I have a few years of experience with Ruinemans, and I can say they have no idea what they’re selling. The picture on their site shows Nanochromis transvestitus, and I wouldn’t be surprised if that is actually what you get. I ordered some through my LFS though, so they should appear at Utaka in Amersfoort in a few weeks, when Ruinemans’ summer break ends.
Since P. tweediei‘s geographical distribution is fairly limited, it could as well be harveyi or [/i]alfredi[/i], which would’nt be bad either.
They have P. linkei too. Quite big already and in very good condition.
