Origin from Carinotetraodon travancoricus

Wasserkarte-Kerala-Indien Provinz-Kerala-in-Indien Unfortunately, I never been to India and so I based my information on scientific literature references. As a scientifically valid sources are kown the Pamba-River, Vembanad lake, Minachil-River, Shertallai, wetlands around Thrissur and the Chalakkudy-River in Kerala province in the south-western of India. The province provide 44 infiltrating major rivers and 29 lakes. Only the Vembanad lake is 83 km long. About Kerala I just can recommend Wikipedia.

This hugh area is also called Backwaters. Besides the pure freshwater lakes and Rivers, this area also contains salted channels. Even in the late nineteenth century, the Vembanad lake was originally connected with the Indian Ocean and thus under tidal influence. The breeding reports of Frank and Ren demonstrated sucessfully breeding in fresh water. But there are still reports, which advice to add salt into the tank. My personal experience is that the genus Carinotetraodon travancoricus can be maintained well without adding any salt to the Water. An expedition in May 2005, confirms that Carinotetraodon travancoricus is a freshwater Puffer.

Andreas Dammers, had done a discovery in the Forum Indianaquariumhobbyist I would like to mention at this point, that the Indianaquariumhobbyist.com has kindly allowed the publication on this page. In May of 2005, Madan Subramanian and a group of IAH had undertaken a well-documented expedition in Kerbala. The goal of this expedition was a small cichlid Etroplusl, but also to the genus Carinotetraodon travancoricus it was very informative. So we have now the exact position of the environment and exact water parameters and as a gift even photos. Why is an expedition to search for other fish was so interesting? Because of this report and photos can be assumed that the two genuses Etroplus Canarensis and Carinotetraodon travancoricus are sharing the same habitat, at least in one location.


Starting point for the expedition, this bridge. It is a few kilometers off Subramanya, a small temple town about 60 km from Mangalore, in the Western Ghats.

At the foot of the bridge was the team from IAH directly to the search. Already amazing how the view of an ordinary bridge to a breathtaking panorama changes.

Well, in the right picture, is a middle Etroplus canarensis. This was actually the fish of desire. In addition to the low water level, you can still see the abundant opportunities hideout

And while they were waiting for the small cichlid, suddenly ... in the same location a few seconds later ... a Dwarf Puffer. The first photo from the wilderness

Thanks to the professional approach of IAH-Teams now, we have two locations with the main water parameters, which I summarized in the table. Regarding the total hardness (GH) has assured me that the measured values in American hardness was measured. As a conversion factor of 1dH (German GH) 17.8aH (American GH) would KH and GH because of the water analysis of approximately (1.5-2) degrees of hardness. . In further documentation is also a GH-Wert of 2 spoken.. There is still the possibility of the aH (American hardness) in eH (English hardness) with a conversion factor of 14.3. The results would then about 25% from the dH (German hardness) differ. Whether it is 1.7 or 2.2, the water is very soft.

At the first location, in addition Etroplus canarensis also found the following types: Puntius mahecola Puntius fasciatus Garra mullya Noemacheilus triangularis Danio Retrieved Esomus danricus Parambassis wolffii Carinotetraodon travancoricus harlequin daniconius Barilius gatensis Hypselobarbus jerdoni Hyporhamphus limbatus
At the second location was found beside Etroplus canarensis also found the following types: Puntius mahecola Pristolepis marginata Garra mullya Danio Retrieved Carinotetraodon travancoricus harlequin daniconius Barilius gatensis
All locations were 75-100 kilometers from Mangalore, where the rivers lead into the Indian Ocean . In the areas where they looked for fishes and catched some, the maximum depth of water in the two rivers 1.2 meters. The temperatures refer to the May 2005. In winter the water temperature will reduce to approximately 25 ° Celsius. This results in a water temperature range from (25-33) ° Celsius.
