Albino, Leucistic, Xanthic, Melanistic, etc. Fish

Piebald Parancistris

if this is P. aurantiacus which im sure it is, they go through a colour change as they age, so im not sure if its considered piebald. Heres an example, they are darker, start to change and so this piebald effect, then they end up like this (pic 1, 2 and 3&4)

This also happens in Hypostomus luteus... (pics 5-9)
just wondering oddball is there a special name for this, and does it come under the category as leucisitc. Also if you know, what is the cause? Cheers, enjoy pics.

Yep, this characteristic comes with a few 64 cent words:

Usually, radical color changes observed within a species is linked to sexual maturity, spawning, and perhaps territoriality of predominantly males of a population and is termed as polychromatism. If both genders, within a species, share the same color changes and these changes are linked with maturity and aging, then this is termed as the heritability and heterochrony of polychromatism.

Heritability is the extent to which individual phenotypes are determined by their genotypes. (traits passed down through generations)

Heterochrony relates to the timing of development (age triggers)


And, I better not forget my pic.

How about a xanthic cat-fish?

Awesome platinum. FYI, platinum occurrances are termed as Tyrosinase-positive albinism.

and my pic is Chad's xanthic gar pair.

Oddball what would the real term be for my little catfish?

 

[Oddball]

It would be leucistic if it had no yellow. But, with the creamy yellow, it would be a tyrosinase negative leucistic morph.

And...I have to come up with another pic.
