The chocolate gourami (Sphaerichthys osphromenoides) still belongs to the legendary ornamental fish species. Although the species is common in the wild and other fish of the same habitat (e.g. harlequin barbs) do not cause significant problems in the aquarium, it is a gamble whether chocolate gouramis will do well there. Possibly this is related to the fact that there are several, very similar species and that they have different sensitivities – at least this is what some observations and field collections indicate.
Additionally, all chocolate gouramis are extremely susceptible to infectious diseases of all kinds and tolerate medications poorly – an unfavorable combination!
We currently have chocolate gouramis in stock from Jambi Province on Sumatra. Many specimens from this population stand out with an attractively marked anal fin. Another peculiarity of these fish is that there are often specimens with Piebald markings. This refers to animals in which pigmentless (i.e. white), irregular spots appear. At first sight this seems frightening, because bacterial infections and also other diseases look quite similar. However, treatment is not necessary, and may even be harmful. We observe this phenomenon with the animals of Jambi from time to time, first we noticed it in 2007. We bred these fish once as a test, the photo of the breeding female is from this time.

From Indonesia we received beautiful, very large and strong chocolate Guramis (Sphaerichthys osphromenoides). Unfortunately the exact place of origin is not known, but we suspect that they come from the Indonesian part of Central Borneo, Kalimantan. Particularly noticeable in the animals is their high red portion in the coloration, which is however somewhat different with each specimen.

Sphaerichthys osphromenoides is the most famous representative of the in southeast Asia indigenous chocolate gouramis. Like other chocolate gouramis Sphaerichthys osphromenoides is a delicate and at least while settling down a sensitive fish.
It’s natural biotope are shore areas of small, still and slow-moving black water on the Malayan peninsula and Sumatra. As a typical black water fish it needs a acidic, soft water. Because the natural habitat of extreme black water fish is very pour of bacteria the adaptability to the high bacteria density in the aquarium is very low.
Flakes are mostly not accepted and a feeding with live or frosted brine shrimp, mosquito larvae or fruit flies is indispensable. For the breeding the water-quality again needs to be inceased , but should succeed with a little luck. Interesting is the several weeks lasting mouth-broodcare. The chocolate gourami is no fish for beginners and it should only be fall into the hands of experienced hobbyist.

Finally we can offer again the most beautiful species of Chocolate Gourami: Sphaerichtys vaillanti. The species originates from the Kapuas basin in the Indonesian part of the island of Borneo. S. vaillanti is not only the most beautiful, but also the hardiest species of all Chocolate Gouramis. However, it is nevertheless by no means an easy to keep fish. One will have only success with this fish when the natural habitat – very soft, acidic blackwater and lots of dead leafes on the bottom – is imitated and preferably life food is given. Most hobbyists underestimate the intraspecific aggession shown in all species of Chocolate Gouramis. Most problems with diseases in Sphaerichthys result from distress based on mobbing.
The males in Sphaerichthys vaillanti are much duller in respect of coloration than the tigered females. The males have also the job to care for the spawn – they are mouthbrooders. In neutral mood the males look much alike the Crossband Chocolate Gourami (Sphaerichtys selatanensis), but S. vaillanti can always be recognized by the sharp head.

The Golden Chocolate Gourami may be the least attractive of all Chocolate Gouramis in respect of coloration, but it is nevertheless a very interesting species. The fish is the rarest of all Chocolate Gouramis as well in the hobby as in the wild. So we are very glad in case we are able to offer it.
The species is a mouthbrooder, the male cares for the eggs. Females develope a dark spot behind the head during displaying and can be also recognized by the vertical stripes over the yellowish belly. Males, on the other hand, can show a hoizontal stripe on the body.
In contrast to the other species of chocolate gourami, Sphaerichthys acrostoma seems to be rather peaceful against conspecifics; at least they can be often observed swimming around in small groups. This species attains a maximum length of about 5 cm.
