I've kept many (maybe 8 or so!!) tiger shovelnose and as far as I know there are 3 distinct species and only one (P. tigrinum) is commonly available.
The spotted shovelnose (P. corruscans) was definitely different even at that size. Unfortunately, one of my fish ate the thing 2 days later!! lol So I was unable to have anymore updates. I was one of the few that bought the fish from WaterLife, and I've never heard from any other buyers of that fish since. As far as I know, it was the only shipment here of that species ever.
I sold everything that same year to Jon Rare (and some others, I don't remember), and in 2005 I kept a small Peruvian rhomb... then I switched to mub puffers, widebar datnoids, african tigers, FRTs, clown loaches, Lates sp., perches, and a whole bunch of others. I will see if I can dig up any more pictures of the collection I had following this one.
