swim in a troop with its own kind and is completely peaceful against other fish. It needs open bottom areas of sand and gravel where it looks for its food, which consists of small animals of all kinds (in the aquarium any usual fish food that sinks to the bottom). Vegetable food does not play a big role and is rather accidentally included. In nature, gudgeons are mainly found in clear, often flowing water. The aquarium should therefore be well maintained and have only a little mulm on the bottom.

The gudgeon is only suitable for the garden pond if it fulfils its requirements for clear, clean water and free ground surfaces with sand and gravel. The gudgeon cannot live in fully grown swamp ponds.

Gudgeons spawn in gravel; they do not care for their brood.

Goldfish Oranda 2-3 Colour

23. April 2018

In the minds of many keepers the goldfish is a coldwater fish and has its high season in spring time, when the garden pond season starts. This is of course true, but reflects only a part of the reality. The highly developed sports – like the orandas – often are better kept in aquaria than in outdoor ponds. The optimal water temperature for these fish is between 14 and 28°C.

Currently we received very nice Oranda 2-3 Colour that were bred in Singapore. These animals are colored individually very different and in all probability they will also change some of their colours during their individual lifetime, which can be as long as 30 years.

The ideal home for such fish is a large tank with soft sand and only a mild current. Goldfish are social animals and absolutely peaceful against all tankmates. One must only take care that no other fish takes the long fins of the orandas as toys and thus jars on the nerves of the poor goldfish permanently. By the way: all goldfish – and so also all orandas – are a perfect weapon against duckweed. No plague of duckweed will ever appear in a goldfish tank, for duckweed is one of the favourite dishes of goldfish.
