Hello Omaha.
That a beautiful photo of your fish. I have got a reply to your post from Peter, who at the moment is in Poland, and has send the message from his telephone, – I will post here what he says :
I read this in Eastern Poland and can respond shortly only via mobile phone.
1. Sentang: There are good Pictures by “Big Tom” in our Forum. Perhaps Helene could help. Your fish are no Sentang, that species is the most traded P. In Recent years but Looks rather dull.
2. Harveyi: your fish are no harveyi as Martin said already. The ventrals are false and the Black band at the end of the caudal is Not broad enough.
3. Your fish are probably the so-called “blue line”. This Name Shows the stupidity of the Commercial Traders and they Sell different fish from Sumatra with this Name. You habe Been lucky for yours are beautiful.
Please excuse the mistakes in.my messsage, they are due to that silly technique of my mobile phone.
