Mogurnda mogurnda

30. October 2009

The the Northern trout gudgeon is one of the very few aquarium fishes from Australia that became popular before the 1950ies. They are attractively coloured and they can be bred quite easily in contrast to most other gobies.

Sadly this gudgeon is quite quarrelsome if kept in wrong community and so the species disappeared more or less. But a number of breeders still has it and so we are glad to be able to stock Mogurnda mogurnda again.

It is not sure that the species´ name is correctly applied, because a number of very similar species exists and even specialized scientists are not able to tell them apart without genetic methods or the detailed place of origin.

Mogurnda are free swimming gobies and so their territory is not build up on the bottom like in most other gobies, but in the whole water column. The tank must be rich of hiding places and furnished a bit unclear in order to enable the fish not to look at each other the whole time through. Perfect tankmates are rainbowfishes, larger barbs and danios, and also robust tetras.

Trout gudgeons feed on meet only and ignore any plant material. They do not spawn in caves, but are open brooders that attach the eggs on stones, roots, broad leaves etc.. Males guard the eggs until they hatch. Sexes can be best distinguished by the shape of the genital papilla, which is narrow and acute in males and broad and blunt in females. The shape of the head is also a good indication, for males develope a typical humpy head.

The water for Trout gudgeons can be soft or hard, the pH should be around 7, temperature between 22 and 28°C. Maximum length is given with 17 cm in literature, but most specimens stay much smaller and usually they reach only 10 cm. The species is sexually ripe at a length of around 6 cm.

For our customers: the fish has code 436402 on our stocklist. Please note that we exclusively supply the wholesale market.
