Baby green spotted puffer

[Poseidon82]

My wife brought home 4 gsp about 1 inch long they were starving and nipping each other's fins. After a couple days and a few feedings they have calmed down a little but one has white spots on it's back instead of black spots. The spots on its side are black but white on it's back! Is there an albino variant, is it just stressed out or parasite. Q-tank, ammonia and nitrite 0, nitrate 10, temp 78 f, ph 7.4. These guys are tiny and I can't find any info about there spots being white instead of black. Kinda freaking out
