The fish on that bad picture are no gunawani. I bred the only certain fish of this new species whch I received from Horst’s (Linke) private import, still called “spec. Danau Rasau”. They were conspicuous, far more than most other bintan-like forms frum northern Sumatra.
It’s a well known method of the fish-trade that they take an interesting name especially of a new species to get their fish in the market. Themselves, they are unable to distinguish the Paro-forms properly. The old tactics, to call all of them “deissneri”, does not work any longer. People are better informed now and know that this name was wrong in each of the many cases. So, the newest name is the most interesting one that guarantees the fish being bought.
Traders in south east Asia sometime get huge quantities of one species from one or several catching places when the catchers go there some moths after the spawning period. One thousand is not rarely the number, sometimes more, often less. To get these “difficult” fish sold is really no an easy task. An interesting new name helps.
