The first one is an emaciated jungle tremper albino/bell albino...depending on the eyes, and how it looks when it's fattened up. It's a bit hard to tell because of how skinny it is.
The second looks much healthier...it COULD be a mack snow, but i'd be curious to see what colors it was as a true hatchling. It appears as if it could potentially be a normal with lighter yellow, but the only way to tell for sure would be to confirm it with the breeder, or when it grows up, to breed it with a normal het for nothing and see if it produces mack offspring.
Hope this helps. Please get that first little leo some help...and some good gutloaded, dusted mealies.
