Albino, but what strain? Kahl or Sharp? Straight albino or is there anything else in there?
What do the parents look like?
Without other Genes, albinos tend to fade with age. Kahl more so. You lose a lot of the contrast they have when younger.
Still beautiful.
The other may hold color and contrast better, depending on genetics.
Temperament? Any difference or both chill and good eaters?
Also, depending on depth, a 4ft tank can be a life tank for a male BCI if not overfed.
