Question: Whats the key to pretty frills?

[fishoutofh2o88]

What is the key to pretty frills? I have one axolotl with long beautiful frills, then another in the same tank with short choppy frills....I thought it was all about the water quality...but why would one be perfect and the other not?

Ok just to clarify I noticed I posted a pictures with black sand and white Sand...they are both in the same tank I had just switched sand the picture of the Lucy was an older picture. Still accurate to how her frills look now.

Beyond normal genetics, gill fullness is usually attributed to oxygen saturation. Counterintuitive, but lower oxygen saturation leads to fluffier gills, as they need more gill surface area to get necessary oxygen from the water. If you have too much aeration, the gills will atrophy, as they're not needed.
