At some point I had these fish – shown in the picture – they were id’ed as p.sintang / sintangensis ? –
I remember I had to buy many fish because most of them were males as well.
They were actually then one of the species which did not prove so difficult to breed, – but here again most were males.
I kept them as in my other tanks, at that time though I was not very good at keeping the ph low, so it was around 7-7.5
