Rafael, we need no pictures. These fish are certainly not deissneri. P. deissneri has up to now never been traded. Of course, there may be one first, but it is entirely unlikely. There are no commercial fish-cathcers working on the island of Bangka, and deissneri is endemic on Bangka. We must fetch this fine species some day anew from there ourselves. The trade will not do it for us. They will go on to call all Parosphromenus “deissneri” still for years to come …
The greyish colour indicates that the larvae have hatched; they hatch depending on temperature after 24 hours at the latest. Then they look like somewhat longish eggs, but the care of the male indicates that everything is allright. Meanwhile the tails of the lavae must be recognizable and probably have changed the colour to a more blackish appearance.
Non-fertilized eggs soon became stuck with funghi an will be picked out by the caring father fish. This is the reason why he does it and why we are nearly never successful by a full-artificial care without the male fish. This would mean constant supervision by a looking-glass over days and the picking out of the damaged eggs one after one by hand and a pair of tweezers. The male immediately stops caring the eggs or the young if something has went wrong. As long as he does not do this, everything is allright.
