Congrats on the babies! I never got any albinos when I was breeding Sterbai but they are not too uncommon, just google for: albino cory sterbai
I used to breed them in bare 10 gallon tanks, one pair per tank, with a sponge filter in the back corner, and a handful of Java moss that floated freely and tumbled in the current from the sponge filter. A few days of heavy feeding and then a 50% water change with cooler water usually triggered spawning. They'd stick their eggs to the Java moss, and I'd use a tweezer to pluck out the bits of moss that had eggs atached (to avoid handling the eggs directly) and move them to a small container with gentle aeration until they hatched.
