White Saum - rivulatus or stalsbergi?

[Aqualoon]

Have owned plenty of both in the past, looks like a Rivulatus to me.

Rivulatus, no doubt - looks just like my male, this is from several months ago, he has grown quite a biit and developed a much more pronounced nuchal hump since these were taken

Here's some georegous silver saum from a hobbiest breeder in Australia. Silver saum son and orange finned dad. They are unfortunately hard to find
