I had 2 albino corys (originally had 7, 5 of which died after the use of API Algae Fix), but I recently added 4 more once my new tank was cycled. I purchased these 4 from a LFS
that specializes in fish and reptiles. 2 of the corys I bought look quite pink when next to my other corys, but I was assuming it was just a color variation. However, when I got home today, one of the pink ones was dead. I read tonight that a pink tone means exposure to poor-quality water and I'm wondering if there's any truth behind this? I will say that I tested the water in the bag when the fish came home and was VERY disappointed! The ammonia was 8.0 ppm
and nitrite was 5.0 ppm
, so I have no doubt they were in poor-quality water :-( Not sure if there's much I can do for the other pink one if this is what caused him to turn pink, but I do weekly water changes, have high quality filters and my readings are 0, 0, and 10. Just want to know if anyone has experience on this subject. I've attached the best picture I could get, he's still very active at this point while the other was not.
