Well, all the ramshorns I have and seen are this way. I've occasionally seen unspotted young, but I've never seen one that has kept the spots throughout it's entire life.
Yes, leopard rams are a true color morph and will retain that color throughout their lives. You may be confused - some snails, like striped brigs, haustrums and canas, hatch with spots that eventually turn into stripes.
Well then, can someone show me a full-grown leopard ramshorn, because I've never seen one.
As for my ramshorns, they all carry the spots as young and lose them as they mature. This includes all colors - browns, reds, blues, etc. As for confusing them with other snails, I don't keep brigs, haustrums or canas.
Vampie, we're not trying to jump on you about this or get smart. The photo posted by the OP is of adult leopard rams and juvies. They're quite common on aquabid and many members here have them as well.
Perhaps you have a slightly different variety of rams that have spots as juveniles - no one is doubting you, but it's not the standard for rams.
Don't worry about jumping on me or anything, I'm just interested in knowing if they is truly a variety of ramshorn that is spotted throughout it's entire lifespan, as I haven't come across any solid proof yet.
The thing about the OP's photo (and the ones I've seen on Aquabid/eBay as well) is that all of the snails simply look like juvenile regular ramshorns given the size as well as the shape and assumed thickness of the shells. As for ramshorns having spots only when young, all of mine are this way, as well as the ones I've seen at stores and my friends' tanks. My own ramshorns are also from several different sources. Whether or not this is the standard for ramshorns, you can see why I would think that it is.
These are great snails though IMO. Hardy, colorful, active, I'd definitely put them above pond snails.
