Default Hypomelanistic A.texanum?

Our ponds fill up with A.texanum larvae, and I noticed & netted this individual the other day. Would it be right to think it's hypomelanistic? Wild type for comparison.

Also, another larvae at the all-you-can-eat daphnia buffet!

Default Re: Hypomelanistic A.texanum?

All my other smallmouth have morphed ages ago, but not this one yet, for some reason. If it stays neotenic, I'll just keep it like a miniature axolotl I suppose 😆.

Do neoteny and hypomelanism go together?

Default Re: Hypomelanistic A.texanum?

Hello,

melanophores expression in phenotype is partially connected with hormones in some animals. There is a possibility that the mutation goes for some kind of hormone deficiency.

Best wishes :)
Nice find by the way!

Good to know - thanks! I have the tank propped at an angle, and he/she has begun to venture shallow half out of water, but the gills haven't shrunk accordingly like the others. I really kind of hope it stays neotenic!

for any interested, gills never went away, and her fins "re-webbed" (if that's a word). So, I have her in a 2.5gal tank worth in 3 inches of fresh spring water, as she's thriving. Ese tually, she's a miniature hypo axolotl. Eats mosquito larvae and small earthworm bits. About 2.5 inches long.

Moved to a custom long I built from glass display shelves. End is walled off (rocks hot glued) which allows for filtration with minimal current. Next year I'll be looking very hard for more.
