Hello Fredrik.
Welcome to the Homepage and to the Project, – I am very glad to have someone else in Scandinavia 🙂 (I live in Copenhagen)
My opinion on the photos you have uploaded are
Picture 1 – yes, resembles nagyi
Pictures 2,3,4,5 – they are linkei for sure, – but ‘moon spot’ ?? 🙂 .. I am sure its just a ‘shop fancy sales name’, – the blue spot is normal for linkei.
The last one, – p. gunawani ?
This I couldnt tell for sure, I guess the chance is really small. We will need someone else to look at the pictures, probably Peter Finke is best for this.
The fish at the photo is rather short in the body, – which is a little different from most of the species we see as sp.bintan, blue line etc.
Where did you buy them ? Imagezoo ?
(ps. and according to our ‘security’measures all first posts of new users has to be approved first, this is why you didnt see your post before now)
