Hi guys,
I recently got a beautiful male leucistic, but have noticed that he had a real yellow tinge. On a closer look, he has quite a lot of yellow through him, on his face/head and down his back. Can anyone tell me why this is, please?
TIA ?

'leucisitc' is not actually a colour the same way that albino is. Albino is where an animal cannot make dark pigment, melanoid is where they can't make shiny pigment, and axanthic is where they can't make yellow pigment.

In leucisitcs they can make all 3 pigments, but during their development the pigments don't migrate through their body and stay confined to the head/face and spine.
So your leucisitc is showing xanthaphores (yellow pigment) across his head and down his spine. This is more usual with melanophores (dark pigment) resulting in a 'dirty leucistic'.

    Hello. I just noticed two notches, white small bubbles on the hind legs of one of my male newts.

    Hey everyone, just want a little advice. Its 55 - 60 celcius in my Salamanders tank. Hes curled up and tyring ti bury himself, Im assuming hes too cold. I was wondering if he would benefit from a heated rock cave (since he LOVES his cave) that I could set on low? I NEVER see him curled up and trying to bury himself unless his tank sits at 63 degrees celcius or lower. So I am assuming hes a little uncomfortable.

    He also seems a little sluggish, again, assuming hes cold. Having heating trouble with the new house right now. What do we think? Was thinking of grabbing this for him since its got very low, medium, and higher medium heat settings that exude heat downward inside the rock cave but ALSO exudes it UPWARDS outside of the rock cave, effectively keeping the tank itself a little warm. Seems like it miiiight be a little small for him though, my guy is about 7 inches from tip of his nose tothe tip of his tail.

    Had a question that I just want to be sure of. My marbled newt is a little over a year old and has started to develop and I noticed that he is starting to swell a little below his abdomen. I guess I’d like to know if they are his testes or if I need to be concerned.
