Gold forms – also called xanthorists – are quite common in fish, even in nature. Ever since the beginning of man’s records of natural phenomena, there has been talk of golden perch, carp, crucian carp, tench and pike. Of course, such mutations occur much more often in breeding than in the wild, because there such strikingly colored animals soon become victims of predators.
In the case of the Pearl Gourami (Trichogaster leerii, sometimes also called Trichopodus l.) a gold form has only been known for a comparatively short time. It is difficult to say whether this will become established on the market or remain a rarity. But compared to the first specimens we received in 2015 (see https://www.aquariumglaser.de/en/fish-archives/trichogaster_leerii_gold_en/ the animals we can offer now are much stronger.
Besides the orange colored breeding form of this gourami from Burma (see https://www.aquariumglaser.de/en/fish-archives/colisa-labiosa-orange-2/) there is also a very attractive, deep red colored breeding form. In order to keep these wonderful animals in their bright coloration permanently, it is necessary to provide certain types of food (e.g. Cyclops, Spirulina or also special flake food). Without the natural substance astaxathin contained in it, the colors will otherwise fade in the long term, just as in the case of flamingos, whose red coloration is based on the same substance. In addition to its positive effect on coloration, astaxanthin is also very healthy, as it is a natural antioxidant that reduces inflammatory processes. In human nutrition, astaxanthin is considered a dietary supplement.
But back to the Colisa! They are very beautiful and peaceful gourami, perfect for well-maintained community tanks with rich plant growth and also peaceful by-fish.

The pearl gourami (Trichogaster leerii, Trichopodus leerii) is one of the most popular aquarium fishes at all. It is probably not exaggerated if one assumes millions of individuals in aquariums all over the world. All these fish are bred ones. It is only little known that the pearl gourami belongs to the endangered species as a black water inhabitant in the wild, because the habitat is dwindling more and more. We have already succeeded in importing animals from southern Thailand (https://www.aquariumglaser.de/fischarchiv/trichogaster-leerii-wild/) and from Sumatra (Jambi), now also from Borneo.
We very much hope that interested enthusiasts will succeed in building up strains of this wonderful animal of known origin by the occasional import (a threat to the free-living stocks by such removals is excluded from a scientific point of view). This would be an active contribution to the protection of species. Already frequently, species or populations of small fishes could be saved from extinction by such hobbyist—based breedings. However, a possible return to nature may only be attempted with animals whose original origin is known.

The Pearl Gourami (Trichogaster leerii) is an absolute classic among the ornamental fish. The species is always available in the petshops all over the world and they are usually quite cheap. These traded fish are bred ones. Wild collected ones are hardly ever offered; the species is endangered in the wild, because the habitats become destroyed in a very great amount. Sadly the quality of the bred fish sometimes is not as good as it should be. This is due to the low price the breeders get for the animals. But currently we have obtained wonderful, fully coloured specimens from a local breeder.

The dwarf gourami is the perfect ornamental fish. It unites magnificent coloration, a peaceful mind and an interesting behaviour. It becomes only 3 cm (wild caughts) or 6 cm (artifical bred sports) long and due to its calm habit it can be kept even in smaller tanks. And if it comes to feeding: the dwarf gourami happily accepts any type of fish food, may it be dried, frozen or alive. The only condition: food particles must not be too big, because the dwarf gourami has a tight throad. Sometimes the dwarf gourami is named Trichogaster lalius, but this is an opinion we do not follow.

For the first time we obtained wild collected pearl gourami from Thailand. This is worth mentioning for several reasons. First, it is very ambigously discussed in the scientific literature wether the species occurs in Thailand at all; twice: the wild populations of the pearl gourami are declining terryfing fast, for the species is strictly adopted to blackwater (collecting the fish for or the trade has no impact on natural populations); and finally we have even good informations where the fish were collected. They originate from Narathiwat province near the city of Su-Magi Kolok. At this place usually the glass catfish (Kryptopterus vitreolus) is collected.
Initially the new arrivals looked very similar to their bred cousins. But a closer look showed an interesting difference: in the wild females the back has almost not pearl-spots! Currently the fish are something larger than half-grown (6-8 cm).
