Hi guys. Been five days since the rescape and had a littlw ammonia spike, but gradually getting it down, it was at 0.25ppm today. Now I read it is normal for Corys to lighten up to match the substrate.Baring in mind ive gone one extreme to the other. Dark Gravel to light sand....
I can deal with that with most of them, but my 2nd big female is almost transparent!! She seems well, moving like the rest,eating, pooping the kinda things fish do. Should I be worried? Ive been doing daily 30% water changes to get on top of ammonia, but my othet parameters are pretty good with 0 nitrite and 10-20 nitrate.
You can see in pic below just how much lighter she is with the male next to her, and he is a fair bit lighter than previous...
