I started out with 3 albino corys two weeks ago and lost one within a few days. I replaced it and added two more for a total of 5 albinos. Between two days ago and today I have lost 3 more leaving only two left. I currently have 5 emerald cory, 2 DG and 12neon tetras. All those fish are healthy and active. Today I decided not to get any more albinos and picked up 2 more emeralds and 7 white tip rosy tetras, they are being acclimated now. Could it be just a bad batch of albinos? They are pretty small, way smaller than the emeralds.
