[Peter Finke]

So-called “deissneri” could be everything; we had imports that were factually Pseudosphromenus.
Mostly these fish are not interesting, bintan-variants. A stock of spec. Sentang at German company of Glaser’s consisted of 98% males!
Better concentrate on fish that you can buy directly from experienced breeders, if it is not a clear exception (which is possible, of course).
Again, the true deissneri lives endemically on Bangka only and was never imported by the trade. The trade is not active on Bangka. All our deissneris formerly were caught privately. But the stock is lost now. Only a private trip to Bangka could renew it.
