It feels a bit nostalgic as this species is an old favourite of mine and I haven't found them in the trade (here in Sweden) for about 10 years.
They were sold as "Amblydoras affinis" and I suspect that it might be a pair as one of them is much wider and has a rounder belly. One of them also has a lot of spots on the belly while the other one has almost no spots.
