I have a few axie larvae at about 2 weeks old right now (1.75cm). I can see that I have Melanoid, Wild Type and Albinos.. I'm wondering if any that I assume are melanoid or wilds will lighten up and turn out to be leusistics, or are the basic color types developed already?

The mother is a wild type and the father is a leusistic. I hope to have some leusistic in the batch!


Thanks!

Leucistic larvae are usually pretty obvious - they are white with black eyes. Larvae usually get darker as they grow, so I doubt you have any.

However, this more or less gives away all the genetics of you parents:
Wildtype: D/D M/m A/a Ax/-
Leucistic: D/d M/m A/a -/-
This means you'll not get leucistics because of the D gene, but some of your albinos will likely be goldens and some melanoid.

That said, check out my "egg laying in progress" topic. All of my leucistics came spotted, and now at almost 2 months, their spots are less prevalent, but still there along fin/on face on most of them.

True, but you can't really mistake a wildtype for a leucistic at 2 weeks, the base colour is different.
I have some pale wildtypes in my most recent batch, but there's no way you could imagine they would be leucistic because there is a yellowness you wouldn't get in a leucistic larva.

Maybe the OP can post some photos so we can see?

Pictures are always best! No mention of it, bit GFP can also mess up perception. Still can't tell on some of mine if they are Goldens or albinos getting a yellow color due to thin skin and GFP.

I can help you with that one - do you have photoshop or lightroom? Take a pic, convert to B&W, then darken the yellow hues in the B&W photo. If it loooks like a spotted wildtype its golden, if it looks even toned it's not.

That might work...or might not. Who knows. The GFP further throws it off even in the leucistics. I have non-GFP "pink" ones and yellow/olive colored GFP leucys.

Here they are in their tanks:

Second tank on right, top left and center - two Leucys of different color due to GFP.

Here's my 5 gilled Albino:

Leucistic with some spots still there:

Spot the Wildtype with the weird eye:

What I'm sure is my golden (but also GFP) albino, a regular (non GFP) albino and a GFP Wildtype.

I don't think the 5 gilled one has enough bloodworms. ;)

Looking again at my babies, I assume that auntiejude is right! None of my melanoid or wild type babies look like they stand out too much from the pack! Thanks for you help :)

    with axolotls would I basically have to keep buying and buying new axolotls to prevent inbred breeding which costs a lot of money??

    Not necessarily but if you’re wanting to continue to grow your breeding capacity then yes. Breeding axolotls isn’t a cheap hobby nor is it a get rich quick scheme. It costs a lot of money and time and deditcation

    Would Chinese fire belly newts be more or less inclined towards an aquatic eft set up versus Japanese . I'm raising them and have abandoned the terrarium at about 5 months old and switched to the aquatic setups you describe. I'm wondering if I could do this as soon as they morph?
